Hongwu Emperor

Zhu Yuanzhang lost everything to the epidemics and famines that tore through 14th-century China under Mongol rule, spending time as a novice monk begging for alms and watching how ordinary people suffered. In 1352 he joined the Red Turban rebels, and within four years commanded his own army and held Nanjing. He beat rival warlords - decisively at Lake Poyang in 1363 - then declared himself King of Wu while still formally recognizing the Red Turban's figurehead. In early 1368 he renamed his state Da Ming, "Great Radiance", took the reign name Hongwu, "Vastly Martial", and spent the next four years driving the Yuan armies north and unifying China. His thirty-year reign rebuilt a country hollowed out by war: he distrusted book-learned scholars, built institutions through pragmatic reform rather than Confucian moral example, and kept his army disciplined enough to spare civilians. Mongolia itself stayed out of reach.
