The Thadou are a Kuki people located chiefly in the hill country adjacent to the Imphal Valley in the northeastern Indian state of Manipur. This area encompasses some 26,000 square kilometers. The Thadou share many cultural affinities with the Koms, Aimols, Khotlhangs, Lusheis, Chins, Pois, Suktes, Paites, and Gangtes.
In 1983 there were 125,100 Thadou living in India and 26,200 living in Myanmar (Burma). The Thadou language belongs to the Tibeto-Burman Family of the Sino-Tibetan Phylum. It shares many elements with Metei, Kachin, Garo, Lushei, and other Old Kuki dialects.
