Thonburi Kingdom
The Burmese–Siamese War (1775–1776) was a major military conflict between the Konbaung Dynasty of Burma (Myanmar) and the Thonburi Kingdom of Siam (Thailand). After the fall of Ayutthaya 8 years prior, King Taksin and his followers had rebuilt Siam by reunifying the breakaway states succeeding the fall of Ayutthaya. The Burmese invasion forces faced tough heavy resistance from the Siamese forces and finally withdrew the invasion when King Hsinbyushin died on 10 June 1776. As a result, the Burmese loss of southern Lan Na (Chiang Mai) later proved to be the end of their 200 year rule.
