In the aftermath of World War I, the territories of North Africa and the Mideast were in turmoil. Armed insurgency in modern Iraq by nationalists who wanted to remove British control of the region, led to concessions by the British, who essentially installed Faisal ibn Husayn as King of Iraq, confident that he was controllable. British forces remained in Iraq, and British troops created, trained, and armed an Iraqi army. In 1930, a second treaty was negotiated which established mutual defense between the British Empire and the Kingdom of Iraq. In 1932, Iraq became fully independent, remaining so until the 1958 revolution.
