Gambhir Singh’s Death Anniversary is observed in Manipur, India, every January 9. This public holiday honors Raja Gambhir Singh, a significant ruler of Manipur, who played a crucial role in liberating the region from Burmese control during the First Anglo-Burmese War. Born Chinglen Nongdrenkhomba in 1788, he became king in 1821 but faced immediate challenges, including an invasion by the Burmese Army. After fleeing to the neighboring kingdom of Cachar and later negotiating with the British, he was reinstated as ruler following a British victory in 1826. His contributions to defending the rights of the local Hindu community and restoring Manipur's sovereignty are commemorated through memorial ceremonies and various events throughout the state on this anniversary.
