The purpose of the Rowlatt Committee was to evaluate political terrorism in India, especially in the Bengal and Punjab Provinces, its impact, and the links with the German government and the Bolsheviks in Russia. It was instituted towards the end of World War I when the Indian revolutionary movement had been especially active and had achieved considerable success, potency and momentum and massive assistance had been received from Germany, which planned to destabilise British India. These included supporting and financing Indian seditionist organisations in Germany and in United States as well as a destabilisation in the political situation in neighbouring Afghanistan following a diplomatic mission that had attempted to rally the Amir of Afghanistan against British India. Attempts were also made by the Provisional Government of India established in Afghanistan following the mission to establish contacts with the Bolsheviks. A further reason for institution of the committee was emerging civil and labour unrest in India around the post-war recession - such as the Bombay mill worker's strikes and unrest in Punjab - and the 1918 flu pandemic that killed nearly 13 million people in the country.
The evidence produced before the committee substantiated the German link, although no conclusive evidence was found for a significant contribution or threat from the Bolsheviks. On the recommendations of the committee, the Rowlatt Act, an extension of the Defence of India Act 1915, was enforced in response to the threat in Punjab and Bengal.
The Rowlatt Act had a significant impact on the political situation of India, irrevocably placing the country on a path of political action headed by Gandhi that ultimately dominated the Indian independence movement for the next 20 years. Also known as the Black Act, it vested the Viceroy's government with extraordinary powers to quell sedition by silencing the press, detaining the political activists without trial, and arresting without warrant any individuals suspected of sedition or treason. In protest, a nationwide cessation of work (hartal) was called, marking the beginning of widespread, although not nationwide, popular discontent.
The agitation unleashed by the acts culminated on 13 April 1919, in the Jallianwala Bagh massacre in Amritsar, Punjab when the British military commander, Brigadier-General Reginald Dyer, blocked the main entrance to the Jallianwallah Bagh, a walled-in courtyard in Amritsar, and ordered his soldiers to fire into an unarmed and unsuspecting crowd of some 5,000 people who had assembled there in defiance of a ban. A total of 1,650 rounds were fired, killing 379 people (as according to an official British commission; Indian estimates ranged as high as 1,500[full citation needed]) and wounding 1,137 in the episode, which dispelled wartime hopes of home rule and goodwill in a frenzy of post-war reaction.
