Zhu Jianxun

Zhu Jianjun (1456–1527) was a Chinese noble figure during the Ming Dynasty, recognized as the seventh son of Emperor Yingzong of Ming. His mother was Consort Wan, one of Emperor Yingzong's concubines. Zhu Jianjun held the title of Prince of Ji (吉王).

Born in 1456, Zhu Jianjun's early years coincided with a period when Emperor Yingzong was under house arrest in the Southern Palace. Following Emperor Yingzong’s restoration to the throne in 1457, Zhu Jianjun was granted the title of Prince of Ji. On October 25, 1477, he was assigned to his territorial domain in Changsha Prefecture.

Throughout his life, Zhu Jianjun was known for his moral principles. He engaged in scholarly pursuits and valued acts of virtue. He visited the Yuelu Academy to study ancient sages and created a portrait of one of them. He also possessed a copy of the Book of Documents, which he frequently consulted. His leisure activities included writing and reading classical texts, notably Jia Dafu Xinshu, which likely refers to Jia Yi's Jiazi Xinshu.

Zhu Jianjun governed his princedom for approximately fifty years until his death in 1527. Posthumously, he was given the name "Jian" (簡). His designated heir, Zhu Youfu, died prematurely and was posthumously named "Dao" (悼). Subsequently, Zhu Jianjun’s grandson, Zhu Houfu, succeeded him as the Prince of Ji in 1529.

His familial relationships include a daughter, Princess Shanhua (善化郡主), who was married to Shi Ce (史策).

In later generations, descendants of Zhu Jianjun included Zhu Jianfan (1883–1932), a revolutionary educator in China and a close associate of Mao Zedong. Zhu Jianfan was also the father-in-law of notable figures Xiao Jingguang and Wang Jiaxiang.

References to Zhu Jianjun are primarily recorded in historical texts regarding Ming Dynasty nobility, and he is noted for his moral conduct, scholarly interests, and familial legacy.
