The captivity of Nairs at Seringapatam was imposed on the Nairs of Malabar by Tipu Sultan, the de facto ruler of the Kingdom of Mysore from 1786 to 1799. They were subjected to forcible conversions to Sunni Islam, the official religious sect sanctioned by the Ottoman Caliphate, whose approval and alliance was sought by Tippu Sultan.[1][2][3][4][5] Those who refused conversions had to face many humiliations, hardships, torture, and even death.[6][7] The Nairs were treated with extreme brutality due to their strong adherence to the Hindu faith and martial tradition.[8][9][10] The captivity ended when Nair troops from Travancore defeated Tipu in the Third Anglo-Mysore War.[11][12] It is estimated that out of the 30,000 Nairs put to captivity (including women and children), only a few hundred returned to Malabar alive.[12][13]
North Malabar was divided into the Nair principalities of Chirakkal, Kadattanad, Kottayam, Kurangod and the Moplah principality of Cannanore which owed nominal allegiance to Chirakkal. South Malabar was divided between the Zamorin of Calicut and the Raja of Cochin.[14]
