The article examines the initial period of the mandate administration of Iraq by Great Britain, the anti-British uprising of 1920. The chronological framework covers the period from May 1916 to October 1921 and includes an analysis of events in the Middle East from May 1916, when the secret agreement on the division of the territories of the Ottoman Empire after the end of World War I (the Sykes-Picot agreement) was concluded before the proclamation of Faisal as king of Iraq and from the formation of the country՚s government. This period is a key one in the Iraqi-British relations at the turn of the 10-20s of the ХХ century. The author focuses on the Anglo-French negotiations during the First World War, on the eve and during the Paris Peace Conference on the division of the territory of the Ottoman Empire and the ownership of the territories in the Arab zone. During these negotiations, it was decided to transfer the mandates for Syria (with Lebanon) to the France, and Palestine and Mesopotamia (Iraq) to Great Britain. The British in Iraq immediately faced strong opposition from both Sunnis and Shiites, resulting in an anti-English uprising in 1920. The author describes the causes, course and consequences of this uprising.
