The Hmong-Mien people, known in Thai as ชาวม้ง-เมี่ยน, have a long history closely tied to Southeast Asia and southern China. Historically, their origins trace back to the Yangtze River valley in China, where they lived in fertile lowland areas. Over centuries, due to conflicts and pressure from the expansion of Han Chinese civilization, they were gradually displaced and migrated southward into more remote, mountainous regions.

In Thailand, the Hmong (ม้ง) and Mien (เย้า) are prominent ethnic groups, primarily residing in the northern highlands. They migrated into Thailand around the late 19th and early 20th centuries from Laos and southern China, seeking refuge from political unrest and war. Traditionally, they practice slash-and-burn agriculture, grow crops like rice and corn, and are known for their vibrant textiles and cultural ceremonies.

Today, the Hmong-Mien people in Thailand maintain their unique identity while integrating into Thai society, contributing to the country’s cultural diversity.
