The Hmong, also known as the Miao, are an Indigenous People from the mountainous regions of China, Vietnam, Laos, and Thailand.
The Hmong’s current population is estimated at 4-5 million people.
A number of Hmong people fought against the communist-nationalist Pathet Lao during the Laotian Civil War. Hmong people were singled out for retribution when the Pathet Lao took over the Laotian government in 1975, and tens of thousands fled to Thailand seeking political asylum. Thousands of these refugees have resettled in Western countries since the late 1970s, mostly the United States but also Australia, France, French Guiana, and Canada. Others have been returned to Laos under United Nations-sponsored repatriation programs. Around 8,000 Hmong refugees remain in Thailand.
