Srisimha

Śrīsiṃha (Thai: ศรีสิงห์) was an 11th-century Siamese monarch recorded in the Ayutthaya Testimonies as the ruler of Phetchaburi and Phraek Si Racha. At the age of 15, he ascended the throne at Phetchaburi following the death of his father, King Vijayaraja. However, following a prophecy delivered by the royal astrologer, he later transferred the royal capital northward to Phraek Si Racha. This relocation likely took place subsequent to the conclusion of the protracted conflict between Adityadhammikarāja of Haripuñjaya and Lāvarāja of Lavo, following which Adityadhammikarāja successfully installed his younger brother, Chandrachota, as the new monarch of Lavo in 1052 CE.

Śrīsiṃha was born to Queen Śrīkanyārājadevī (ศิริกัญญาราชเทวี), a consort of King Vijayaraja and a descendant of the Padumasūriyavaṃśa dynasty. He had two principal consorts. The first, Queen Suchāvatīdevī (สุชาวดีเทวี), bore two sons: Jyeṣṭhakumāra (เชษฐกุมาร), who died in early childhood, and Surindraraja. The second consort, Queen Suvaṇṇapabbata (สุวรรณบัพพตา), likewise bore two sons, Sūryavaṃśa and Anurāja.

Śrīsiṃha is said to have reigned for 35 years and died at the age of 50. He was succeeded by his eldest surviving son, King Surindraraja, who subsequently founded the city of Chai Nat and established it as his new royal seat.
