Thaton Kingdom  The Thaton Kingdom, Suwarnabhumi, or Thuwunnabumi ( or ) was a Mon kingdom, believed to have existed in Lower Burma from at least the 4th century BC to the middle of the 11th century AD. One of many Mon kingdoms that existed in modern-day Lower Burma and Thailand, the kingdom was essentially a city-state centered on the city of Thaton. It traded directly with South India and Sri Lanka, and became a primary center of Theravada Buddhism in South-East Asia. Thaton, like other Mon kingdoms, faced the gradual encroachment of the Khmer Empire. But it was the Pagan Kingdom from the north that conquered the fabled kingdom in 1057. Mon tradition maintains that the kingdom was called Suvannabhumi (), a name also claimed by Lower Thailand, and that it was founded during the time of the Buddha in the 6th century BCE. Thaton is the Burmese name of Sadhuim in Mon, which in turn is from Sudhammapura in Pali, after Sudharma, the moot hall of the gods. According to the Mon tradition, the Kingdom of Thaton was founded during the time of the Buddha, and was ruled by a dynasty of 59 kings. The tradition also maintains that a group of political refugees founded the city of Pegu (Bago) in 573. But the historical kingdom probably came into existence some time in the 9th century, following the entry Mon people into Lower Burma from modern northern Thailand. GE Harvey's History of Burma, citing the Shwemawdaw Thamaing, gives the year of founding of Pegu as 825; even that date remains unattested. Indeed, the earliest mention of Pegu is 1266, in Old Burmese. Traditional Burmese and Mon reconstructions hold that Thaton was overrun by the Pagan Kingdom from Upper Burma in 1057. King Anawrahta, having been converted to Theravada Buddhism by a Mon monk, Shin Arahan, reportedly asked for the Theravada Buddhist canon from King Manuha of Thaton. The Mon king's refusal was used by Anawrahta as a pretense to invade and conquer the Mon kingdom, whose literary and religious traditions helped to mold early Pagan civilization. According to the chronicles, King Manuha of Thaton surrendered after a 3-month siege of the city by Pagan's forces on 17 May 1057 (11th waxing of Nayon, 419 ME).
