شيخ الإسلام
Chularatchamontri (จุฬาราชมนตรี) is the title of Shaykh al-Islām in Thailand. The title was first used in the Ayutthaya Kingdom when King Songtham (1611–1628) appointed Sheikh Ahmad to the office. Pursuant to the current Islamic Organ Administration Act, BE 2540 (1997), Chularatchamontri is appointed by the king upon advice of the prime minister. He has the authority to administer all Islamic affairs in the nation and to provide advice on Islamic affairs to governmental agencies. Chularatchamontri vacates his office upon death, resignation and removal by the king upon the advice of the prime minister.
