Through Middle East, World War I and World War II

The role of the United Kingdom in the formal administration of the Kingdom of Iraq was ended in 1932, following the Anglo-Iraqi Treaty of 1930. Then officially a fully independent kingdom, it underwent a period of turbulence under its Hashemite rulers throughout its entire existence. Establishment of Sunni Islam 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 kingdom, 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.

During the World War II, the Iraqi government of the Prince-Regent, Abd al-Ilah, was overthrown in 1941 by the Golden Square officers, headed by Rashid Ali. The short-lived pro-Nazi government of Iraq was defeated in May 1941 by the Allied forces in the Anglo-Iraqi War. Iraq was later used as a base for Allied attacks on the Vichy French-held Mandate of Syria and support for the Anglo-Soviet invasion of Iran. At the same time, the Kurdish leader Mustafa Barzani led a rebellion against the central government in Baghdad. After the failure of the uprising, Barzani and his followers fled to the Soviet Union.

In 1945, during the final stages of World War II, Iraq joined the United Nations and became a founding member of the Arab League. In 1948, massive violent protests, known as the Al-Wathbah uprising, broke out across Baghdad as a popular demand against the government treaty with the British, and with support from the communists. More protests continued in the spring, but were interrupted in May, when martial law was imposed after Iraq entered the 1948 Arab–Israeli War with other members of the Arab League.

In February 1958, King Hussein of Jordan and Prince Abd al-Ilah proposed a union of Hashemite monarchies to counter the recently formed Egyptian–Syrian union. The resulting Arab Federation, formed on 14 February 1958, was short-lived and ended the same year with a military coup led by Abdul-Karim Qasim deposing the monarchy.

Kingdom of Iraq under de facto British administration

The territory of Iraq was under Ottoman dominance until the end of the First World War, becoming an occupied territory under the British military from 1918. In order to transform the region to civil rule, Mandatory Mesopotamia was proposed as a League of Nations Class A mandate under Article 22 and entrusted to the United Kingdom of Great Britain and Ireland, when the former territories of that Ottoman Empire were divided in August 1920 by the Treaty of Sèvres. However, the 1920 Iraqi revolt resulted in the scrapping of the original mandate plan. Instead, the Kingdom of Iraq was recognised as a sovereign country under King Faisal I of Iraq. Not withstanding the formal sovereignty of the Iraqi king, a treaty of alliance was concluded between the Kingdom of Iraq and the United Kingdom in 1922 called the Anglo-Iraqi Treaty. It provided the United Kingdom with a role in the administration and governance of Iraq. King Faisal had previously been proclaimed King of Syria by a Syrian National Congress in Damascus in March 1920 but was ejected by the French in July of the same year. The British RAF retained certain military control. In this manner, Iraq remained under de facto British administration until 1932.

Under King Faisal of Iraq, the civil government of postwar Iraq was led by the High Commissioner, Sir Percy Cox, and his deputy, Colonel Arnold Wilson. British reprisals after the murder of a British officer in Najaf failed to restore order. British administration had yet to be established in the mountains of north Iraq. The most striking problem facing the British was the growing anger of the nationalists in the Iraqi kingdom.
