During World War I, the British Army defeated the Ottoman Army on the Middle Eastern Front during the Mesopotamian Campaign. Subsequently, the League of Nations designated Mesopotamia as a mandate territory, the British Mandate of Mesopotamia. From 1920 to the early 1930s, "RAF Iraq Command" was created as an inter-service command in charge of all British forces in the mandate-controlled Kingdom of Iraq. The command consisted of Royal Air Force, Royal Navy, British Army, Commonwealth, and locally raised units and was commanded by an RAF officer normally of Air Vice-Marshal rank.
In 1932, the British mandate in Iraq ended. However, per the Anglo-Iraqi Treaty of 1930, the United Kingdom was permitted to maintain troops in Iraq. In 1933 or 1934, RAF Iraq Command was renamed the "British Forces in Iraq." By the late 1930s, these forces were restricted to two Royal Air Force stations, RAF Shaibah near Basra and RAF Habbaniya west of Baghdad.
On 1 April 1941, during World War II, Rashid Ali seized power in Iraq via a coup d'état. He was supported by three top level Royal Iraqi Army officers and one top level Royal Iraqi Air Force officer who were collectively known as the "Golden Square." Rashid Ali proclaimed himself Chief of the "National Defence Government." His new government was immediately recognized by Nazi Germany. It was openly pro-Nazi and anti-British.
The ground forces from India that landed in Basra were initially known as Sabine Force and were under the command of Major-General W.A.K. Fraser. From 8 May 1941, Fraser was replaced and the forces in Basra were commanded by Lieutenant-General Edward Quinan. On 18 June, Quinan was placed in command of all ground forces in Iraq which included both Sabine Force and British Forces in Iraq. Iraqforce was the name of the combined forces. From 21 June, Iraqforce became known as the Iraq Command. On 1 September 1941, after Persia (modern Iran) was secured, Iraq Command was renamed "Persia and Iraq Force" or PAI Force. PAI Force was still commanded by Quinan and he still reported to India Command. Iraqforce was variously part of India Command, Middle East Command and then Persia and Iraq Command.
Sabine Force was initially despatched from Karachi by GHQ India to seize and secure the port of Basra and to supplement the existing British Forces in Iraq at RAF Shaibah and RAF Habbaniya. British Prime Minister Winston Churchill saw Basra as a major supply base in the future for material from the United States. Churchill did not recognize Rashid Ali's "National Defence Government" as legitimate. Churchill also wanted to reinstate a more compliant Iraqi government and to protect British interests in Iraq, notably the oilfields of which the British-owned Anglo-Persian Oil Company was concession holder. On 18 April, a brigade from Karachi landed and Basra was captured and on 30 April, a second brigade arrived. The Rashid Ali government demanded that the British forces be removed from Iraq and Iraqi forces took up positions around RAF Habbaniya. On 2 May, British aircraft from Habbaniya launched a surprise attack on Iraqi forces throughout the country.
During the ensuing war, a force from the British Mandate of Palestine, known as Habbaniya Force (shortened to Habforce), advanced into Iraq from Transjordan. Habforce, with Kingcol in the lead, was to relieve the British garrison forces besieged at the British Royal Air Force treaty base at RAF Habbaniya. The threat to Habbaniya was removed by actions of the Habbaniya garrison before any elements of Habforce arrived. After it arrived, Habforce and a portion of the Habbaniya garrison then advanced onwards through Fallujah to capture Baghdad. By 31 May, an armistice was signed and the government collapsed. From early May, the troops in Iraq were under the operational control of Army Headquarters, Middle East Command in Cairo, reverting to India command on 18 June. From 21 June, Iraqforce became known as the Iraq Command.
In June and July 1941, after Iraq was secured, elements of Iraqforce/Iraq Command took part in the Syria-Lebanon campaign and, while active in Syria, they once more came under the authority of the Cairo Headquarters.
Anglo-Soviet Invasion of Persia
In late August 1941, Iraq Command conducted the Anglo-Soviet invasion of Persia, in conjunction with forces advancing from the Soviet Union. A new formation, Hazelforce, based on the 2nd Indian Armoured Brigade was formed within Iraq Command during this effort. On 1 September, after Persia (modern Iran) was secured, Iraq Command was renamed "Persia and Iraq Force" or Paiforce. Paiforce was still commanded by Quinan and he still reported to India Command. In January 1942, Persia and Iraq once again came under Middle East Command and, in February 1942, Quinan's headquarters was re-designated as Tenth Army.
In 1942, with the growing threat from the German advance in the Caucasus, it was felt that the area should come under a General Headquarters which could bring a specific focus to the area. Previous experience of controlling the area from Cairo and Delhi had not proved ideal and both these General Headquarters were by this time fully committed in the Western Desert Campaign and to the Burma Campaign respectively. In August 1942, it was decided therefore, as part of the changes made bringing in Alexander and Montgomery to Middle East Command and Auchinleck to India Command, to create a new, separate command, the "Persia and Iraq Command," to be led by General Sir Maitland Wilson and based in Baghdad.
