Constitution Day is observed in Cambodia every September 24, commemorating the re-coronation of King Norodom Sihanouk and the adoption of the Cambodian Constitution in 1993. This national holiday marks the day when the new constitution was promulgated, establishing a constitutional monarchy and elevating Sihanouk from former prince to king. The historical significance of this day is rooted in Cambodia's tumultuous past, including Sihanouk's initial crowning in 1941, his abdication in 1955, and the civil war instigated by the Khmer Rouge in 1967. Following the war and a transitional period in the early 1990s, Sihanouk was reinstated, leading to the elections that resulted in the new constitution. Celebrations typically involve national ceremonies and reflections on Cambodia's journey to democracy.
