Emperor Ai of Tang
In 904, Zhu forced Emperor Zhaozong to move the capital from Chang'an to Luoyang, which was even more firmly under his control. Later that year, fearing that the adult Emperor Zhaozong would try to rise against him while he was away on campaigns against other warlords, he had Emperor Zhaozong assassinated. Bypassing Li Yu and the other older princes, he had an edict issued in Emperor Zhaozong's name creating Li Zuo crown prince and changing his name to Li Chu. Shortly after, Li Chu took the throne (as Emperor Ai). Empress He, who survived the assassination, was honored empress dowager.
History of the Ming dynasty
Scattered Ming remnants still existed after 1644, including those of Koxinga (Zheng Chenggong) who established the Kingdom of Tungning on Taiwan (Formosa). Despite the loss of Beijing and the death of the Chongzhen Emperor, Ming power was by no means totally destroyed. Nanjing, Fujian, Guangdong, Shanxi, and Yunnan were all strongholds of Ming resistance. However, there were several pretenders for the Ming throne, and their forces were divided. Each bastion of resistance was individually defeated by the Qing until 1662, when the last southern Ming emperor died, the Yongli Emperor, Zhu Youlang. The last Ming princes to hold out were the Prince of Ningjing Zhu Shugui and Prince Zhu Honghuan (朱弘桓), son of Zhu Yihai, who stayed with Koxinga's Ming loyalists in the Kingdom of Tungning until 1683. Koxinga's grandson Zheng Keshuang surrendered to the Qing dynasty in 1683 and was rewarded by the Kangxi Emperor with the title "Duke of Haicheng" (海澄公) and he and his soldiers were inducted into the Eight Banners,
