Biography
Zhu Yihai was born in 1618, during the 46th year of the reign of the Wanli Emperor of the Ming Dynasty. A son of Zhu Shouyong, he was a ninth-generation descendant (the same generation as the Taichang Emperor) of Zhu Tan, Prince Huang of Lu, tenth son of Hongwu Emperor.
The mansion of the Prince of Lu was located at Yanzhou. The Qing forces had attacked Yanzhou and destroyed the mansion. At that time, the peerage of Prince of Lu was succeeded by Zhu Yihai's eldest brother, Zhu Yipai. After the Qing invaded, Zhu Yipai committed suicide along with two of his brothers, Zhu Yixing (朱以洐) and Zhu Yijiang (朱以江).
After his brother's suicide, Zhu Yihai was enfeoffed as the 11th Prince of Lu by Chongzhen Emperor. After four days he succeeded his peerage, Li Zicheng attacked Beijing and he fled to southern China.
Reign
The Prince of Lu was part of the resistance against the invading Qing dynasty forces. His primary consort, Lady Chen, committed suicide during the impending fall of the Ming. The location of her suicide can still be found on the island of Zhoushan.
In 1651 he fled to the island of Kinmen, which in 1663 was taken over by the invading force. His grave was discovered on the island in 1959, which disproved the theory advanced by the 18th-century History of Ming that he was killed by Koxinga. His eldest son, Zhu Honghuan (朱弘桓), married the fourth daughter of Koxinga and went to live in the Kingdom of Tungning Taiwan under the protection of Zheng Jing, his brother-in-law and worked as a farmer. Another Ming prince who accompanied Koxinga to Taiwan was Zhu Shugui, Prince of Ningjing.
After the surrender of the Kingdom of Tungning, the Qing sent the 17 Ming princes still living on Taiwan back to mainland China where they spent the rest of their lives. Including Zhu Honghuan.
