英屬緬甸
Most of the early history of Kengtung is made up of myths and legends. At the time of British rule in Burma the Tai Yai people were the majority of the population in Kengtung state with other groups such as Akha and Lahu, forming sizeable communities. According to Wa tradition, in the distant past the territory had belonged to the Wa people who were displaced around 1229 and were later defeated by King Mangrai. The Wa now form a minority of only about 10% in Kengtung State despite having been —according to their myths— the original inhabitants.
