Thai Kingship
Thai rulers were absolute monarchs whose office was partly religious in nature. They derived their authority from the ideal qualities they were believed to possess. The king was the moral model, who personified the virtue of his people, and his country lived at peace and prospered because of his meritorious actions. At Sukhothai, where Ramkhamhaeng was said to hear the petition of any subject who rang the bell at the palace gate to summon him, the king was revered as a father by his people. But the paternal aspects of kingship disappeared at Ayutthaya, where, under Khmer influence, the monarchy withdrew behind a wall of taboos and rituals. The king was considered chakkraphat, the Sanskrit-Pali term for the "wheel-rolling" universal prince who through his adherence to the law made all the world revolve around him.
As the Hindu god Shiva was "lord of the universe," the Thai king also became by analogy "lord of the land," distinguished in his appearance and bearing from his subjects. According to the elaborate court etiquette, even a special language, Phasa Ratchasap, was used to communicate with or about royalty.
