On 8 April 1767, the Ayutthaya Kingdom, a major power in Southeast Asia for over four centuries, fell to invading Burmese forces after a brutal siege.
The capital city of Ayutthaya, in present-day Thailand, was sacked and burned, marking the end of the kingdom’s dominance.
The invasion led to widespread devastation, the collapse of central authority, and mass displacement, but it also paved the way for the rise of the Thonburi Kingdom under General Taksin, who later reunified much of Siam.
