East India Company defends Assam (ruled by Ahoms) from Burmese attacks and plants the seeds for incorporation of Burma to British ruled India in 19th century.

Subsequent wars further weakened Burmese sovereignty. The Second Anglo-Burmese War (1852–1853) led to the British annexation of Lower Burma for its valuable resources. The Third Anglo-Burmese War in 1885 resulted in the full annexation of Burma, which was formally incorporated as a part of British India by January 1886. The colonial administration ruled Burma as part of British India until 1937, after which Burma was made a separate colony. British rule lasted until Burma’s independence in 1948.
