Sà «ryavaá¹Âà Âa () was a 12th-century Siamese monarch recorded in the Ayutthaya Testimonies as the ruler of Mueang Phraek, whose political center was located at Chai Nat. He was the elder son of Suvaá¹Âá¹Âapabbata (), the second queen consort of King Srisimha. Upon the death of his half-brother Surindraraja, the son of the first queen consort SuchÃÂvatëdevë (), Sà «ryavaá¹Âà Âa ascended the throne at the age of 25. His reign, which endured for 32 years, ultimately came to an end when he was overthrown by his younger brother, Anuraja.
According to the same source, Sà «ryavaá¹Âà Âa was married to Queen Padmavatë (), who later engaged in an illicit affair with Prince Anuraja. The two subsequently eloped, an act that provoked the king's profound indignation. In retaliation, Sà «ryavaá¹Âà Âa ordered AnurajaâÂÂs arrest; however, the attempt was unsuccessful. In the aftermath, Anuraja is said to have raised a military force, launched a campaign against Sà «ryavaá¹Âà Âa, and ultimately seized the throne. Following his victory, AnurÃÂja founded a new royal city named Siá¹Âhapurë () and established it as a new capital.
