Prince of Chu (Ming dynasty)
The Prince of Chu (Chinese: 楚王) was a princely peerage of the Chinese Ming dynasty. It was created in 1370 for Zhu Zhen, the Hongwu Emperor's sixth son by Consort Chong of the Hu clan. Initially the peerage was named the Prince of Qi (Chinese: 齊王), but the name was changed to Chu after the pre-Qin state that used to encompass Wuchang, which was conquered at the time of Zhu Zhen's birth.
