The Tay Son Rebellion covers a major civil war in Vietnam. The country had been divided into north and south for 150 years: the Trinh dynasty in the north, and the Nguyen dynasty in the South. Both dynasties allowed corruption to grow, and their people suffered. The three Ho brothers started a peasant uprising in the center, in Tay Son, and eventually defeated both warlords. They let a young Nguyen prince escape, and he is helped by a French Catholic Bishop, who raises a small French Navy in India to help the young Prince Nguyen Anh attack the Ho brothers. The outcome helps determine important parameters of modern Vietnam. More at TheTaySonRebellion.com.
