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.
Chronicle tradition.
According to the Burmese chronicles, the future king was born to King Saw Khin Hnit of Pagan. He was born in either 817 CE (or 802 CE). He was lord of Pyinbya village of Pagan prior to his accession, and known as Pyinbya Mintha. He succeeded his brother King Khelu as king in 846 CE. He founded the city of Pagan on 23 December 849 (6th waxing of Pyatho 211 ME). He also founded a settlement of Taungdwin in 857, perhaps the southernmost limit of his nascent kingdom. He died in 876 CE at age 59 (in his 60th year). (Note that main Burmese chronicles do not agree on his regnal years or birth and death years. The oldest chronicle "Zatadawbon Yazawin" is considered to be the most accurate for the Pagan period.) The table below lists the dates given by four main chronicles, as well as Hmannan's dates when anchored by the Anawrahta's inscriptionally verified accession date of 1044.
Pyinbya was succeeded by his son Tannet.
Scholarship views.
According to mainstream scholarship, Pyinbya is one of the earliest kings of Pagan, founded by the Mranma (Bamar / Burmans) of the Nanzhao Kingdom. Pagan is the first known Burman settlement in the Irrawaddy valley, following the devastating raids into upper Irrawaddy valley by Nanzhao that lasted from the 750s to the 830s. After the attacks, which left the Pyu states severely weakened, large numbers of Mranma warriors of Nanzhao and their families remained in the upper Irrawaddy valley. Pagan was founded as a fortified settlement along a bend in the Irrawaddy river. The new settlement may have been designed to help the Nanzhao pacify the surrounding countryside. It was a certainly a strategic spot, close to the Chindwin river and just to the west of a richly irrigated rice plain.
Pagan was one of several competing city-states until the late 10th century when it grew in authority and grandeur. Two hundred years after Pyinbya founded Pagan, his great-grandson Anawrahta went on to create the Pagan Empire, the first ever unification of the Irrawaddy valley and its periphery.
