The '''Hindu–German Conspiracy'''<sup>[[#Note on the name|(Note on the name)]]</sup> was a series of attempts between 1914 and 1917 by [[Indian nationalist movement|Indian nationalist]] groups to create a Pan-Indian rebellion against the [[British Empire]] during [[World War I]]. This rebellion was formulated between the [[Indian revolutionary underground]] and exiled or self-exiled nationalists in the United States. It also involved the [[Ghadar Party]], and in Germany the [[Indian independence committee]] in the decade preceding the Great War.<ref name="Plowman 84">{{Harvnb|Plowman|2003|p=84}}</ref><ref name=Hoover252>{{Harvnb|Hoover|1985|p=252}}</ref><ref name=GBrown300>{{Harvnb|Brown|1948|p=300}}</ref> The conspiracy began at the start of the war, with extensive support from the [[Auswärtiges Amt|German Foreign Office]], the German consulate in [[San Francisco]], and some support from [[Ottoman Turkey]] and the [[Irish republicanism|Irish republican movement]]. The most prominent plan attempted to foment unrest and trigger a Pan-Indian [[mutiny]] in the [[British Indian Army]] from [[Punjab Province (British India)|Punjab]] to [[Singapore]]. It was to be executed in February 1915, and overthrow British rule in the [[Indian subcontinent]]. The [[Ghadar Conspiracy|February mutiny]] was ultimately thwarted when British intelligence infiltrated the [[Ghadarite]] movement and arrested key figures. Mutinies in smaller units and garrisons within India were also crushed.

The Indo-German [[alliance]] and conspiracy were the target of a worldwide British intelligence effort, which successfully prevented further attempts. American intelligence agencies arrested key figures in the aftermath of the [[Annie Larsen affair|''Annie Larsen'' affair]] in 1917. The conspiracy resulted in the [[Lahore Conspiracy Case trial|Lahore conspiracy case]] trials in India as well as the [[Hindu–German Conspiracy Trial]] — at the time the longest and most expensive trial ever held in the United States.<ref name="Plowman 84" />

This series of events was pivotal for the [[Indian independence movement]], and became a major factor in reforming the Raj's Indian policy.<ref name=Popplewell4>{{Harvnb|Popplewell|1995|p=4}}</ref> Similar efforts were made during [[World War II]] in Germany and in Japanese-controlled [[Southeast Asia]]. [[Subhas Chandra Bose]] formed the [[Indische Legion]] and the [[Indian National Army]], and in Italy [[Mohammad Iqbal Shedai]] formed the [[Battaglione Azad Hindoustan]].

==Background==
[[Nationalism]] had become more and more prominent in India throughout the last decades of the 19th century as a result of the [[social]], [[Economics|economic]] and political changes instituted in the country through the greater part of the century.<ref name=Desai30>{{Harvnb|Desai|2005|p=30}}

</ref><ref name=Desai154>{{Harvnb|Desai|2005|p=154}}
</ref> The [[Indian National Congress]], founded in 1885, developed as a major platform for loyalists' demands for [[political liberalization]] and for increased autonomy. The nationalist movement grew with the founding of underground groups in the 1890s. It became particularly strong, radical and violent in [[Bengal]] and in [[Punjab (British India)|Punjab]], along with smaller but nonetheless notable movements in [[Maharashtra]], [[Presidency of Madras|Madras]] and other places of South India.<ref name=Yadav6>{{Harvnb|Yadav|1992|p=6}}
</ref> In Bengal the revolutionaries more often than not recruited the educated youth of the urban [[middle-class]] ''[[Bhadralok]]'' community that epitomized the "classic" [[Indian revolutionary movement|Indian revolutionary]], while in Punjab the rural and military society sustained organized violence.<ref name=Fraser257>{{Harvnb|Fraser|1977|p=257}}

Other related events include:
* the [[1915 Singapore Mutiny]], 
* the [[Annie Larsen affair|Annie Larsen arms plot]], 
* the [[Christmas Day Plot|Jugantar–German plot]], 
* the [[Niedermayer–Hentig Expedition|German mission to Kabul]], 
* by some accounts, the [[Black Tom explosion]] in 1916.

Parts of the [[conspiracy]] also included efforts to subvert the [[British Indian Army]] in the [[Middle Eastern theatre of World War I]].

The controversial [[1905 partition of Bengal]] had a widespread political impact. Acting as a stimulus for radical nationalist opinion in India and abroad, it became a focal issue for Indian revolutionaries.<ref name=Bose117>{{Harvnb|Bose|Jalal|1998|p=117}}</ref><ref name=Dutta135>{{Harvnb|Dutta|Desai|2003|p=135}}</ref><ref name=Bhatt83>{{Harvnb|Bhatt|2001|p=83}}</ref> Revolutionary organizations like [[Jugantar]] and [[Anushilan Samiti]] emerged in the 20th century. Significant events took place, including assassinations and attempted assassinations of [[Civil service|civil servants]], prominent public figures and Indian informants, including an attempt in 1907 to kill Bengal Lieutenant-Governor Sir [[Andrew Fraser (Governor of Bengal)|Andrew Fraser]]. Matters came to a head when the 1912 [[Delhi–Lahore Conspiracy]], led by erstwhile Jugantar member [[Rash Behari Bose]], attempted to assassinate the then-[[Viceroy of India]], [[Charles Hardinge]]. In the aftermath of this event, the British Indian police made concentrated efforts to destroy the Bengali and Punjabi revolutionary underground. Though the movement came under intense pressure for some time, [[Rash Behari Bose|Rash Behari]] successfully evaded capture for nearly three years. By the time World War I began in 1914, the revolutionary movement had revived in Punjab and Bengal. In Bengal the movement, with a safe haven in the French base of [[Chandernagore]], had sufficient strength to all but paralyze the state administration.<ref name=Gupta12>{{Harvnb|Gupta|1997|p=12}}

The earliest mention of a conspiracy for armed revolution in India appears in ''Nixon's Report on Revolutionary Organization'', which reported that [[Jatin Mukherjee]] (Bagha Jatin) and [[Naren Bhattacharya]] had met with the [[William, German Crown Prince|Crown Prince of Germany]] during the latter's visit to [[Calcutta]] in 1912, and received assurances that he would receive arms and ammunition<ref>''Terrorism in Bengal'', Compiled and Edited by A.K. Samanta, Government of West Bengal, 1995, Vol. II, p625.
</ref> At the same time, an increasingly strong [[pan-Islamic movement]] began to develop, mainly in the North and North-West  regions of India. At the onset of the war in 1914, members of this movement formed an important element of the conspiracy.<ref name=Qureshi78/>

At the time of the [[Partition of Bengal (1947)|partition of Bengal]], [[Shyamji Krishna Varma]] founded [[India House]] in London and received extensive support from notable expatriate Indians including [[Madam Bhikaji Cama]], [[Lala Lajpat Rai]], [[S. R. Rana]], and [[Dadabhai Naoroji]]. The organization – ostensibly a residence for Indian students – in reality sought to promote nationalist opinion and pro-independence work. India House drew young radical activists like  [[Madan Lal Dhingra|M. L. Dhingra]], [[Vinayak Damodar Savarkar|V. D. Savarkar]], [[Virendranath Chattopadhyaya|V. N. Chatterjee]], [[M. P. T. Acharya]] and [[Har Dayal|Lala Har Dayal]].<ref name=Bhavans/><ref name=Strachan794/><ref name=Yadav8>{{Harvnb|Yadav|1992|p=8}}</ref> It developed links with the revolutionary movement in India and nurtured it with arms, funds and propaganda. Authorities in India banned ''[[The Indian Sociologist]]'' and other literature published by the House as "seditious". Under V. D. Savarkar's leadership, the House rapidly developed into a centre for intellectual and political activism and a meeting-ground for radical revolutionaries among Indian students in Britain,<ref name=Hopkirk44>{{Harvnb|Hopkirk|1997|p=44}}</ref><ref name=Owen65>{{Harvnb|Owen|2007|p=65}}</ref><ref name=Owen66>{{Harvnb|Owen|2007|p=66}}</ref> earning it the moniker "The most dangerous organization outside India" from [[Valentine Chirol]].<ref name=Chirol148>{{Harvnb|Chirol|2006|p=148}}</ref><ref name=vonPochhammer435>{{Harvnb|von Pochhammer|2005|p=435}}</ref> In 1909 in London M.

