Sip Song Chau Tai

Sip Song Chau Tai ('twelve Tai lands') was the traditional name for the Tai principalities of the Black River region of north-western Vietnam. Each was ruled by hereditary Tai chiefly families, such as the Deo of Lai Chau, which at various times paid tribute to Vietnamese, Lao or Chinese courts. Under French rule the region became the basis of the Tai Federation of 1948–1954.
