There were three Burmese invasions of Assam between 1817 and 1826, during which time the Kingdom of Assam (Ahom) came under the control of Burma from 1821 to 1825. Locally, this period, called the manor din (Assamese: “The days/period of the Burmese”) by the Indigenous Assamese people is remembered with horror. The sharp drop in population due both to depredations as well emigrations left the erstwhile kingdom in shambles. It was the climactic period of the Ahom kingdom. The British, who were earlier reluctant to colonise Assam, came into direct contact with a belligerent Burmese occupying force. Following the First Anglo-Burmese War they annexed Assam and took Manipur as a subsidiary state.