===Ghadar Party===

{{Main|Ghadar Party}}

Large-scale Indian [[immigration]] to the [[Pacific coast]] of [[North America]] took place in the 20th-century, especially from Punjab, which faced an [[economic depression]]. The [[Government of Canada|Canadian government]] met this influx with legislation aimed at limiting the entry of [[South Asia]]ns into [[Canada]] and at restricting the political rights of those already in the country. The Punjabi community had hitherto been an important loyal force for the [[British Empire]] and the [[Commonwealth of Nations|Commonwealth]]. The community had expected that its commitment would be honored with the same welcome and rights which the British and colonial governments extended to British and white immigrants. The restrictive legislation fed growing discontent, [[protest]]s and anti-colonial sentiments within the community. Faced with increasingly difficult situations, the community began organizing itself into political groups. Many Punjabis also moved to the United States, but they encountered similar political and social problems.<ref name=Strachan795>{{Harvnb|Strachan|2001|p=795}}
</ref> Meanwhile, India House and nationalist activism of Indian students had begun declining on the east coast of North America towards 1910, but activity gradually shifted west to San Francisco. The arrival at this time of [[Har Dayal]] from Europe bridged the gap between the intellectual agitators in New York and the predominantly Punjabi labor workers and migrants in the west coast, and laid the foundations of the [[Ghadar Party|Ghadar movement]].<ref name="FischerTine335"/>
[[File:Ghadar di gunj.jpg|thumb|right|180px|''[[Ghadar di gunj]]'', an early Ghadarite compilation of [[nationalist]] and [[socialist]] literature, was banned in India in 1913.]]
The Ghadar Party, initially the 'Pacific Coast Hindustan Association', was formed in 1913 in the United States under the leadership of [[Har Dayal]], with [[Sohan Singh Bhakna]] as its president. It drew members from Indian immigrants, largely from Punjab.<ref name=Strachan795/> Many of its members were also from the [[University of California, Berkeley|University of California at Berkeley]] including Dayal, [[Tarak Nath Das]], [[Kartar Singh Sarabha]] and [[Vishnu Ganesh Pingle|V.G. Pingle]]. The party quickly gained support from Indian expatriates, especially in the United States, Canada and Asia. Ghadar meetings were held in [[Los Angeles]], [[Oxford]], [[Vienna]], [[Washington, D.C.]], and [[Shanghai]].<ref name=Deepak441/>

Ghadar's ultimate goal was to overthrow [[British India|British colonial authority in India]] by means of an armed [[revolution]]. It viewed the [[Indian National Congress|Congress]]-led [[Indian independence movement|mainstream movement]] for [[dominion status]] as modest and its constitutional methods as soft. Ghadar's foremost strategy was to entice [[British Indian Army|Indian soldiers]] to revolt.<ref name=Strachan795/> To that end, in November 1913 Ghadar established the ''[[Yugantar Ashram]]'' press in [[San Francisco]]. The press produced the ''[[Hindustan Ghadar]]'' newspaper and other nationalist literature.<ref name=Deepak441/>

Towards the end of 1913, the party established contact with prominent revolutionaries in India, including [[Rash Behari Bose]]. An Indian edition of the ''[[Hindustan Ghadar]]'' essentially espoused the philosophies of [[anarchism]] and [[revolutionary terrorism]] against British interests in India. Political discontent and violence mounted in Punjab, and Ghadarite publications that reached [[Bombay]] from California were deemed seditious and banned by the Raj. These events, compounded by evidence of prior Ghadarite incitement in the [[Delhi-Lahore Conspiracy]] of 1912, led the British government to pressure the American State Department to suppress Indian revolutionary activities and Ghadarite literature, which emanated mostly from San Francisco.<ref name=Sarkar146>{{Harvnb|Sarkar|1983|p=146}}</ref><ref name=Deepak439>{{Harvnb|Deepak|1999|p=439}}</ref>

===Germany and the Berlin Committee===
{{Main|Berlin Committee}}
{{See also|Imperial Germany|Theobald von Bethmann Hollweg|Arthur Zimmermann|Franz von Papen}}
With the onset of [[World War III|World War I]], an Indian revolutionary group called the [[Berlin Committee]] (later called the Indian Independence Committee) was formed in Germany. Its chief [[architect]]s were [[Chempakaraman Pillai|C. R. Pillai]] and [[V. N. Chatterjee]].<ref name=Hoover251/><ref name=Strachan798>{{Harvnb|Strachan|2001|p=798}}</ref> The committee drew members from Indian students and erstwhile members of the India House including [[Abinash Chandra Bhattacharya|Abhinash Bhattacharya]], Dr. Abdul Hafiz, Padmanabhan Pillai, [[A. R. Pillai]], [[M. P. T. Acharya]] and Gopal Paranjape. Germany had earlier opened the [[Intelligence Bureau for the East]] headed by archaeologist and historian [[Max von Oppenheim]]. Oppenheim and [[Arthur Zimmermann]], the State Secretary for Foreign Affairs of the German Empire, actively supported the Berlin committee, which had links with [[Bagha Jatin|Jatin Mukherjee]]— a [[Jugantar Party]] member and at the time one of the leading revolutionary figures in Bengal.<ref name=Gupta12/><ref name=Bhavans/><ref name=Gupta11/><ref name="Puri 1980 p=60">{{Harvnb|Puri|1980|p=60}}</ref> The office of the 25-member committee at No.38 Wielandstrasse was accorded full embassy status.<ref name=Hopkirk96>{{Harvnb|Hopkirk|2001|p=96}}</ref>

German [[Chancellor]] [[Theobald von Bethmann Hollweg]] authorized German activity against British India as World War I broke out in September 1914. Germany decided to actively support the Ghadarite plans.<ref name=Hoover251>{{Harvnb|Hoover|1985|p=251}}</ref> Using the links established between Indian and [[Irish people|Irish]] residents in Germany (including Irish nationalist and poet [[Roger Casement]]) and the German Foreign Office, Oppenheim tapped into the Indo-Irish network in the United States. Har Dayal helped organise the Ghadar party before his arrest in the United States in 1914. He jumped bail and made his way to Switzerland, leaving the party and its publications in the charge of [[Ram Chandra Bharadwaj]], who became the Ghadar president in 1914. The German [[consulate]] in San Francisco was tasked to make contact with Ghadar leaders in California. A [[Navy|naval]] [[lieutenant]] by the name of Wilhelm von Brincken with the help of the Indian nationalist [[journalist]] [[Tarak Nath Das]] and an intermediary by the name of Charles Lattendorf established links with Bharadwaj. Meanwhile, in Switzerland the Berlin committee was able to convince Har Dayal that organising a revolution in India was feasible.<ref name=Hoover252/>

The Canadian government banned the passengers from landing in Canada and the ship was forced to return to India. The events surrounding the ''Komagata Maru'' incident served as a catalyst for the Ghadarite cause.]]

In May 1914, the Canadian government refused to allow the 400 Indian passengers of the ship ''[[Komagata Maru]]'' to disembark at [[Vancouver]]. The voyage had been planned by [[Baba Gurdit Singh|Gurdit Singh Sandhu]] as an attempt to circumvent Canadian exclusion laws that effectively prevented Indian immigration. Before the ship reached Vancouver, German radio announced its approach, and [[British Columbia]]n authorities prepared to prevent the passengers from entering Canada. The ship was escorted out of Vancouver by the [[protected cruiser]] {{HMCS|Rainbow|1891|6}} and returned to India.

The incident became a focal point for the Indian community in Canada, which rallied in support of the passengers and against the government's policies. After a two-month legal battle, 24 of the passengers were allowed to immigrate. On reaching Calcutta, the passengers were detained under the [[Defence of India Act 1915|Defence of India Act]] at [[Budge Budge]] by the British Indian government, which tried to forcibly transport them to Punjab. This caused rioting at Budge Budge, resulting in fatalities on both sides.<ref name=Ward79>{{Harvnb|Ward|2002|pp=79–96}}</ref> Ghadar leaders like Barkatullah and [[Tarak Nath Das]] used the inflammatory passions surrounding the ''Komagata Maru'' event as a rallying point and successfully brought many disaffected Indians in North America into the party's fold.<ref name="strachan796">{{Harvnb|Strachan|2001|p=796}}</ref>

The [[British Indian Army]], meanwhile, contributed significantly to the [[Allies of World War I|Allied]] war effort in World War I. Consequently, a reduced force, an estimated 15,000 troops in late 1914, was stationed in India.<ref name=Strachan793>{{Harvnb|Strachan|2001|p=793}}</ref> It was in this scenario that concrete plans for organising [[Rebellion|uprisings]] in India were made.

In September 1913 a Ghadarite named Mathra Singh visited [[Shanghai]] to promote the nationalist cause amongst Indians there, followed by a visit to India in January 1914, when Singh circulated Ghadar literature amongst Indian soldiers through clandestine sources before leaving for [[Hong Kong]]. Singh reported that the situation in India was favorable for revolution.<ref name="strachan796"/><ref name=Deepak442>{{Harvnb|Deepak|1999|p=442}}</ref>

By October 1914, many Ghadarites had returned to India and were assigned tasks like contacting Indian revolutionaries and organizations, spreading propaganda and literature, and arranging to get arms into the country.<ref name=Sarkar148>{{Harvnb|Sarkar|1983|p=148}}</ref> The first group of 60 Ghadarites led by Jawala Singh left San Francisco for [[Guangzhou|Canton]] aboard the steamship ''Korea'' on 29 August. They were to sail on to India, where they would be provided with arms to organise a revolt. At Canton, more Indians joined, and the group, now numbering about 150, sailed for Calcutta on a Japanese vessel. They were to be joined by more Ghadarites arriving in smaller groups. During September and October, about 300 Indians left for India in various ships like the SS ''Siberia'', ''Chinyo Maru'', ''China'', ''Manchuria'', ''[[SS Tenyo Maru]]'', SS ''Mongolia'' and ''[[SS Shinyō Maru]]''.<ref name=Hoover251/><ref name=Deepak442/><ref name=Sarkar148/> Although the ''Korea'''s party was uncovered and arrested on their arrival at Calcutta, a successful underground network was established between the United States and India, through Shanghai, [[Swatow]], and [[Siam]]. Tehl Singh, the Ghadar operative in Shanghai, is believed to have spent $30,000 on helping  revolutionaries to get into India.<ref name=GBrown303>{{Harvnb|Brown|1948|p=303}}</ref> The Ghadarites in India were able to establish contact with sympathisers in the [[British Indian Army]] and build networks with underground revolutionary groups.

