image ranged from that of an anti-monarchist democrat to a republican. The branding of Pridi as a communist and a mastermind of King Ananda's death has since been regarded as politically motivated, which his opponents continued to use even after his death. However, Pridi won every libel lawsuit in Thailand filed against those who promoted such views. He became a symbol of resistance against military dictatorships, as well as a symbol of liberalism, and Thammasat University. The centenary of his birth was celebrated by UNESCO in 2000. Family Pridi wrote that his great-great-great-grandfather, Heng, was a native of Etang Village in the Chenghai County of Guangdong Province, southern China, who came to Siam during the reign of Boromaracha V (Ekkathat) (r. 17581767), leaving behind his wife, who was pregnant with their son, Seng. Heng lived in Siam among the Chinese relatives of King Taksin, who recruited some of the local Chinese, including Heng, to fight against the Burmese invaders in 1767.

Their son, Nai Koet, married Khum, daughter of a wealthy Chinese entrepreneur. When Nai Koet died, his wife directed that his remains were to be cremated and interred at the shrine at Phanomyong Hill, which is the origin of their Thai surname.
