The Taichang Emperor, born Zhu Changluo on August 28, 1582, was the 15th emperor of the Ming dynasty in China. As the eldest son of the Wanli Emperor, he succeeded his father in 1620 but faced a brief reign lasting less than one month. The emperor unexpectedly died in the palace after experiencing a bout of diarrhea. Following his death, his son Zhu Youjiao ascended the throne as the Tianqi Emperor. The Taichang Emperor’s era name, “Taichang,” translates to “grand prosperity,” yet his reign holds the record as the shortest in Ming history, marked by its abrupt and premature conclusion.