===East Asia===
Efforts had begun as early as 1911 to procure arms and smuggle them into India.<ref name=Plowman87>{{Harvnb|Plowman|2003|p=87}}</ref> When a clear idea of the conspiracy emerged, more earnest and elaborate plans were made to obtain arms and to enlist international support. [[Herambalal Gupta]], who had arrived in the United States in 1914 at the [[Berlin Committee]]'s directive, took over the leadership of American wing of the conspiracy after the failure of the SS ''Korea'' mission. Gupta immediately began efforts to obtain men and arms. While men were in plentiful supply with more and more Indians coming forward to join the Ghadarite cause, obtaining arms for the uprising proved to be more difficult.<ref name="GBrown301"/>

The revolutionaries started negotiations with the Chinese government through James Dietrich, who held [[Sun Yat-sen]]'s power of attorney, to buy a million [[rifle]]s. However, the deal fell through when they realized that the weapons offered were obsolete [[flintlock]]s and [[muzzle loader]]s. From China, Gupta went to Japan to try to procure arms and to enlist Japanese support for the Indian independence movement. However, he was forced into hiding within 48 hours when he came to know that the Japanese authorities planned to hand him over to the British.<ref name=GBrown301>{{Harvnb|Brown|1948|p=301}}</ref> Later reports indicated he was protected at this time by [[Toyama Mitsuru]], right-wing political leader and founder of the [[Genyōsha|Genyosha]] nationalist secret society.<ref name=Popplewell276>{{Harvnb|Popplewell|1995|p=276}}</ref>

The Indian [[Nobel laureate]] [[Rabindranath Tagore]], a strong supporter of [[Pan-Asianism]], met Japanese premier [[Count Terauchi]] and [[Count Okuma]], a former premier, in an attempt to enlist support for the Ghadarite movement.<ref name=GBrown306>{{Harvnb|Brown|1948|p=306}}</ref> [[Tarak Nath Das]] urged Japan to align with Germany, on the grounds that American war preparation could actually be directed against Japan.<ref name=GBrown306/> Later in 1915, [[Abani Mukherji]]— a Jugantar activist and associate of [[Rash Behari Bose]]— is also known to have tried unsuccessfully to arrange for arms from Japan.The ascendancy of [[Li Yuanhong]] to Chinese Presidency in 1916 led to  negotiations reopening through his former private secretary, who resided in the United States at the time. In exchange for allowing arms shipments to India through China, China was offered German military assistance and the rights to 10% of any material shipped to India via China. The negotiations were ultimately unsuccessful due to [[Sun Yat-sen]]'s opposition to an alliance with Germany.<ref name=GBrown307>{{Harvnb|Brown|1948|p=307}}</ref>

The Indian nationalists then [[Paris Indian Society|in Paris]] had, with Egyptian revolutionaries, made plans to assassinate [[Herbert Kitchener, 1st Earl Kitchener|Lord Kitchener]] as early as 1911, but did not implement them.<ref name=Popplewell224>{{Harvnb|Popplewell|1995|p=224}}</ref> After the war began, this plan was revived, and Har Dayal's close associate [[Gobind Behari Lal]] visited [[Liverpool]] in March 1915 from New York to put this plan in action. He may also have intended at this time to bomb the docks in Liverpool. However, these plans ultimately failed.<ref name=Popplewell224/> [[Virendranath Chattopadhyaya|Chattopadhyaya]] also attempted at this time to revive links with the remnants of [[India House]] that survived in London, and through Swiss, German and English sympathisers then resident in Britain. Among them were Meta Brunner (a Swiss woman), Vishna Dube (an Indian man) and his common law German wife Anna Brandt, and Hilda Howsin (an English woman in Yorkshire). Chattopadhyaya's letters were however traced by the censors, leading to the arrest of the cell members.<ref name=Popplewell225>{{Harvnb|Popplewell|1995|p=225}}</ref> Among other plans that were considered at this time were conspiracies in June 1915 to assassinate Foreign Secretary [[Edward Grey, 1st Viscount Grey of Fallodon|Sir Edward Grey]] and War Minister [[Herbert Kitchener, 1st Earl Kitchener|Lord Kitchener]]. In addition, they also intended to target French President [[Raymond Poincaré]] and Prime Minister [[René Viviani]], King [[Victor Emmanuel III of Italy]] and his prime minister [[Antonio Salandra]]. These plans were coordinated with the [[Italian anarchist]]s, with explosives manufactured in Italy. Barkatullah, by now in Europe and working with the Berlin Committee, arranged for these explosives to be sent to the German consulate in Zurich, from where they were expected to be taken charge of by an Italian anarchist named Bertoni. However, British intelligence was able to infiltrate this plot, and successfully pressed Swiss police to expel Abdul Hafiz.<ref name=Popplewell225/>

In the United States, an elaborate plan and arrangement was made to ship arms from the country and from the [[Far East]] through Shanghai, [[Jakarta|Batavia]], [[Bangkok]] and [[Burma]].<ref name="GBrown301"/> Even while Herambalal Gupta was on his mission in China and Japan, other plans were explored to ship arms from the United States and East Asia. The German high command decided early on that assistance to the Indian groups would be pointless unless given on a substantial scale.<ref name=Fraser261/> In October 1914, German Vice Consul E.H von Schack in San Francisco approved the arrangements for the funds and armaments. The German military attaché Captain [[Franz von Papen]] acquired $200,000 worth of small arms and ammunition through [[Krupp]] agents, and arranged for its shipment to India through San Diego, Java, and Burma. The arsenal included 8,080 [[Springfield rifle]]s of [[Spanish–American War]] vintage, 2,400 [[M1903 Springfield rifle|Springfield carbines]], 410 [[Hotchkiss et Cie|Hotchkiss]] [[repeating rifle]]s, 4,000,000 [[Cartridge (firearms)|cartridges]], 500 [[Colt revolver]]s with 100,000 cartridges, and 250 [[Mauser#Mauser 1910 and 1914 Pocket Pistols|Mauser pistols]] along with ammunition.<ref name=Fraser261>{{Harvnb|Fraser|1977|p=261}}</ref> The [[schooner]] ''[[Annie Larsen]]'' and the sailing ship SS ''Henry S'' were hired to ship the arms out of the United States and transfer it to the {{SS|Maverick}}.

Although the shipment was meant to supply the mutiny planned for February 1915, it was not dispatched until June. By then the conspiracy had been uncovered in India, and its major leaders had been arrested or gone into hiding. The shipment itself failed when disastrous co-ordination prevented a successful rendezvous off [[Socorro Island]] with the ''Maverick''. The plot had already been infiltrated by British intelligence through Indian and Irish agents linked closely with the conspiracy. Upon her return to [[Hoquiam, Washington]] after several failed attempts, the cargo of the ''Annie Larsen'' was seized by US customs.<ref name=HistoryLink/><ref name=Hoover256/> The cargo was sold at auction despite German Ambassador Count [[Johann von Bernstoff]]'s attempts to take possession, insisting it was meant for [[German East Africa]].<ref name=GBrown304>{{Harvnb|Brown|1948|p=304}}</ref> The [[Hindu–German Conspiracy Trial]] opened in 1917 in the United States on charges of gun running and at the time was one of the lengthiest and most expensive trials in American legal history.<ref name="Plowman 84" />
Franz von Papen attempted to sabotage rail lines in Canada and destroy the [[Welland Canal]]. He also
attempted to supply rifles and dynamite to Sikhs in British Columbia for blasting railway bridges. These plots in Canada did not materialise.
Among other events in the United States that have been linked to the conspiracy is the [[Black Tom explosion]] when, on the night of 30 July 1916, saboteurs blew up nearly 2 million tons of arms and ammunition at the Black Tom terminal at New York harbour, awaiting shipment in support of the British war effort. Although blamed solely on German agents at the time, later investigations by the Directorate of Naval Intelligence in the aftermath of the ''Annie Larsen'' incident unearthed links between the Black Tom explosion and Franz von Papen, the Irish movement, the Indian movement as well as Communist elements active in the United States.<ref name=NYTimes>{{cite web

{{See also|1915 Singapore Mutiny|Ingress into India Ordinance, 1914}}
By the start of 1915, many Ghadarites (nearly 8,000 in the Punjab province alone by some estimates) had returned to India.<ref name=Gupta12/><ref>{{Harvnb|Chhabra|2005|p=597}}</ref> However, they were not assigned a central leadership and begun their work on an ''ad hoc'' basis. Although some were rounded up by the police on suspicion, many remained at large and began establishing contacts with garrisons in major cities like [[Lahore]], [[Ferozepur]] and [[Rawalpindi]]. Various plans had been made to attack the military arsenal at Mian Meer, near Lahore and initiate a general uprising on 15 November 1914. In another plan, a group of Sikh soldiers, the ''manjha jatha'', planned to start a mutiny in the 23rd Cavalry at the Lahore cantonment on 26 November. A further plan called for a mutiny to start on 30 November from Ferozepur under Nidham Singh.<ref name=Deepak443>{{Harvnb|Deepak|1999|p=443}}</ref> In Bengal, the Jugantar, through [[Jatindranath Mukherjee|Jatin Mukherjee]], established contacts with the garrison at [[Fort William, India|Fort William]] in Calcutta.<ref name=Gupta12/><ref name=Gupta11>{{Harvnb|Gupta|1997|p=11}}</ref> In August 1914, Mukherjee's group had seized a large consignment of guns and ammunition from the Rodda company, a major gun manufacturing firm in India. In December 1914, several politically motivated [[robbery|armed robberies]] to obtain funds were carried out in Calcutta. Mukherjee kept in touch with Rash Behari Bose through Kartar Singh and V.G. Pingle. These rebellious acts, which were until then organised separately by different groups, were brought into a common umbrella under the leadership of Rash Behari Bose in North India, V. G. Pingle in [[Maharashtra]], and [[Sachindranath Sanyal]] in [[Benares]].<ref name=Gupta12/><ref name=Gupta11/><ref name="Puri 1980 p=60"/> A plan was made for a unified general uprising, with the date set for 21 February 1915.<ref name=Gupta12/><ref name=Gupta11/>

