Zhu Youjian was a Ming emperor. His era name was Chongzhen. The simplified Chinese Wikidata alias is Zhu Youjian, and the English alias is the same spelling, so the title uses that personal name.[1] This entry records his birth on 6 February 1611 and his death on 25 April 1644, and describes him as the last emperor of the Ming.[1]
The cited history
The Ming History juan attached to this entry is juan 11. Its heading is the annals of the Jing Emperor. The opening gives that emperor's personal name as Qiyu, the second son of the Xuande Emperor. The passage read there does not mention the Chongzhen era or Zhu Youjian. Those events are not transferred to this entry.[3]
