The monarchy of Thailand is the constitutional form of government of Thailand (formerly Siam). The king of Thailand (Thai: พระมหากษัตริย์ไทย, historically, king of Siam; Thai: พระเจ้ากรุงสยาม) is the head of state and head of the ruling Royal House of Chakri.
Although the current Chakri dynasty was created in 1782, the existence of the institution of monarchy in Thailand is traditionally considered to have its roots in the founding of the Sukhothai Kingdom in 1238, with a brief interregnum from the death of Ekkathat to the accession of Taksin in the 18th century. The institution was transformed into a constitutional monarchy in 1932 after the bloodless Siamese Revolution of 1932. The monarchy’s official ceremonial residence is the Grand Palace in Bangkok, while the private residence has been at the Dusit Palace. The king of Thailand is head of state, head of the Royal Thai Armed Forces, adherent of Buddhism and upholder of religions.
