Nguyễn Nhạc
In the late 18th century, a rebellion broke out in southern Vietnam. The Nguyễn lords, the hereditary rulers in southern Vietnam, were overthrown by the Tây Sơn brothers: Nguyễn Nhạc, Nguyễn Huệ and Nguyễn Lữ in 1777. With the help of supporters, Nguyễn Ánh, a nephew of the last Nguyễn lord, reconquered Gia Định (present day Hồ Chí Minh City) as "Đại nguyên súy Nhiếp quốc chính" ("Commander in chief and regent") and later proclaimed himself "Nguyễn Vương" ("Nguyễn king").
