Thonburi Kingdom
After the collapse of Taksin's Thonburi Kingdom, Phraya Chakri founded the Chakri Dynasty and ascended the throne in 1782 as Rama I. Rama I was born to Thongdi, a leading Mon nobleman serving the royal court in Ayutthaya in 1737. Rama I's queen consort Amarindra was born to a wealthy Mon family who migrated to Siam in the earlier times. Rama I founded Bangkok City and moved the capital from Thonburi to Bangkok. When a huge wave of Mon migrations from Burma (now Myanmar) to Siam (now Thailand) happened in 1814, his grandson, the Prince Mongkut (later Rama IV) proceeded to welcome the Mon himself at the Siam-Burma border. Mongkut himself and the Chakri dynasty of Thailand today are of partial Mon ancestry.
