The Kingdom of Iraq gains independence from the United Kingdom.

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.