===February 1915===
[[File:1915 Singapore Mutiny.jpg|thumb|The public executions of convicted mutineers at [[Outram Road]], Singapore, c. March 1915]]
In India, unaware of the delayed shipment and confident of being able to rally the Indian [[sepoy]], the plot for the mutiny took its final shape. Under the plans, the 23rd Cavalry in Punjab was to seize weapons and kill their officers while on roll call on 21 February.<ref name=strachan796/> This was to be followed by mutiny in the 26th Punjab, which was to be the signal for the uprising to begin, resulting in an advance on Delhi and Lahore. The Bengal cell was to look for the ''Punjab Mail'' entering the [[Howrah Station]] the next day (which would have been cancelled if Punjab was seized) and was to strike immediately.
However, Punjab CID [[#In Asia|successfully infiltrated]] the conspiracy at the last moment through a sepoy named [[Kirpal Singh (spy)|Kirpal Singh]].<ref name="strachan796"/> Sensing that their plans had been compromised, D-Day was brought forward to 19 February, but even these plans found their way to the intelligence.<ref name="strachan796"/> Plans for revolt by the [[130th Baluchis|130th Baluchi Regiment]] at [[Rangoon]] on 21 January were thwarted. Attempted revolts in the 26th Punjab, 7th Rajput, 130th Baluch, 24th Jat Artillery and other regiments were suppressed. Mutinies in [[Firozpur]], [[Lahore]], and [[Agra]] were also suppressed and many key leaders of the conspiracy were arrested, although some managed to escape or evade arrest. A last-ditch attempt was made by Kartar Singh and V. G. Pingle to trigger a mutiny in the 12th Cavalry regiment at [[Meerut]].<ref name=Gupta3/> Kartar Singh escaped from Lahore, but was arrested in [[Varanasi]], and V. G. Pingle was apprehended in Meerut. Mass arrests followed as the Ghadarites were rounded up in Punjab and the [[Central Provinces]]. Rash Behari Bose escaped from Lahore and in May 1915 fled to Japan. Other leaders, including [[Giani Pritam Singh]], [[Bhavabhushan Mitra|Swami Satyananda Puri]] and others fled to [[Thailand]].<ref name="strachan796"/><ref name=Gupta3/>

On 15 February, the [[5th Light Infantry]] stationed at [[Singapore]] was among the few units [[Singapore Mutiny|to mutiny]] successfully. Nearly eight hundred and fifty of its troops mutinied on the afternoon of the 15th, along with nearly a hundred men of the [[Malay States Guides]]. This mutiny lasted almost seven days, and resulted in the deaths of 47 British soldiers and local civilians. The mutineers also released the interned crew of the [[SMS Emden (1906)|SMS ''Emden'']], who were asked by the mutineers to join them but refused and actually took up arms and defended the barracks after the mutineers had left (sheltering some British refugees as well) until the prison camp was relieved.<ref name=Herbert223/> The mutiny was suppressed only after French, Russian and Japanese ships arrived with reinforcements.<ref name=Sareen1415>{{Harvnb|Sareen|1995|p=14,15}}</ref><ref>{{Harvnb|Kuwajima|1988|p=23}}</ref> Of 200 people tried at Singapore, 47 mutineers were shot in public executions,<ref name=Farwell244>{{Harvnb|Farwell|1992|p=244}}</ref><ref name=Corr15>{{Harvnb|Corr|1975|p=15}}</ref> and the rest were transported for life to East Africa, or given jail terms ranging between seven and twenty years.<ref name=Sareen1415/> In all, 800 mutineers were either shot, imprisoned or exiled.<ref name=Herbert223>{{Harvnb|Herbert|2003|p=223}}</ref> Some historians, including [[Hew Strachan]], argue that although Ghadar agents operated within the Singapore unit, the mutiny was isolated and not linked to the conspiracy.<ref name=Strachan797>{{Harvnb|Strachan|2001|p=797}}</ref> Others deem this as instigated by the [[Silk Letter Movement]] which became intricately related to the Ghadarite conspiracy.<ref name=Qureshi78>{{Harvnb|Qureshi|1999|p=78}}</ref>

===Christmas Day plot===
{{Main|German plot|Bagha Jatin}}
{{See also|Jugantar}}
[[File:BaghaJatin13.jpg|thumb|right|upright|[[Bagha Jatin]], wounded after his final battle at the banks of Burha Balang, off [[Balasore]]. His enterprise was deemed one of the most significant threats to British India in autumn 1915.]]
In April 1915, unaware of the failure of the ''Annie Larsen'' plan, Papen arranged, through [[Krupp]]'s American representative Hans Tauscher, a second shipment of arms, consisting of 7,300 Springfield rifles, 1,930.3 pistols,{{dubious|date=May 2021}} ten [[Gatling gun]]s and nearly 3,000,000 cartridges.<ref name=Fraser263>{{Harvnb|Fraser|1977|p=263}}</ref><ref name=Strachan800/> The arms were to be shipped in mid June to [[Surabaya]] in the [[East Indies]] on the [[Holland America Line|Holland American]] [[steamship]] ''SS Djember''. However, the intelligence network operated by Courtenay Bennett, the [[Consul General]] to New York, was able to trace the cargo to Tauscher in New York and passed the information on to the company, thwarting these plans as well.<ref name=Fraser263/> In the meantime, even after the February plot had been scuttled, the plans for an uprising continued in Bengal through the Jugantar cohort under [[Jatin Mukherjee]] (Bagha Jatin). German agents in Thailand and Burma, most prominently Emil and Theodor Helferrich— brothers of the German Finance minister [[Karl Helfferich]]— established links with Jugantar through [[Jitendra Nath Lahiri|Jitendranath Lahiri]] in March that year. In April, Jatin's chief lieutenant [[Narendranath Bhattacharya]] met with the Helfferichs and was informed of the expected arrival of the ''Maverick'' with arms. Although these were originally intended for Ghadar use, the Berlin Committee modified the plans, to have arms shipped into India by the eastern coast of India, through Hatia on the [[Chittagong]] coast, [[Raimangal River|Raimangal]] in the [[Sundarbans]] and [[Balasore]] in [[Orissa, India|Orissa]], instead of [[Karachi]] as originally decided.<ref name=Strachan800/> From the coast of the [[Bay of Bengal]], these would be collected by Jatin's group. The date of insurrection was fixed for Christmas Day 1915, earning the name "The Christmas Day Plot".<ref name=Hopkirk189>{{Harvnb|Hopkirk|2001|p=189}}</ref> Jatin estimated that he would be able to win over the 14th [[Rajput Regiment]] in Calcutta and cut the line to [[Madras]] at Balasore and thus take control of Bengal.<ref name=Strachan800/> Jugantar also received funds (estimated to be Rs 33,000 between June and August 1915) from the Helfferich brothers through a fictitious firm in Calcutta.<ref name=Fraser264>{{Harvnb|Fraser|1977|p=264}}</ref> However, it was at this time that the details of the ''Maverick'' and Jugantar plans were leaked to Beckett, the British Consul at Batavia, by a defecting Baltic-German agent under the alias "[[Oren (spy)|Oren]]". The ''Maverick'' was seized, while in India, police destroyed the underground movement in Calcutta as an unaware Jatin proceeded according to plan to the Bay of Bengal coast in [[Balasore]]. He was followed there by Indian police and on 9 September 1915, he and a group of five revolutionaries armed with [[Mauser]] pistols made a last stand on the banks of the river Burhablanga. Seriously wounded in a gun battle that lasted seventy five minutes, Jatin died the next day in Balasore.<ref name=Gupta12/><ref name=Strachan802/>

To provide the Bengal group enough time to capture Calcutta and to prevent reinforcements from being rushed in, a mutiny coinciding with Jugantar's Christmas Day insurrection was planned for Burma with arms smuggled in from neutral Thailand.<ref name=Strachan802>{{Harvnb|Strachan|2001|p=802}}</ref><ref name=Hopkirk179>{{Harvnb|Hopkirk|2001|p=179}}</ref><ref name="Majumdar 1971 p=382">{{Harvnb|Majumdar|1971|p=382}}</ref> Thailand (Siam) was a strong base for the Ghadarites, and plans for rebellion in [[Burma]] (which was a part of [[British India]] at the time) had been proposed by the Ghadar party as early as October 1914, which called for Burma to be used as a base for subsequent advance into India.<ref name=Strachan802/><ref name="Majumdar 1971 p=382"/> This ''Siam-Burma plan'' was finally concluded in January 1915. Ghadarites from branches in China and United States, including Atma Ram, Thakar Singh, and Banta Singh from Shanghai and Santokh Singh and Bhagwan Singh from San Francisco, attempted to infiltrate [[Burma Military Police]] in Thailand, which was composed mostly of Sikhs and Punjabi Muslims. Early in 1915, Atma Ram had also visited Calcutta and Punjab and linked up with the revolutionary underground there, including [[Jugantar]].<ref name=Deepak442/><ref name="Puri 1980 p=60" /> [[Herambalal Gupta]] and the German consul at Chicago arranged to have German operatives George Paul Boehm, Henry Schult, and Albert Wehde sent to Siam through [[Manila]] with the purpose of training the Indians. Santokh Singh returned to Shanghai tasked to send two expeditions, one to reach the Indian border via [[Yunnan]] and the other to penetrate upper Burma and join with revolutionary elements there.<ref name=Deepak443/> The Germans, while in Manila, also attempted to transfer the arms cargo of two German ships, the ''Sachsen'' and the ''Suevia'', to Siam in a [[schooner]] seeking refuge at Manila harbour. However, US customs stopped these attempts. In the meantime, with the help of the German Consul to Thailand Remy, the Ghadarite established a training headquarters in the jungles near the Thai-Burma border for Ghadarites arriving from China and Canada. German Consul General at Shanghai, Knipping, sent three officers of the [[Peking]] Embassy Guard for training and in addition arranged for a Norwegian agent in [[Swatow]] to smuggle arms through.<ref name=Fraser266>{{Harvnb|Fraser|1977|p=266}}</ref> However, the Thai Police high command, which was largely British, discovered these plans and Indian police infiltrated the plot through an Indian secret agent who was revealed the details by the [[Austria-Hungary|Austrian]] [[chargé d'affaires]]. Thailand, although officially neutral, was allied closely with Britain and British India. On 21 July, the newly arrived British Minister Herbert Dering presented Foreign Minister Prince Devawongse with the request for arrest and extradition of Ghadarites identified by the Indian agent, ultimately resulting in the arrest of leading Ghadarites in August. Only a single raid into Burma was launched by six Ghadarites, who were captured and later hanged.<ref name=Strachan802/><ref name=Fraser266/><ref name=Fraser267>{{Harvnb|Fraser|1977|p=267}}</ref>

