Bago, Myanmar
Various Mon language chronicles report widely divergent foundation dates of Bago, ranging from 573 CE to 1152 CE while the "Zabu Kuncha", an early 15th century Burmese administrative treatise, states that Pegu was founded in 1276/77 CE. The earliest extant evidence of Pegu as a place dates only to the late Pagan period (1212 and 1266) when it was still a small town, not even a provincial capital. After the collapse of the Pagan Empire, Bago became part of the breakaway Kingdom of Martaban by the 1290s.
