The Anglo–Iraqi War (2–31 May 1941) was a British military campaign to regain control of Iraq and its major oil fields. Rashid Ali had seized power in 1941 with assistance from Germany. The campaign resulted in the downfall of Ali'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. The British launched a large pro-democracy propaganda campaign in Iraq from 1941–5. It promoted the Brotherhood of Freedom to instil civic pride in disaffected Iraqi youth. The rhetoric demanded internal political reform and warned against growing communist influence. Heavy use was made of the Churchill-Roosevelt Atlantic Charter. However, leftist groups adapted the same rhetoric to demand British withdrawal. Pro-Nazi propaganda was suppressed. The heated combination of democracy propaganda, Iraqi reform movements, and growing demands for British withdrawal and political reform became as a catalyst for postwar political change.