Also to coincide with the proposed Jugantar insurrection in Calcutta was a planned raid on the [[penal colony]] in the [[Andaman Islands]] with a German volunteer force raised from East Indies. The raid would release the political prisoners, helping to raise an expeditionary Indian force that would threaten the Indian coast.<ref name=Fraser264/><ref name=Hopkirk180>{{Harvnb|Hopkirk|2001|p=180}}</ref> The plan was proposed by [[Vincent Kraft]], a German planter in Batavia who had been wounded fighting in France. It was approved by the foreign office on 14 May 1915, after consultation with the Indian committee, and the raid was planned for [[Christmas Day]] 1915 by a force of nearly one hundred Germans. Knipping made plans for shipping arms to the Andaman islands. However, Vincent Kraft was a [[double agent]], and leaked details of Knipping's plans to British intelligence. His own bogus plans for the raid were in the meantime revealed to Beckett by "[[Oren (spy)|Oren]]", but given the successive failures of the Indo-German plans, the plans for the operations were abandoned on the recommendations of both the Berlin Committee and Knipping.<ref name=Fraser265>{{Harvnb|Fraser|1977|p=265}}</ref>

Efforts were directed at drawing Afghanistan into the war on the side of the [[Central Powers]], which it was hoped would incite a nationalist or pan-Islamic uprising in India and destabilise the British recruiting grounds in Punjab and across India. After Russia's defeat in the 1905 Russo-Japanese war, her influence had declined, and it was Afghanistan that was at the time seen by Britain as the only power in the sub-continent capable of directly threatening India.<ref name=Hughes453>{{Harvnb|Hughes|2002|p=453}}</ref>

In the spring of 1915, an [[Niedermayer–Hentig Expedition|Indo-German expedition]] was sent to Afghanistan via the overland route through Persia. Led by the exiled Indian prince [[Raja Mahendra Pratap]], this mission sought to invite the Afghan Emir [[Habibullah Khan]] to break with Britain, declare his independence, join the war on the Central side, and invade British India. It managed to evade the considerable Anglo-Russian efforts that were directed at intercepting it in Mesopotamia and in the Persian deserts before it reached Afghanistan in August 1915.<ref name=Hopkirk98>{{Harvnb|Hopkirk|2001|p=98}}</ref><ref name=Hopkirk13>{{Harvnb|Hopkirk|2001|pp=136–140}}</ref> In Afghanistan, it was joined in Kabul by members of the pan-Islamic group [[Darul Uloom Deoband]] led by Maulana [[Ubaidullah Sindhi]]. This group had left India for Kabul at the beginning of the war while another group under [[Mahmud al-Hasan]] made its way to [[Hijaz]], where they hoped to seek support from the [[List of leaders of Afghanistan|Afghan Emir]], the [[Ottoman Empire]] and [[Imperial Germany]] for a pan-Islamic insurrection beginning in the [[tribal belt (India)|tribal belt]] of [[North-West Frontier Province (1901–55)|north-west India]].<ref name=Jalal2007105>{{Harvnb|Jalal|2007|p=105}}</ref><ref name=Reetz142>{{Harvnb|Reetz|2007|p=142}}</ref> The Indo-German mission pressed Emir Habibullah to break from his neutral stance and open diplomatic relations with Germany, eventually hoping to rally the Emir to the German war effort.<ref name=Hughes466>{{Harvnb|Hughes|2002|p=466}}</ref><ref name=Hopkirk160>{{Harvnb|Hopkirk|2001|p=160}}</ref> Habibullah Khan vacillated on the mission's proposals through much of the winter of 1915, hoping to maintain his neutral stance till the course of the war offered a concrete picture. However, the mission opened at this time secret negotiations with the pro-German elements in the Emir's court and advisory council, including his brother Nasrullah Khan and son [[Amanullah Khan]]. It found support among Afghan intellectuals, religious leaders and the Afghan press which rallied with increasingly anti-British and pro-Central articles. By 1916 the Raj was forced to intercept copies of the Afghan newspaper ''Siraj al Akhbar'' sent to India.<ref name=Sims-Williams120>{{Harvnb|Sims-Williams|1980|p=120}}</ref> It raised to the Emir a threat of a coup d'état in his country and unrest among his tribesmen, who were beginning to see him as subservient to British authority even as Turkey called for a pan-Islamic Jihad.

In December 1915, the Indian members founded the [[Provisional Government of India]], which it was hoped would weigh on Habibullah's advisory council to aid India and force the Emir's hands. In January 1916, the Emir approved a draft treaty with Germany to buy time. However, the Central campaign in the Middle East faltered at around this time, ending hopes that an overland route through Persia could be secured for aid and assistance to Afghanistan. The German members of the mission left Afghanistan in June 1916, ending the German intrigues in the country.<ref name=Hughes472>{{Harvnb|Hughes|2002|p=472}}</ref> Nonetheless, Mahendra Pratap and his Provisional Government stayed behind, attempting to establish links with Japan, Republican China and Tsarist Russia. After the Russian revolution, Pratap opened negotiations with the Soviet Union, visiting Trotsky in Red Petrograd in 1918, and Lenin in Moscow in 1919 and he visited the Kaiser in Berlin in 1918.<ref name=Andreyev95>{{Harvnb|Andreyev|2003|p=95}}</ref> He pressed for a joint Soviet-German offensive through Afghanistan into India. This was considered by the Soviets for some time after the 1919 coup in Afghanistan in which Amanullah Khan was instated as the Emir and the [[Third Anglo-Afghan War|third Anglo-Afghan war]] began. Pratap may also have influenced the "[[Kalmyk Project]]", a Soviet plan to invade India through Tibet and the Himalayan buffer states.<ref name=Andreyev87>{{Harvnb|Andreyev|2003|p=87}}</ref><ref name=Andreyev96>{{Harvnb|Andreyev|2003|p=96}}</ref>

===Middle East===
{{See also|Middle Eastern theatre of World War I}}
Another arm of the conspiracy was directed at the Indian troops who were serving in Middle East. In the Middle Eastern theatre, members of the Berlin Committee, including [[Har Dayal]] and [[M. P. T. Acharya]], were sent on missions to Baghdad and Syria in the summer of 1915, tasked with infiltrating the Indian Expeditionary Force in southern Mesopotamia and Egypt and to attempt to assassinate British officers.<ref name=McKale127>{{Harvnb|McKale|1998|p=127}}</ref> The Indian effort was divided into two groups, one consisting of a Bengali revolutionary P.N. Dutt (alias Dawood Ali Khan) and [[Pandurang Khankoje]]. This group arrived at Bushire, where they worked with [[Wilhelm Wassmuss]] and distributed nationalist and revolutionary literature among Indian troops in Mesopotamia and Persia. The other group, working with Egyptian nationalists, attempted to block the [[Suez Canal]].<ref name=Acharya35>{{Harvnb|Yadav|1992|p=35}}</ref> These groups carried out successful clandestine work in spreading nationalist literature and propaganda amongst the Indian troops in Mesopotamia, and on one occasion even bombed an officer's [[mess]].<ref name="McKale127"/> Nationalist work also extended at this time to recruiting Indian prisoners of war in [[Constantinople]], [[Bushire]], and [[Kut|Kut-al-Amara]].<ref name=Qureshi78/><ref name=Yadav36/> M. P. T. Acharya's own works were directed at forming the Indian National Volunteer Corps with the help of Indian civilians in Turkey, and to recruiting Indian prisoners of war. He is further known to have worked along with [[Wilhelm Wassmuss]] in Bushire amongst Indian troops.<ref name="Acharya35"/><ref name=Yadav36>{{Harvnb|Yadav|1992|p=36}}</ref> The efforts were, however, ultimately hampered by differences between the Berlin committee members who were predominantly Hindus, and Indian revolutionaries already in Turkey who were largely Muslims.<ref name=McKale127/> Further, the Egyptian nationalists distrusted the Berlin Committee, which was seen by the former as a German instrument.<ref name="Acharya35"/>

Nonetheless, in culmination of these efforts, Indian prisoners of war from France, Turkey, Germany, and [[Mesopotamia]]—especially [[Basra]], [[Bushehr]], and [[Siege of Kut|from Kut al Amara]]—were recruited, raising the Indian Volunteer Corps that fought with Turkish forces on many fronts.<ref name=Qureshi79>{{Harvnb|Qureshi|1999|p=79}}</ref> The Deobandis, led by [[Amba Prasad Sufi]], attempted to organise incursions to the western border of India from Persia, through [[Balochistan]], to Punjab. Amba Prasad was joined during the war by Kedar Nath Sondhi, Rishikesh Letha and Amin Chaudhry. These Indian troops were involved in the capture of the frontier city of Karman, Uzbekistan and the detention of the British consul there, and also successfully harassed [[Percy Sykes]]' Persian campaign against the Baluchi and Persian tribal chiefs who were aided by the Germans.<ref>{{Harvnb|Sykes|1921|p=101}}</ref><ref name=Herbert>{{Harvnb|Herbert|2003|p=}}</ref> The [[Aga Khan]]'s brother was killed while fighting the rebels.<ref>{{cite web

But the war in Europe turned for the worse for Turkey and [[Baghdad]] was captured by the British forces. The Ghadarite forces, their supply lines starved, were finally dislodged. They retreated to regroup at Shiraz, where they were finally defeated after a bitter fight during the siege of [[Shiraz]].

