Treaty of Yandabo

February 24, 1826

Ending the First Anglo-Burmese War, this Burmese surrender ceded Assam, Manipur, Arakan, and Tenasserim to the British and imposed a crushing indemnity. It was one of the longest and most expensive wars the East India Company had yet fought. The kingdom of Ava's frontiers had shrunk forever, and British India had a Bay of Bengal shoreline.
