History of Myanmar
Account of past events in the Burmese civilisation
The history of Myanmar covers the period from the time of first-known human settlements 13,000 years ago to the present day. The earliest inhabitants of recorded history were a Tibeto-Burman-speaking people who established the Pyu city-states ranged as far south as Pyay and adopted Theravada Buddhism. Another group, the Bamar people, entered the upper Irrawaddy valley in the early 9th century. They went on to establish the Pagan Kingdom, the first-ever unification of the Irrawaddy valley and its periphery. The Burmese language and culture slowly came to replace Pyu norms during this period. After the First Mongol invasion of Burma in 1287, several small kingdoms, of which the Kingdom of Ava, the Hanthawaddy Kingdom, the Kingdom of Mrauk U and the Shan States were principal powers, came to dominate the landscape, replete with ever-shifting alliances and constant wars.
