Phimai regime
Origins
When the Ayutthaya Kingdom fell to the Burmese in 1767, its provincial governors and princes set up rival regimes. At Phimai, on the Khorat plateau, Prince Thepphiphit, a son of King Borommakot who had earlier been exiled to Ceylon, gathered followers and claimed authority as the legitimate heir.
Rule and society
The regime controlled the north-eastern plateau around Phimai and Nakhon Ratchasima, a region with old Khmer temples and Lao and Khmer populations. Its power rested on Thepphiphit's royal prestige and local nobles. It was one of five main contenders for the Siamese succession.
Decline and legacy
In 1768 Taksin of the Thonburi Kingdom attacked Phimai and defeated its forces. Thepphiphit was captured and executed, and the plateau was brought under Thonburi rule.
