The Persian famine of 1917–1919 was a period of widespread mass starvation and disease in Persia (Iran) under the rule of the Qajar dynasty during World War I. The famine took place in the territory of Iran, which despite declaring neutrality was occupied by the forces of British, Russian and Ottoman empires whose occupation contributed to the famine. The number of people who died between 1917 and 1919 because of hunger and from diseases, which included cholera, plague and typhus, as well as influenza infected by 1918 flu pandemic, has been variously given at 2 million, 6 million, and 8-10 million. A variety of factors are commented to have caused and contributed to the famine, including successive seasonal droughts, requisitioning and confiscation of foodstuffs by occupying armies, speculation, hoarding, war profiteering, and poor harvests.
