Zhu Gaosui (19 January 1383 – 5 October 1431) was a prince of the Ming dynasty.
He was the third son of the Yongle Emperor and an ally of his second brother, Zhu Gaoxu, who was the rival to their eldest brother, Zhu Gaochi, in the power struggle over succession.
[1] Along with his older brother Zhu Gaoxu, he took part in military campaigns during the civil war of 1399–1402,[2] which ultimately led to his father's ascension to the throne as the emperor of the Ming dynasty.
[3] In 1426, he became involved in a rebellion led by his elder brother, Zhu Gaoxu, against their nephew, the Xuande Emperor.
[4] He died in 1431, and his title of Prince of Zhao was inherited by his second son, Zhu Zhanque (朱瞻塙; 1413–1455), as his eldest son, Zhu Zhanba (朱瞻坺; 1411–1427), had died a few years earlier.
