The King of Thailand, King Bhumibol Adulyadej (or Rama IX), is the world's longest reigning monarch. He has reigned since 1946. The constitution stipulates that although the sovereignty of the state is vested in the people, the king will exercise such powers through the three branches of the Thai government. Under the constitution the king is given very little power, but remains a figurehead and symbol of the Thai nation. As the head of state, however, he is given some powers and has a role to play in the workings of government. According to the constitution, the king is head of the armed forces. He is required to be Buddhist as well as the defender of all faiths in the country. The king also retained some traditional powers such as the power to appoint his heirs, the power to grant pardons, and the royal assent. The king is aided in his duties by the Privy Council of Thailand.
The king is head of the House of Chakri, the ruling house of Thailand founded by King Buddha Yodfa Chulaloke (or Rama I) in 1782. The monarchy and the royal family commands huge respect in Thailand. The present monarch has a great deal of popular respect and moral authority, which has been used at times to resolve political crises. The monarch's official home is the Grand Palace, however the present king lives primarily in the Chitralada Palace in Bangkok or the Klai Kangwon Villa, in Hua Hin. The monarch's household is managed by the Bureau of the Royal Household and his finances by the Crown Property Bureau.
The heir to the throne is the Crown Prince of Thailand, Prince Maha Vajiralongkorn. The succession to the throne is governed by the 1924 Palace Law of Succession, promulgated by King Vajiravudh. Palace law follows the male agnatic primogeniture, where males are only allowed to succeed and inheritance is passed only from father to son and through male line only.[citation needed]
