History of British atrocities in Iran, page-2

The Iranian famine of 1942–1943 refers to a period of major starvation that took place in Iran, which was under the rule of the Pahlavi dynasty. Iran at the time was occupied by the United Kingdom and Soviet Union despite being a neutral country in the Second World War.^[1]

During the occupation, both the British and the Soviets tried to strengthen their influence in their respective zones. The allies took control over the Iranian rail network and contracted half of Iran's publicly- and privately-owned trucks, thus occupying 75 percent of the country's food distribution capacity in the midst of the 1941 harvest. The remaining transportation capacities were quickly rendered unusable because of a restriction of the import of spare parts.

Mohammad Gholi Majd is the only author to have written a book about the famine. In the Journal of Iranian Islamic Period History, Majd concluded that three to four million Iranians—a quarter of the population—died of starvation and disease during the Allied occupation in World War II, citing U.S. State Department population figures for 1941 (15 million) and 1944 (10-12 million)
