The Akha are an ethnic group who live in small villages at higher elevations in the mountains of Thailand, Myanmar, Laos and Yunnan Province in China. They made their way from China into Southeast Asia during the early 20th century. Civil war in Burma and Laos resulted in an increased flow of Akha immigrants and there are now 80,000 people living in Thailand's northern provinces of Chiang Rai and Chiang Mai.

Chiang Rai is the northernmost major city in Thailand, with a population of about 200,000 people. It is located in Mueang Chiang Rai District, Chiang Rai Province. Chiang Rai was established as a capital city in the reign of King Mangrai, in 1262 CE.
