Nguyễn Nhạc
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. He was aided by his brothers Nguyễn Huệ and Nguyễn Lữ. In the early days of the rebellion, Huệ was the most helpful of Nhạc's generals both in finance and in training the army; with the encouragement of Trương Văn Hiến and his own talent, Huệ rapidly increased his own popularity and that of the Tây Sơn Rebellion.
