Shan people
The Shan people have inhabited the Shan Hills and other parts of northern modern-day Burma as far back as the 10th century AD. The Shan kingdom of Mong Mao (Muang Mao) existed in Yunnan as early as the 10th century CE but became a Burmese vassal state during the reign of King Anawrahta of Pagan (1044–1077).
