Prince of Chu (Ming dynasty)

Prince of Chu peerage (楚王) was created in 1370 for Zhu Zhen, Hongwu Emperor's sixth son by Consort Chong of the Hu clan. Initially the peerage was named as Prince of Qi, however the name was changed to Chu after the ancient Chinese kingdom that used to encompass Wuchang, which was conquered at the time of Zhu Zhen's birth.
