The Malabar rebellion of 1921 (also called Moplah rebellion, and Mappila rebellion, Malayalam: malabār kalāpam) started as a resistance against the British colonial rule in Malabar region of Kerala. The popular uprising was also against the prevailing feudal system controlled by elite Hindus. For many, the rebellion was primarily a peasant revolt against the colonial government. During the uprising, the rebels attacked various symbols and institutions of the colonial state, such as telegraph lines, train stations, courts and post offices. There were also a series of clashes between the Mappila peasantry and their landlords, the latter supported by the British colonial government, throughout the 19th and early 20th centuries. The heavy-handed suppression of the Khilafat Movement by the colonial government was met by resistance in the Eranad and Valluvanad taluks of Malabar. The Mappilas attacked and took control of police stations, colonial government offices, courts and government treasuries. For six months from August 1921, the rebellion extended over – some 40% of the South Malabar region of the Madras Presidency. The British colonial government sent troops to quell the rebellion and martial law imposed. An estimated 10,000 people died, although official figures put the numbers at 2337 rebels killed, 1652 injured and 45,404 imprisoned. Unofficial estimates put the number imprisoned at almost 50,000 of whom 20,000 were deported, mainly to the penal colony in the Andaman Islands, while around 10,000 went missing. According to Arya Samaj about 600 Hindus were killed and 2,500 were forcibly converted to Islam during the rebellion. Contemporary colonial administrators and modern historians differ markedly in their assessment of the incident, debating whether the revolts were triggered by religious fanaticism or agrarian grievances. At the time, the Indian National Congress repudiated the movement and it remained isolated from the wider nationalist movement.
