Taksin (originally named '' Sin '') was born in 1733. His father was a Chinese migrant from China named Haihong of the Teochiu ethnic group and his mother was a Thai called Nok Lang. The chronicles tell us that originally Sin was a trader who later, in recognition of services he had rendered, was appointed Governor of Tak Province. In 1765, '' Phraya Tak '' as he was then called, came to Ayutthaya to help defend the city from the burmese. In recognition of his work he was promoted to the title and rank of Phraya Wachira Prakan, Governor of Kamphaeng Phet. Kamphaeng Phet was a fortified out post city.