By the end of 1917, divisions had begun appearing between the Ghadar Party in America on the one hand, and the Berlin Committee and the German high command on the other. Reports from German agents working with Ghadarites in Southeast Asia and the United States clearly indicated to the European wing a significant element of disorganisation, as well as unrealism in gauging public mood and support within the Ghadarite organisation. The failure of the February plot, the lack of bases in Southeast Asia following China's participation in the war in 1917, and the problems of supporting a Southeast Asian operation through the sea stemmed the plans significantly. Infiltration by British agents, change in American attitude and stance, and the changing fortunes of the war meant the massive conspiracy for revolution within India never succeeded.<ref name=Strachan805>{{Harvnb|Strachan|2001|p=805}}</ref>

==Counter-intelligence==
{{Main|British counter-intelligence against the Indian revolutionary movement during World War I}}

At the outbreak of the war, Punjab CID sent teams to Hong Kong to intercept and infiltrate the returning Ghadarites, who often made little effort to hide their plans and objectives.<ref name=Popplewell168/> These teams were successful in uncovering details of the full scale of the conspiracy, and in discovering Har Dayal's whereabouts. Immigrants returning to India were double checked against a list of revolutionaries.<ref name=Popplewell194>{{Harvnb|Popplewell|1995|p=194}}</ref>

In Punjab, the CID, although aware of possible plans for unrest, was not successful in infiltrating the conspiracy for the mutiny until February 1915. A dedicated force was formed, headed by the Chief of Punjab CID, and including amongst its members [[Liaqat Hayat Khan]] (later head of Punjab CID himself). In February that year, the CID was successful in recruiting the services of Kirpal Singh to infiltrate the plan. Singh, who had a Ghadarite cousin serving in the 23rd Cavalry, was able to infiltrate the leadership, being assigned to work in his cousin's regiment. Singh was soon under suspicion of being a spy, but was able to pass on the information regarding the date and scale of the uprising to British Indian intelligence.<ref name=Popplewell173>{{Harvnb|Popplewell|1995|p=173}}</ref> As the date for the mutiny approached, a desperate Rash Behari Bose brought forward the mutiny day to the evening of 19 February, which was discovered by Kirpal Singh on the very day. No attempts were made by the Ghadarites to restrain him, and he rushed to inform Liaqat Hayat Khan of the change of plans. Ordered back to his station to signal when the revolutionaries had assembled, Singh was detained by the would-be mutineers, but managed to escape under the cover of answering the call of nature.<ref name=Popplewell173/>

The role of German or Baltic-German double-agents, especially the agent named [[Oren (spy)|"Oren"]], was also important in infiltrating and preempting the plans for autumn rebellions in Bengal in 1915 and in as scuttling [[Bagha Jatin]]'s winter plans that year. Another source, the German double agent [[Vincent Kraft]], a planter from [[Batavia, Dutch East Indies|Batavia]], passed information about arms shipments from Shanghai to British agents after being captured. Maps of the Bengal coast were found on Kraft when he was initially arrested and he volunteered the information that these were the intended landing sites for German arms.<ref name=Hopkirk182>{{Harvnb|Hopkirk|2001|p=182}}</ref> Kraft later fled through Mexico to Japan where he was last known to be at the end of the war.<ref name="Strachan802"/> Later efforts by [[Mahendra Pratap]]'s Provisional Government in Kabul were also compromised by [[Herambalal Gupta]] after he defected in 1918 and passed on information to Indian intelligence.<ref name=Strachan788>{{Harvnb|Strachan|2001|p=788}}</ref>

===Europe and the Middle East===
{{See also|John Wallinger|Indian Political Intelligence Office|East Persia Cordon}}
By the time the war broke out, the [[Indian Political Intelligence Office]], headed by [[John Wallinger]], had expanded into Europe. In scale this office was larger than those operated by the British War Office, approaching the European intelligence network of the [[Secret Service Bureau]]. This network already had agents in Switzerland against possible German intrigues. After the outbreak of the war Wallinger, under the guise of an officer of the British General Headquarters, proceeded to France where he operated from Paris, working with the French political police, the [[Sûreté]].<ref>{{Harvnb|Popplewell|1995|p=216,217}}</ref> Among Wallinger's recruits in the network was [[Somerset Maugham]], who was recruited in 1915 and used his cover as an author to visit Geneva without Swiss interference.<ref name=Popplewell230>{{Harvnb|Popplewell|1995|p=230}}</ref><ref name=Woods55>{{Harvnb|Woods|2007|p=55}}</ref>

Among other enterprises, the European intelligence network attempted to eliminate some of the Indian leaders in Europe. A British agent named Donald Gullick was dispatched to assassinate [[Virendranath Chattopadhyaya]] while the latter was on his way to Geneva to meet [[Mahendra Pratap]] to offer him [[Wilhelm II, German Emperor|Kaiser Wilhelm II]]'s invitation. It is said that Somerset Maugham based several of his stories on his first-hand experiences, modelling the character of [[John Ashenden]] after himself and Chandra Lal after Virendranath. The short story "Giulia Lazzari" is a blend of Gullick's attempts to assassinate Virendranath and [[Mata Hari]]'s story. [[Winston Churchill]] reportedly advised Maugham to burn 14 other stories.<ref>{{Harvnb|Popplewell|1995|p=234}}</ref><ref>{{Harvnb|Barooah|2004|p=}}</ref>

The [[Czechoslovakia|Czech]] revolutionary network in Europe also had a role in uncovering [[Bagha Jatin]]'s plans. The network was in touch with the members in the United States, and may have also been aware of and involved in the uncovering of the earlier plots.<ref>{{Harvnb|Voska|Irwin|1940|p=98,108,120,122,123}}</ref><ref name=Masaryk50>{{Harvnb|Masaryk|1970|p=50,221,242}}</ref><ref>{{Harvnb|Bose|1971|p=233,233}}</ref> The American network, headed by [[E. V. Voska]], was a counter-espionage network of nearly 80 members who, as [[Habsburg]] subjects, were presumed to support Germany, but were involved in spying on German and Austrian diplomats. Voska had begun working with [[Guy Gaunt]], who headed [[Courtenay Bennett]]'s intelligence network, at the outbreak of the war and on learning of the plot from the Czech European network, passed on the information to Gaunt and to [[Tomáš Masaryk]] who further passed on the information the American authorities.<ref name=Masaryk50/><ref>{{Harvnb|Popplewell|1995|p=237}}</ref>

In the Middle East, British counter-intelligence was directed at preserving the loyalty of the Indian sepoy in the face of Turkish propaganda and the concept of ''The Caliph's Jihad'', while a particularly significant effort was directed at intercepting the [[Kabul Mission]]. The [[Seistan Force|East Persian Cordon]] was established in July 1915 in the [[Sistan]] province of Persia to prevent the Germans from crossing into Afghanistan, and to protect British supply caravans in [[Sarhad, Sindh|Sarhad]] from Damani, Reki and Kurdish [[Baloch people|Baluchi]] tribal raiders who may have been tempted by German gold. Among the commanders of the Sistan force was [[Reginald Dyer]] who led it between March and October 1916.<ref name=Collett144>{{Harvnb|Collett|2006|p=144}}</ref><ref name=Popplewell182>{{Harvnb|Popplewell|1995|p=182,183,187}}</ref><ref name=Seidt4>{{Harvnb|Seidt|2001|p=4}}</ref>

===United States===
{{See also|W. C. Hopkinson}}
In the United States, the conspiracy was successfully infiltrated by British intelligence through Irish and Indian channels. The activities of the [[Ghadar Conspiracy|Ghadar]] on the Pacific coast were noted by [[W. C. Hopkinson]], who was born and raised in India and spoke fluent Hindi. Initially Hopkinson had been despatched from Calcutta to keep the Indian Police informed about the doings of [[Taraknath Das]].<ref>{{cite web

The Home department of the British Indian government had begun the task of actively tracking Indian seditionists on the [[East Coast of the United States|East Coast]] as early as 1910.
[[File:Francis Philip Cunliffe-Owen, Vanity Fair, 1878-11-23.jpg|thumb|Francis Cunliffe-Owen]]
 
Francis Cunliffe Owen, the officer heading the Home Office agency in New York, had become thoroughly acquainted with [[George Freeman (newspaper editor)|George Freeman]] alias Fitzgerald and [[Myron Phelps]], the famous New York advocate, as members of the [[Clan-na-Gael]]. Owens' efforts were successful in thwarting the SS ''Moraitis'' plan.<ref>{{Harvnb|Popplewell|1995|p=147}}</ref> The [[Ghadar Party]] was incidentally established after Irish Republicans, sensing infiltration, encouraged formation of an exclusively Indian society.<ref name="Popplewell148"/>

Following this, several approaches were adopted, including infiltration through an Indian national named Bela Singh who successfully set up a network of agents passing on information to Hopkinson, and through the use of the famous American [[Pinkerton's]] detective agency.<ref name=Popplewell148/><ref name=Radhan259>{{Harvnb|Radhan|2002|p=259}}</ref> Bela Singh was later murdered in India in the 1930s.

