The First Anglo-Burmese War (Burmese: ပထမ အင်္ဂလိပ် မြန်မာ စစ်; [pətʰəma̰ ɪ́ɰ̃ɡəleiʔ mjəmà sɪʔ]; 5 March 1824 – 24 February 1826), also known as the First Burma War, was the first of three wars fought between the British and Burmese empires in the 19th century. The war, which began primarily over the control of Northeastern India, ended in a decisive British victory, giving the British total control of Assam, Manipur, Cachar and Jaintia as well as Arakan Province and Tenasserim. The Burmese submitted to a British demand to pay an indemnity of one million pounds sterling, and signed a commercial treaty.This war was the longest and most expensive war in British Indian history. Fifteen thousand European and Indian soldiers died, together with an unknown number of Burmese military and civilian casualties. The high cost of the campaign to the British, 5–13 million pounds sterling (£400 million – £1.12 billion as of 2020), contributed to a severe economic crisis in British India which cost the East India Company its remaining privileges.Though once strong enough to threaten the interests of the British East India Company (especially with respect to the eastern border regions of Assam, Manipur, and Arakan), the Burmese Empire now suffered "the beginning of the end" of its status as an independent nation. They would be economically burdened for years to come by the cost of the indemnity. The British, eventually waging the Second and Third Anglo-Burmese Wars against a much-weakened Burma, would assume control of the entire country by 1885.
