The first recorded kingdom attributed to the Mon people is Dvaravati,[1] which prospered until around 1000 CE when their capital was ruled by the Khmer Empire and a significant portion of the inhabitants fled west to present-day Lower Burma and eventually founded new polities.
[2] According to colonial period scholarship, the Mon established small polities (or large city-states) in Lower Burma in the 9th century.
[3] Between 1050 and about 1085, Mon craftsmen and artisans helped to build some two thousand monuments at Pagan, the remains of which today rival the splendors of Angkor Wat.
[5] However, research from the 2000s—still a minority view—argues that Mon influence on the interior after Anawrahta's conquest is a greatly exaggerated post-Pagan legend, and that Lower Burma in fact lacked a substantial independent polity prior to Pagan's expansion.
[7] Though the size and importance of these states are still debated, all scholars accept that during the 11th century, Pagan established its authority in Lower Burma and this conquest facilitated growing cultural exchange, if not with local Mon, then with India and with Theravada stronghold Sri Lanka.
A more centralised rule came with the reign of King Razadarit, who not only firmly unified the three Mon-speaking regions together but also successfully fended off the northern Burmese-speaking Kingdom of Ava in the Forty Years' War (1385–1424).
After Hanthawaddy's second invasion of Upper Burma failed in May 1754, the kingdom's leadership in self-defeating measures killed off the Toungoo royal family, and persecuted ethnic Burmans in the south, both of which only strengthened Alaungpaya's hand.
Konbaung forces captured the Irrawaddy delta in May 1755, the French defended port of Thanlyin in July 1756, and finally the capital Pegu in May 1757.
[12] By the early 19th century, assimilation, inter-marriage, and mass migration of Burman families from the north had reduced the Mon population to a small minority.
