Answer
Taksin became the ruler of the Thonburi Kingdom in 1767, founding a new dynasty after the fall of the Ayutthaya Kingdom. He established his capital at Thonburi, across the Chao Phraya River from present-day Bangkok, and successfully defended the kingdom against Burmese invasions. Taksin's reign marked the beginning of a new era in Thai history and laid the foundation for the modern Thai state.
