Seeking to overthrow the corrupted Trương Phúc Loan and to help the prince Nguyễn Phúc Dương, the eldest of the Tây Sơn Brothers, Nguyễn Nhạc, gathered an army and revolted in 1771.
Due to its popularity, the Tây Sơn army grew strong and attracted many talented generals, (such as Nguyễn Thung, Bùi Thị Xuân, Võ Văn Dũng, Võ Đình Tú, Trần Quang Diệu, Trương Mỹ Ngọc, and Võ Xuân Hoài).
