The Captivity of Mangalorean Catholics at Seringapatam (1784–1799) was a 15-year imprisonment of Mangalorean Catholics and other Christians at Seringapatam in the Indian region of Canara by Tipu Sultan, the de facto ruler of the Kingdom of Mysore. Estimates of the number of captives range from 30,000 to 80,000 but the generally accepted figure is 60,000, as stated by Tipu in the Sultan-ul-Tawarikh. The captivity was the most disconsolate period in the community's history. Its cause is disputed, although most historians consider it happened for political rather than religious reasons, owing to the alliance between the Mangalorean Catholics and the British during the Second Anglo-Mysore War (1780–1784).
