History
editAt the end of the sixteenth century Yên Bái was a small village in Bach Lam district, Quy Hoa district, Hung Hoa province. On April 11, 1900, Yen Bai province was established by the French colonialist government. The city grew in size with the opening of the Hanoi–Lào Cai railway, which attracted many migrants.
On February 10, 1930, part of the 4th Regiment of Tonkinese Rifles stationed at Yen Bai mutinied against their French officers in the Yên Bái mutiny. They were suppressed by loyal troops from the same unit. This incident led to widespread disturbances against French rule across northeastern Vietnam during 1930–31.[3]