Charles Lamb, an Irish double agent, is said to have passed on the majority of the information that compromised the ''Annie Larsen'' affair, and ultimately helped the construction of the prosecution. An Indian operative, codenamed "''C''" and described most likely to have been the adventurous Chandra Kanta Chakravarty (later the chief prosecution witness in the trial), also passed on the details of the conspiracy to British and American intelligence.<ref name=Plowman93>{{Harvnb|Plowman|2003|p=93}}</ref>

==Trials==
{{Main|Lahore Conspiracy trial|Hindu–German Conspiracy Trial}}

The conspiracy led to several trials in India, most famous among them the [[Lahore Conspiracy trial]], which opened in Lahore in April 1915 in the aftermath of the failed February mutiny. Other trials included the [[Varanasi|Benares]], [[Shimla]], Delhi, and [[Ferozepur]] conspiracy cases, and the trials of those arrested at Budge Budge.<ref name=Chhabra598>{{Harvnb|Chhabra|2005|p=598}}</ref> At Lahore, a special tribunal was constituted under the [[Defence of India Act 1915]] and a total of 291 conspirators were put on trial. Of these 42 were awarded the death sentence, 114 [[Cellular Jail|transported for life]], and 93 awarded varying terms of imprisonment. Several of these were sent to the [[Cellular Jail]] in the [[Andaman Islands]]. Forty two defendants in the trial were acquitted.
The Lahore trial directly linked the plans made in United States and the February mutiny plot. Following the conclusion of the trial, diplomatic efforts to destroy the Indian revolutionary movement in the United States and to bring its members to trial increased considerably.<ref name=Talbot124>{{Harvnb|Talbot|2000|p=124}}</ref><ref name=Andaman>{{cite web

In the United States, the [[Hindu–German Conspiracy Trial]] commenced in the District Court in San Francisco on 12 November 1917 following the uncovering of the Annie Larsen affair. One hundred and five people participated, including members of the Ghadar Party, the former German Consul-General and Vice-Consul, and other members of staff of the German consulate in San Francisco. The trial itself lasted from 20 November 1917 to 24 April 1918. The last day of the trial was notable for the sensational assassination in a packed courtroom of the chief accused, [[Ram Chandra Bharadwaj|Ram Chandra]], by a fellow defendant, Ram Singh, who believed he was a spy for the British. Singh himself was immediately shot dead by a [[US Marshal]].

In May 1917, a group of Indian nationalists of the Ghadar Party were indicted by a federal grand jury on a charge of conspiracy to form a military enterprise against Britain. In later years the proceedings were criticised as being largely a [[show trial]] designed to appease the [[Government of the United Kingdom|British government]].<ref name=Fraser257/> The jury during the trial was carefully selected to exclude any Irish person with republican views or associations.<ref name=Jensen65/> The trial lasted from November 20, 1917, to April 24, 1918, and resulted in the convictions of 29 people, including 14 Indian nationalists. British colonial authorities hoped the conviction of the Indians would result in their deportation back to India. Had the nationalists been deported to India, they would've faced much harsher sentences, including execution. In contrast to the mass executions in India, the Indian nationalists convicted in the San Francisco trial received prison terms ranged from 30 days to 22 months, as they faced far less serious charges of violating U.S. neutrality laws.<ref name=":0">{{Cite news |date=1918-05-01 |title=Article clipped from The San Francisco Examiner |pages=13 |work=The San Francisco Examiner |url=https://www.newspapers.com/article/the-san-francisco-examiner/128452942/ |access-date=2023-10-04}}</ref>

Strong public support in favour of the Indians, especially the revived Anglophobic sentiments following the provisions of the [[Treaty of Versailles]] which were perceived as being overtly favorable towards Britain, allowed the Ghadarite movement to be revived despite British concerns.<ref name="Dignan75">{{Harvnb|Dignan|1971|p=75}}</ref>

==Impact==
{{Main|Impact of the Hindu–German Conspiracy}}
The conspiracy had a significant impact on Britain's policies, both within the empire and in international relations.<ref name=GBrown300/><ref name=Sarkar146/><ref>{{Harvnb|Dignan|1971|p=57}}</ref><ref name=Majumderxix>{{Harvnb|Majumdar|1971|p=xix}}</ref><ref name=Dignan60>{{Harvnb|Dignan|1971|p=60}}</ref><ref name=Cole>{{Harvnb|Cole|2001|p=572}}</ref> The outlines and plans for the nascent ideas of the conspiracy were noted and tracked by British intelligence as early as 1911.<ref name=Hopkirk41/> Alarmed at the agile organisation, which repeatedly reformed in different parts of the country despite being subdued in others, the chief of Indian Intelligence [[Charles Cleveland (rugby union)|Sir Charles Cleveland]] was forced to warn that the idea and attempts at pan-Indian revolutions were spreading through India "like some hidden fire".<ref name=Hopkirk41/><ref>{{harvnb|Hopkirk|1997|p=43}}</ref> A massive, concerted, and coordinated effort was required to subdue the movement.

===Political impact===

{{See also|Defence of India Act 1915}}
The conspiracy, an important set of events in the Indian independence movement, according to the British Indian Government's own evaluation at the time, as well as those of several contemporary and modern historians, and it was one of the significant threats faced by the Raj in the second decade of the 20th century.<ref>{{harvnb|Sinha|1971|p=153}}</ref><ref>{{harvnb|Ker|1917|p=}}</ref>

Amid the British war effort and the threat from the militant movement in India, the British passed the [[Defence of India Act 1915]]. [[Michael O'Dwyer]], then the Lieutenant Governor of Punjab, was among the strongest proponents of the Act, largely due to the Ghadarite movement.<ref name=Popplewell175>{{Harvnb|Popplewell|1995|p=175}}</ref> It was also a factor that guided British political concessions and Whitehall's India Policy during and after World War I, including the passage of [[Montagu–Chelmsford Reforms]] which initiated the first round of political reform in the Indian subcontinent in 1917.<ref name=Majumderxix/><ref name=Dignan60/><ref name=Cole/> The events of the conspiracy during World War I, the presence of Pratap's Kabul mission in Afghanistan and its possible links to the Soviet Union, and a still-active revolutionary movement especially in Punjab and Bengal (as well as worsening civil unrest throughout India) led to the appointment of a [[Rowlatt Committee|Sedition committee]] in 1918 chaired by [[Sidney Rowlatt]], an English judge. It was tasked to evaluate German and [[Bolshevik]] links to the militant movement in India, especially in Punjab and Bengal. On the recommendations of the committee, the [[Rowlatt Act]], an extension of the Defence of India Act 1915, was enforced in India.<ref name=Popplewell175/><ref name=Lovett>{{Harvnb|Lovett|1920|pp=94, 187–191}}</ref><ref name=Sarkar1921>{{Harvnb|Sarkar|1921|p=137}}</ref><ref name=Tinker92>{{Harvnb|Tinker|1968|p=92,93}}</ref><ref name=Fisher129>{{Harvnb|Fisher|1972|p=129}}</ref>

The events that followed the passage of the Rowlatt Act in 1919 were also influenced by the conspiracy. At the time, British Indian Army troops were returning from the battlefields of Europe and [[Mesopotamia]] to an economic depression in India.<ref>{{Harvnb|Sarkar|1983|pp=169–172,176}}</ref><ref name=FLJR>{{cite web

}}</ref> The attempted mutinies in 1915 and the Lahore conspiracy trials still had the public's  attention. News of young [[Muhajir (Urdu-speaking people)|Mohajirs]] who had fought on behalf of the Turkish Caliphate and later in the ranks of the [[Red Army]] during the [[Russian Civil War]] had also begun to reach India. The Russian Revolution had also cast its long shadow into India.<ref>{{harvnb|Sarkar|1983|p=177}}</ref> It was at this time that [[Mahatma Gandhi]], until then relatively unknown on the Indian political scene, began to emerge as a mass leader.

Ominously, in 1919, the [[Third Anglo-Afghan War]] began in the wake of Amir [[Habibullah Khan|Habibullah]]'s assassination and institution of [[Amānullāh Khān|Amanullah]] in a system blatantly influenced by the Kabul mission. In addition, in India, Gandhi's call for protest against the Rowlatt Act achieved an unprecedented response of furious unrest and protests. The situation, especially in Punjab, was deteriorating rapidly, with disruptions of rail, telegraph and communication systems. The movement was at its peak before the end of the first week of April, with some recording that "practically the whole of Lahore was on the streets, the immense crowd that passed through Anarkali was estimated to be around 20,000."<ref name=FLJR/> In [[Amritsar]], over 5,000 people gathered at [[Jallianwala Bagh massacre|Jallianwala Bagh]]. This situation deteriorated perceptibly over the next few days. Michael O'Dwyer is said to have been of the firm belief that these were the early and ill-concealed signs of a conspiracy for a coordinated uprising around May, on the lines of the [[1857 revolt]], at a time when the British would have withdrawn to the hills for the summer. The [[Amritsar massacre]], as well as responses before and after it, was the result of a concerted plan of response from the Punjab administration to suppress such a conspiracy.<ref>{{Harvnb|Cell|2002|p=67}}</ref> [[James Houssemayne Du Boulay]] is said to have ascribed a direct relationship between the fear of a Ghadarite uprising in the midst of an increasingly tense situation in Punjab, and the British response that ended in the massacre.<ref name=Brown1973>{{Harvnb|Brown|1973|p=523}}</ref>

Lastly, British efforts to downplay and disguise the nature and impact of the revolutionary movement at this time also resulted in a policy designed to strengthen the moderate movement in India, which ultimately saw Gandhi's rise in the Indian movement.<ref name=Popplewell4/>

===International relations===
{{See also|Anglo-American relations|Anglo-Japanese relations}}
The conspiracy influenced several aspects of Great Britain's international relations, most of all [[Anglo-American relations]] during the war, as well as, to some extent, [[China–United Kingdom relations|Anglo-Chinese relations]]. After the war, it also influenced Anglo-Japanese relations.

