Anglo-Iraqi Treaty in the context of "Anglo-Iraqi Treaty (1930)"

The Mandate for Mesopotamia (Arabic: الانتداب على بلاد ما بين النهرين, romanized: al-Intidāb ʿalā Bilād mā bayn an-Nahrayn) was a proposed League of Nations mandate to cover Ottoman Iraq (Mesopotamia). It would have been entrusted to the United Kingdom but was superseded by the Anglo-Iraqi Treaty, an agreement between Britain and Iraq with some similarities to the proposed mandate. On paper, the mandate lasted from 1920 to 1932.

The proposed mandate was awarded on 25 April 1920 at the San Remo Conference, in Italy, in accordance with the 1916 Sykes–Picot Agreement but was not yet documented or defined. It was to be a class A mandate under Article 22 of the Covenant of the League of Nations. A draft mandate document was prepared by the British Colonial Office in June 1920 and submitted in draft form to the League of Nations in December 1920.

The Hashemite Kingdom of Iraq was the Iraqi state located in the Middle East from 1932 to 1958. It was founded on 23 August 1921 as the Kingdom of Iraq, following the defeat of the Ottoman Empire in the Mesopotamian campaign of the First World War. Although a League of Nations mandate was awarded to the United Kingdom in 1920, the 1920 Iraqi revolt resulted in the scrapping of the original mandate plan in favour of a formally sovereign Iraqi kingdom, but one that was under effective British administration. The plan was formally established by the Anglo-Iraqi Treaty.

The role of the United Kingdom in the formal administration of the Kingdom of Iraq was ended in 1932, following the Anglo-Iraqi Treaty (1930). Now officially a fully independent kingdom, officially named the Hashemite Kingdom of Iraq, it underwent a period of turbulence under its Hashemite rulers throughout its entire existence. Establishment of Sunni religious domination in Iraq was followed by Assyrian, Yazidi and Shi'a unrests, which were all brutally suppressed. In 1936, the first military coup took place in the Hashemite Kingdom of Iraq, as Bakr Sidqi succeeded in replacing the acting Prime Minister with his associate. Multiple coups followed in a period of political instability, peaking in 1941.

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, following the 1920 Iraqi Revolution against the proposed British Mandate of Mesopotamia, and 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 a 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.
