From the Yongle Emperor onwards, 13 Ming dynasty emperors were buried in the same area. The Xiaoling tomb of the first Ming emperor, the Hongwu Emperor, is located near his capital Nanjing; the second emperor, the Jianwen Emperor, was overthrown by the Yongle Emperor and disappeared, without a known tomb. The "temporary" emperor, the Jingtai Emperor, was also not buried here, as the Tianshun Emperor had denied him an imperial burial; instead, the Jingtai Emperor was buried west of Beijing. The last emperor buried at the location was Chongzhen, the last of his dynasty, who committed suicide by hanging on April 25, 1644. He was buried in his concubine Consort Tian's tomb, which was later declared as an imperial mausoleum "Si Ling" by the emperor of the short-lived Shun dynasty, Li Zicheng, with a much smaller scale compared to the other imperial mausoleums built for Ming emperors.
