Mandatory Iraq

The Kingdom of Iraq under British Administration, or Mandatory Iraq (Arabic: الانتداب البريطاني على العراق, romanized: al-Intidāb al-Brīṭānī ʿalā l-ʿIrāq), was created in 1921 after the 1920 Iraqi Revolt against the proposed British Mandate of Mesopotamia and was enacted via the 1922 Anglo-Iraqi Treaty and a 1924 undertaking by the United Kingdom to the League of Nations to fulfil the role as mandatory power.

Faisal ibn Husayn, who had been proclaimed King of Syria by the Syrian National Congress in Damascus in March 1920, was ejected by the French in July of the same year. Faisal was then granted by the British the territory of Iraq to rule it as a kingdom, with the British Royal Air Force (RAF) retaining certain military control, but de facto, the territory remained under British administration until 1932.
