Big wars and political upheavals often dominate history books in the U.S., while mass hunger crises that killed millions get far less space. That gap is especially clear in several famines across India, China, Iran, and Nigeria that historians, the United Nations, and peer-reviewed research have documented in stark numbers.
5 famine disasters that killed millions
The Great Chinese Famine of 1959 to 1961 remains one of the deadliest hunger disasters ever recorded. Scholars including Yang Jisheng and demographers cited by Britannica have estimated deaths at roughly 15 million to 30 million, with some estimates reaching 45 million, during Mao Zedong’s Great Leap Forward.
The Bengal famine of 1943 killed about 2 million to 3 million people in British India, according to research by economist Amartya Sen and records cited by the Britannica and the Imperial War Museums. The crisis hit Bengal, now split between India and Bangladesh, during World War II under British colonial rule.
India’s Deccan famine of 1630 to 1632 and the Chalisa famine of 1783 to 1784 also caused mass death on a huge scale. Encyclopaedia Britannica estimates about 2 million deaths in the Deccan famine and roughly 11 million during the Chalisa famine across northern India, where crop failures and conflict worsened food shortages.
What happened in India, Iran, and Nigeria
The Persian famine of 1917 to 1919, centered in Iran during World War I, is less widely discussed in U.S. classrooms than the war itself. Historian Mohammad Gholi Majd estimated deaths at 8 million to 10 million, although other scholars have disputed the upper range and said the exact toll remains unconfirmed.
In Nigeria, the famine tied to the Biafran war from 1967 to 1970 became one of the defining humanitarian crises of the late 1960s. The International Committee of the Red Cross and later historical accounts reported that starvation and disease killed more than 1 million people, many of them children, in the secessionist region of Biafra.
What is firmly established is the scale of civilian suffering in each case. What is less certain in some famines, especially Iran in 1917 to 1919, is the exact death total, because wartime disruption, weak census data, and disputed archives have left historians with a wide range of estimates.
Why these famines still matter now
Historians have tied these famines to a mix of drought, war, colonial policy, forced procurement, transport failures, and political decisions rather than food scarcity alone. Amartya Sen argued in his 1981 book Poverty and Famines that distribution failures and loss of access to food, not just low harvests, were central in cases like Bengal.
That context matters because famine history is also a record of government power and who gets protected in a crisis. The UN Food and Agriculture Organization has repeatedly said modern hunger disasters are often driven by conflict, inflation, and disrupted markets, factors that also appeared in 1943 Bengal and 1967 Biafra.
For readers in the U.S., these events are less a list of distant tragedies than part of a broader history of how policy choices can shape who eats and who does not. The historical record, from British India in 1943 to China in 1961, shows that famine is rarely just a weather story.
