Answer
Thonburi, the new capital city established by Taksin, served as the political and economic center of the Thonburi Kingdom from 1768 to 1782. Located on the west bank of the Chao Phraya River, opposite present-day Bangkok, Thonburi held strategic significance as a trading hub and a defensive stronghold. Taksin's reign marked a crucial period of revitalization and unification for Thailand after the fall of the Ayutthaya Kingdom.
