Answer
Taksin's reign came to an abrupt end through a palace coup d'etat, masterminded by a faction of his high-ranking military officers. Deeply suspicious of his closest aides and increasingly paranoid, Taksin had alienated many of his former allies, making him vulnerable to a sudden power grab. The successful coup resulted in his dethronement and execution, marking a dramatic turning point in the history of the Thonburi Kingdom.
