What is "borommakot"

Borommakot or Borommarachathirat III 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.
