Populations have dwelled in Chiang Rai since the 7th century and it became the center of the Lanna Thai Kingdom during the 13th century. The region, rich in natural resources and textiles, was occupied by the Burmese until 1786.
Chiang Rai became a province in 1910, after being part of the kingdom of Lannathai for centuries. After Lannathai was incorporated into Thailand, it stayed an autonomous region and thus the Chiang Rai area was administered from Chiang Mai.
Chiang Rai province's Golden Triangle bordering Laos and Burma was once the hub of opium production which had much influence on cultural practices and lifestyles. Until this day, entire clans live together in bamboo houses and each village has its own individual character.
