Чжу Юаньчжан
In 1373 the Hongwu Emperor shifted his focus back to Nanjing, with a substantial program of expansion and refurbishment of the palace which was completed in 1375. Further expansion occurred in 1392. In 1398 the Hongwu Emperor died, and was succeeded by his grandson, the Jianwen Emperor. A civil war soon ensued as Zhu Di, son of the Hongwu Emperor and uncle of the Jianwen Emperor, sought to take the crown from his nephew.
