Rashid Ali al-Gaylani
On 1 April 1941, Rashid Ali al-Gaylani and members of the Golden Square staged a coup d'état and overthrew the government of 'Abd al-Ilah. During the subsequent Anglo-Iraqi War, the United Kingdom (which still maintained air bases in Iraq) invaded Iraq for fear that the Rashid Ali government might cut oil supplies to Western nations because of his links to the Axis powers. The war started on 2 May, and the British, together with loyal Assyrian Levies, defeated the forces of Al-Gaylani, forcing an armistice on 31 May.
