What is "pyinbya"

Pyinbya (, ; 817–876) was the king of Pagan Dynasty of Burma (Myanmar) who founded the city of Pagan (Bagan) in 849 CE. Though the Burmese chronicles describe him as the 33rd king of the dynasty founded in early 2nd century CE, modern historians consider Pyinbya one of the first kings of Pagan, which would gradually take over present-day central Burma in the next two hundred years. He was the paternal great-grandfather of King Anawrahta, the founder of Pagan Empire.
