Though Iran was officially neutral when war broke out in 1939, many Iranians were sympathetic towards Germany which, they hoped, might liberate them from years of British and Russian oppression. An increasing German presence combined with British concern for continued supplies of Iranian oil led to Operation Countenance, an Allied invasion launched on 25 August 1941. As a result Reza Shah was deposed and replaced by his son Mohammad Reza Pahlavi. Iran was forced to abandon its neutral position though it did not actually declare war against Germany until September 1943. From 1941 onwards, British propaganda, published by the Ministry of Information (MOI), played a crucial role. Favouring a cultural approach, the MOI produced items such as the Shāhnāmah cartoons by the artist Kem (see our post ‘The Shahnameh as propaganda for World War II’) and the magazine Rūzgār-i naw, or The New Age which was published quarterly in Persian between 1941 and 1946.
