The Treaty of Yandabo ( ) was the peace treaty that ended the First Anglo-Burmese War. The treaty was signed on 24February 1826, nearly two years after the war formally broke out on 5March 1824, by General Sir Archibald Campbell on the British side, and the Governor of Legaing Maha Min Hla Kyaw Htin from the Burmese side, without any due permission and consent of the Ahom kingdom, Kachari kingdom or the other territories covered in the treaty. With the British army at Yandabo village, only from the capital Ava, the Burmese were forced to accept the British terms without discussion. According to the treaty, the Burmese agreed to: Cede to the British- Assam, Manipur, Rakhine (Arakan), and the Taninthayi (Tenasserim) coast south of the Salween River. Cease all interference in Cachar region of Assam and the Jaintia Hills district. Pay an indemnity of one million pounds sterling in four installments. Allow an exchange of diplomatic representatives between Ava and Calcutta. Sign a commercial treaty in due course. The treaty ended the longest and most expensive war in British Indian history.

The campaign cost the British five million pounds sterling (roughly 18.5 billion in 2006 dollars) to 13 million pounds sterling; this expenditure led to a severe economic crisis in British India in 1833. For the Burmese, it was to be the beginning of the end of their independence. The Third Burmese Empire, briefly the terror of British India, was effectively undone, crippled and no longer a threat to the eastern frontier of British India. The Burmese would be crushed for years to come by repaying the huge indemnity of one million pounds (then US$5 million), a large sum even in Europe at that time. The British would wage two more wars against the much weaker Burmese, and swallow up the entire country by 1885. Initial negotiations The British were already in a commanding position when initial peace negotiations were commenced in September 1825 in Ngagyaungbinzeik, 20 miles north of Pyay (Prome). After their victory at the Battle of Danubyu in April 1825 that killed Burmese commander-in-chief Gen. Maha Bandula, the British consolidated their gains in Lower Burma, Rakhine and Taninthayi coasts as well as in Assam and Manipur. The British demanded that the Burmese recognize independence and "desist from interference with
