been distinguished by their traditional dress and include the Tai Dam (Black Tai), Tai Daeng (Red Tai), and Tai Khao (White Tai). The Laos to define both the ethnicity and nationality. Further complication is added by the geopolitical history between Laos and Thailand, there are an estimated 19 million “Lao” speakers living in northeastern Thailand (Thai Isan or Lao Tai) and only 3 million in Laos. As a consequence identity politics has played a major role in the defining the Lao Loum. The Lao government makes no distinction between the bordering groups and views them as sharing a common identity, but the government of Thailand has through a process known as “Thaification” assimilated the Lao living in Isan. The Lao Loum define themselves based on location, agricultural practice, language and religion. The Lao Loum occupy the Mekong River valleys and cultivate wet rice crops, they are predominantly Theravada Buddhist but have strong syncretism with traditional animist beliefs. Lao Theung are culturally distinct from both the Lao Loum and Lao Sung. The Lao Theung generally include Mon-Khmer peoples which are among the indigenous peoples from the Mekong River valleys. The largest single group (11% or 500,000 people) is Khmu (Khmou, Kmhmu, Khammu, Khamu, Kammu).

The Lao Theung peoples are distinguished by dry rice cultivation, and animist beliefs. The Lao Sung are commonly known as “hill tribe” peoples, and are generally among the most recent mass populations to migrate into Laos having arrived in the nineteenth century from southern China and Vietnam. The Hmong are the largest group, which are generally subdivided by traditional dress including the White, Red, Black and Striped Hmong. The Yao (Mien and Lu Mien) are another large group of Lao Sung, and distinguish themselves through the incorporation of Taoist deities with their animist beliefs. Other groups of Lao Sung include the Akha, Kaw, Lahu, Kaduo, Lisu, Hani, Phana, Si La, and Kado. The Lao Sung were heavily recruited by the United States and its allies during the wars against the communists in the 1960s. As much as 10% of the Lao population and 50% of the Lao Sung population fled the communist takeover of Laos in 1975, and continued
