Borommakot

Borommakot (Thai: บรมโกศ) or Borommarachathirat III (Thai: บรมราชาธิราชที่ 3) was the king of Ayutthaya from 1733 to 1758. His reign was the last blooming period of Ayutthaya as the kingdom would fall nine years after his death.

"His reign of 25 years is important for being the last peaceful period of Ayudhya during which literature with the arts and crafts flurished." However, the king himself was known for "cruelty to people and animals alike," with seven of his sons meeting violent deaths.

Prince Phon (Thai: พร) was the son of Phra Chao Suea. His elder brother, Prince Phet (เพชร), succeeded the throne as Thai Sa in 1708. Phon was then appointed as the Front Palace. Upon the death of Thai Sa, however, Thai Sa decided to give his throne to his second eldest son, Prince Aphai, since his eldest son had entered the priesthood. In 1732, Thai Sa died and a civil war commenced. Phon led his armies against his nephews, Prince Aphai and Prince Paramet. The civil war within Ayutthaya was "a big fight, bigger than any which had occurred in Siam in former times". With the victory ensured, Phon executed his nephews, the government civil servant allies, and took the throne as King Borommakot.
