The Anglo-Iraqi War was a British-led Allied military campaign during the Second World War against the Kingdom of Iraq, then ruled by Rashid Ali al-Gaylani who had seized power in the 1941 Iraqi coup d'état with assistance from Germany and Italy. The campaign resulted in the downfall of Gaylani's government, the re-occupation of Iraq by the British, and the return to power of the Regent of Iraq, Prince 'Abd al-Ilah, a British ally.
