Tai Federation

1948 CE – 1954 CE · capital Lai Chau

A French-backed autonomous federation of Tai peoples in north-western Vietnam, led by Deo Van Long and ended by the fall of Dien Bien Phu.

Origins

The Sip Song Chau Tai, 'twelve Tai lands', of the Black River region had long been ruled by Tai chiefly families such as the Deo of Lai Chau. In 1948 France formally created the Tai Federation under Deo Van Long, who had backed the French against the Viet Minh, as part of its strategy of ethnic autonomous zones.

Rule and society

The federation was governed from Lai Chau by Deo Van Long with Tai, Hmong and other upland chiefs, under French military protection, and fielded Tai battalions alongside French units. It was nominally attached to Bao Dai's State of Vietnam from 1950. Opium was an important part of the local economy and of French financing in the region.

Decline and legacy

Viet Minh offensives overran much of the area in 1952 to 1953, and Lai Chau was evacuated before the battle of Dien Bien Phu in 1954. The Geneva Accords gave the region to North Vietnam, which created the Thai-Meo Autonomous Region, later renamed Tay Bac; Deo Van Long went into exile in France.
