Background
Prince Phon (Thai: พร) was the son of Phra Chao Suea.
Prince Phon (Thai: พร) was the son of Phra Chao Suea.
His reign was the last blooming period of Ayutthaya as the kingdom would fall nine years after his death. Phon was then appointed as the Front Palace. In 1732, Thai Sa died and a civil war commenced.
The civil war within Ayutthaya was "a big fight, bigger than any which had occurred in Siam in former times".
Because the Samuha Kalahom had lent the support to Prince Aphai, Borommakot removed the power of Samuha Kalahom by depriving its authorities over southern Siam and transferred the power to Kromma Tha instead. The Samuha Kalahom remained as a mere military figurehead.
Thammathibet proved to be an able prince and was a poet. However, Thammathibet had affairs with two of Borommakot"s concubines, Princess Sangwan and Princess Nim - a severe crime.
The lovers were caught in 1746 and the three were beaten.
The Front Palace was lashed 120 stokes and the two concubines 30 each. The Front Palace died while he was beaten and Princess Sangwan died 3 days later. Princess Nim survived, but she was banished from the court.
However, Ekkathat still had designs on the throne, and the subsequent struggles of the princes for the throne would contribute to the fall of Ayutthaya in 1767, during the reign of Ekkathat.
