à Ârësiá¹Âha () 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 AdityadhammikarÃÂja of Haripuñjaya and LÃÂvarÃÂja of Lavo, following which AdityadhammikarÃÂja successfully installed his younger brother, Chandrachota, as the new monarch of Lavo in 1052 CE.
à Ârësiá¹Âha was born to Queen à ÂrëkanyÃÂrÃÂjadevë (), a consort of King Vijayaraja and a descendant of the Padumasà «riyavaá¹Âà Âa dynasty. He had two principal consorts. The first, Queen SuchÃÂvatëdevë (), bore two sons: Jyeá¹£á¹ÂhakumÃÂra (), who died in early childhood, and Surindraraja. The second consort, Queen Suvaá¹Âá¹Âapabbata (), likewise bore two sons, Sà «ryavaá¹Âà Âa and AnurÃÂja.
à Ârësiá¹Âha 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.
