About this Holiday
Constitution Day, observed on December 10th, commemorates the promulgation of Thailand's first permanent constitution on December 10, 1932, by King Prajadhipok (Rama VII) following the transition from absolute to constitutional monarchy. The 1932 democratic revolution, led by the Khana Ratsadon (People's Party), transformed Thailand's system of governance and established the framework for democratic rule under a constitutional monarchy. Celebrations include official government ceremonies, events at parliament, and public educational activities on democratic values.
