King Taksin Memorial Day is observed in Thailand every December 28. This national holiday commemorates the coronation anniversary of King Taksin, who reigned Siam from December 28, 1767, to April 6, 1782. The day celebrates Taksin's efforts in liberating Siam from Burmese occupation and his role in unifying the country. Despite his military focus, he also promoted foreign relations, infrastructure development, and cultural revival. Taksin is remembered as one of Siam's greatest kings, although his later reign was marked by controversy and his eventual deposition by a coup. The holiday serves as a reminder of his complex legacy in Thai history.
