Burmese Forces Sack and Destroy Ayutthaya

On April 7, 1767, after a fourteen-month siege, Burmese forces under King Hsinbyushin captured and destroyed Ayutthaya, the capital of the Thai kingdom for 417 years. Soldiers burned temples, palaces, and libraries, melted gold from religious statues, and killed or deported much of the population. The destruction obliterated centuries of royal archives, art, and literary works. The kingdom fragmented until Taksin reunified the Thai polities and established a new capital downriver, eventually relocated to Bangkok. The fall of Ayutthaya remains the defining trauma of Thai national memory and directly explains the founding of the modern Thai capital.
