Thai political history has been shaped by a series of significant events, including the establishment of the Sukhothai Kingdom in the 13th century and the later Ayutthaya Kingdom. In the 20th century, Thailand transitioned from an absolute monarchy to a constitutional monarchy, with the first constitution enacted in 1932. The political landscape has been marked by military coups, with notable events in 1947, 1958, and 2006. The rise of political parties, such as the Pheu Thai Party and Democrat Party, has led to ongoing struggles between different factions, influencing the country's governance and stability.
