Emperor Wu of Liang
Bhagadatta was a king of the kingdom of Langkasuka who established contacts with China in the 6th century. It is recorded in the "Book of Liang" that the king "Pojiadaduo" (婆伽達多, believed to be a Chinese transcription of Bhagadatta) sent his envoy "Acheduo" (阿撤多) to the court of Emperor Wu of Liang in 515 to present a memorial. Further missions were sent by Bhagadatta and his successor to the Liang court in 523, 531, and 568.