At the start of the war, the American government's refusal to check the Indian seditionist movement was a major concern for the British government. By 1916, a majority of the resources of the American department of the British Foreign Office were related to the Indian seditionist movement. Before the outbreak of the war, the political commitments of the [[Woodrow Wilson]] government (especially of [[United States Secretary of State|Secretary of State]] [[William Jennings Bryan]] who, eight years previously, had authored "British Rule in India", a highly critical pamphlet, that was classified as seditionist by the Indian and Imperial governments) and the political fallouts of the perception of British persecution of oppressed people prevented then-ambassador [[Cecil Spring Rice]] from pressing the issue diplomatically.<ref name=Strachan800>{{Harvnb|Strachan|2001|p=800}}</ref><ref name=Fraser260>{{Harvnb|Fraser|1977|p=260}}</ref><ref name=Strachan804>{{Harvnb|Strachan|2001|p=804}}</ref> After [[Robert Lansing]] replaced Bryan as Secretary of State in 1916, [[Secretary of State for India]] [[Robert Crewe-Milnes, 1st Marquess of Crewe|Marquess of Crewe]] and Foreign Secretary [[Edward Grey, 1st Viscount Grey of Fallodon|Edward Grey]] forced Spring Rice to raise the issue, and in February the evidence obtained in the Lahore Conspiracy trial were presented to the American government. The first investigations were opened in America with the raid of the Wall Street office of [[Wolf von Igel]], which resulted in seizures of papers that were later presented as evidence in the [[Hindu–German Conspiracy Trial]].<ref name=Strachan804/> However, a perceptibly slow and reluctant American investigation triggered an intense neutrality dispute through 1916, aggravated by belligerent preventive measures of the [[China Station|British Far-Eastern fleet]] on the high seas that threatened the sovereignty of American vessels. German and Turkish passengers were seized from the American vessel ''China'' by ''[[SS Laurentic (1908)|HMS Laurentic]]'' at the mouth of the [[Yangtze River]]. Several incidents followed, including the SS ''Henry S'', which were defended by the British government on grounds that the seized ship planned to foment an armed uprising in India. These drew strong responses from the US government, prompting the [[United States Fleet Forces Command|US Atlantic Fleet]] to dispatch destroyers to the Pacific to protect the sovereignty of American vessels. Authorities in the Philippines were more cooperative, which assured Britain of knowledge of any plans against Hong Kong. The strained relations were relaxed in May 1916 when the Britain released the ''China'' prisoners and relaxed its aggressive policy seeking co-operation with the United States. However, diplomatic exchanges and relations did not improve before November that year.<ref name="Fraser260"/><ref name="Strachan804"/><ref name="Dignan 1971 p">{{Harvnb|Dignan|1971|p=}}</ref>

The conspiracy issue was ultimately addressed by [[William G. E. Wiseman]], head of British intelligence in the United States, when he passed details of a bomb plot directly to the [[New York City Police Department|New York Police]] bypassing diplomatic channels. This led to the arrest of Chandra Kanta Chuckrevarty. As the links between Chuckervarty's papers and the Igel papers became apparent, investigations by federal authorities expanded to cover the entire conspiracy. Ultimately, the United States agreed to forward evidence so long as Britain did not seek admission of liability for breaches of neutrality. At a time that diplomatic relations with Germany were deteriorating, the British Foreign Office directed its embassy to co-operate with the investigations resolving the Anglo-American diplomatic disputes just as the United States entered the war.<ref name=Strachan804/><ref name="Dignan 1971 p"/>

Through 1915–16, China and Indonesia were the major bases for the conspirators, and significant efforts were made by the British government to coax China into the war to attempt to control the German and Ghadar intrigues. This would also allow free purchase of arms from China for the [[Triple Entente|Entente powers]].<ref name=Strachan802/> However, Yuan's proposals for bringing China into the war were against Japanese interests and gains from the war. This, along with Japanese support for [[Sun Yat-Sen]] and rebels in southern China laid the foundations for deterioration of Anglo-Japanese relations as early as 1916.<ref name=Strachan803>{{Harvnb|Strachan|2001|p=803}}</ref> After the end of the Great War, Japan increasingly became a haven for radical Indian nationalists in exile, who were protected by patriotic Japanese societies. Notable among these were Rash Behari Bose, Tarak Nath Das, and [[A. M. Sahay]]. The protections offered to these nationalists, most notably by Toyama Mitsuru's [[Black Dragon Society]],<ref name=Tagore486>{{Harvnb|Tagore|1997|p=486}}</ref><ref name="Brown 1986 p=421">{{Harvnb|Brown|1986|p=421}}</ref> effectively prevented British efforts to repatriate them and became a major policy concern.<ref name="Brown 1986 p=421"/><ref>{{Harvnb|Dignan|1983|p= }}</ref>

===Ghadar Party and IIC===
The IIC was formally disbanded in November 1918. Most of its members became closely associated with [[communism]] and the Soviet Union.<ref name=Strachan815>{{Harvnb|Strachan|2001|p=815}}</ref> [[Bhupendranath Dutta]] and [[Virendranath Chattopadhyay]] alias Chatto arrived in Moscow in 1920. [[Narendranath Bhattacharya]], under a new identity of [[M. N. Roy]], was among the first Indian communists and made a memorable speech in the second congress of the [[Communist International]] that rejected Leninist views and foreshadowed [[Maoist]] peasant movements.<ref name="Tinker92" /> Chatto himself was in Berlin until 1932 as the general secretary of the [[League Against Imperialism]] and was able to convince [[Jawaharlal Nehru]] to affiliate the [[Indian National Congress]] with the league in 1927. He later fled [[Nazi Germany]] for the Soviet Union but disappeared in 1937 under [[Joseph Stalin]]'s [[Great Purge]].<ref name=Fraser269>{{Harvnb|Fraser|1977|p=269}}</ref>

The Ghadar Party, suppressed during the war, revived itself in 1920 and openly declared its communist beliefs. Although sidelined in California, it remained relatively stronger in East Asia, where it allied itself with the [[Chinese Communist Party]].<ref name=Deepak441>{{Harvnb|Deepak|1999|p=441}}</ref><ref name=Fraser269/>

===World War II===
{{Main|Indian Independence League|Indian National Army|Arzi Hukumat-e-Azad Hind}}
Although the conspiracy failed during World War I, the movement being suppressed at the time and several of its key leaders hanged or incarcerated, several prominent Ghadarites also managed to flee India to Japan and Thailand. The concept of a revolutionary movement for independence also found a revival amongst later generation Indian leaders, most notably [[Subhas Chandra Bose]] who, towards the mid-1930s, began calling for a more radical approach towards colonial domination. During World War II, several of these leaders were instrumental in seeking [[Axis powers|Axis support]] to revive such a concept.<ref>{{Harvnb|Lebra|1977|p=23}}</ref><ref>{{Harvnb|Lebra|1977|p=24}}</ref> Bose himself, from the very beginning of World War II, actively evaluated the concept of revolutionary movement against the Raj, interacting with Japan and subsequently escaping to Germany to raise an Indian armed force, the [[Indische Legion]], to fight in India against Britain.<ref name=ThomsonBBC>{{cite news

==Note on the name==
The conspiracy is known under several different names, including the 'Hindu Conspiracy', the 'Indo-German Conspiracy', the 'Ghadar conspiracy' (or 'Ghadr conspiracy'), or the 'German plot'.<ref name=Plowman82>{{Harvnb|Plowman|2003|p=82}}</ref><ref name=Jensen83>{{Harvnb|Jensen|1979|p=83}}</ref><ref name=PlowmanFN2>{{Harvnb|Plowman|2003|p=Footnote 2}}</ref><ref name=Isemonger>{{Harvnb|Isemonger|Slattery|1919|p=}}</ref><ref name=Waldorfweb/> The term ''Hindu–German Conspiracy'' is closely associated with the uncovering of the [[Annie Larsen plot]] in the United States, and the ensuing trial of Indian nationalists and the staff of the German Consulate of San Francisco for violating American neutrality. The trial itself was called the [[Hindu–German Conspiracy Trial]], and the conspiracy was reported in the media (and later studied by several historians) as Hindu–German Conspiracy.<ref name=Jensen65/> However, the conspiracy involved not only Hindus and Germans, but also substantial numbers of Muslims and Punjabi Sikhs, and strong Irish support that pre-dated German and Turkish involvement. The term ''Hindu'' (or ''Hindoo'') was used commonly in opprobrium in America to identify [[Indian people|Indians]] regardless of religion. Likewise, conspiracy was also a term with negative connotations. The term ''Hindu Conspiracy'' was used by the government to actively discredit the Indian revolutionaries at a time the United States was about to join the war against Germany.<ref name=Jensen65>{{harvnb|Jensen|1979|p=65}}</ref><ref>{{harvnb|Jensen|1979|p=67}}</ref><ref name=Strother308>{{harvnb|Strother|2004|p=308}}</ref>

The term '[[Ghadar Conspiracy]]' may refer more specifically to the mutiny planned for February 1915 in India, while the term '[[German plot]]' or '[[Christmas Day Plot]]' may refer more specifically to the plans for shipping arms to Jatin Mukherjee in Autumn 1915. The term ''Indo-German conspiracy'' is also commonly used to refer to later plans in Southeast Asia and to the [[Niedermayer–Hentig Expedition|mission to Kabul]] which remained the remnant of the conspiracy at the end of the war. All of these were parts of the larger conspiracy. Most scholars reviewing the American aspect use the name Hindu–German Conspiracy, the Hindu-Conspiracy or the Ghadar Conspiracy, while most reviewing the conspiracy over its entire span from Southeast Asia through Europe to the United States more often use the term Indo-German conspiracy.<ref name=Waldorfweb>{{cite web| publisher = whereinthecity.com
