This day commemorates the proclamation of the constitution on this day in 1993. The country was brought to its knees by the infamous Khmer Rouge regime of Pol Pot in the 1970s, and then followed by the Cambodian-Vietnamese War which lasted until 1991 and the signing of the Paris Peace Agreements in October of that year. An outcome of the agreements was that there would be a new constitution to help transition Cambodia into a modern democratic country with a constitutional monarchy. Prince Sihanouk singed the constitution into law on this day in 1993, formally establishing the Kingdom of Cambodia, and was sworn in as king later that day. It is a public holiday in the country.
