History of Myanmar
According to the colonial era scholarship, as early as the 6th century, another people called the Mon began to enter the present-day Lower Burma from the Mon kingdoms of Haribhunjaya and Dvaravati in modern-day Thailand. By the mid 9th century, the Mon had founded at least two small kingdoms (or large city-states) centred around Bago and Thaton. The earliest external reference to a Mon kingdom in Lower Burma was in 844–848 by Arab geographers. But recent research shows that there is no evidence (archaeological or otherwise) to support colonial period conjectures that a Mon-speaking polity existed in Lower Burma until the late 13th century, and the first recorded claim that the kingdom of Thaton existed came only in 1479.
