Cao Fan (simplified: 曹范, traditional: 曹範, pinyin: Cáo Fàn) was the third son of Cao Ren, one of Cao Wei’s most distinguished generals and a cousin of Cao Cao. Like his elder brothers, he was enfeoffed as a marquis under Cao Wei. After his eldest brother Cao Tai died, Cao Fan inherited the main family title and marquisate.
Biography
Family background
Cao Fan was born into one of the most powerful families in Cao Wei. His father, Cao Ren, was a cousin of Cao Cao and one of the most trusted and capable military commanders of the Wei state. Cao Ren served as General-in-Chief (大將軍) and was enfeoffed as Marquis of Chen (陳侯). He died in 223 and was posthumously honoured as Marquis Zhong (忠侯), meaning “Loyal Marquis.”
Cao Ren had at least three sons:
- Cao Tai (曹泰), the eldest son, who inherited his father’s marquisate and served as General Who Garrisons the East (鎮東將軍). He held the office of Prefect of the Masters of Writing (尚書) and was later appointed General of Agile Cavalry (驃騎將軍) with authority to oversee military affairs in the regions of Jing and Yu. Cao Tai was enfeoffed as Marquis of Ningling (寧陵侯).
- Cao Kai (曹楷), the second son, who was enfeoffed as a marquis.
- Cao Fan (曹範), the third son, also enfeoffed as a marquis.
Inheritance
When Cao Tai died, his own son Cao Chu (曹初) was young. According to some accounts, the main family marquisate passed not to Cao Chu but to Cao Fan, the third son of Cao Ren, who inherited the title. The precise details of this succession are not fully preserved in the surviving records.
Career
Beyond the fact that he was enfeoffed as a marquis and inherited the family title, the surviving sources provide no detail on Cao Fan’s career, offices, or personal achievements. He appears in the Records of the Three Kingdoms only as part of the genealogical notes appended to his father’s biography.
Historical sources
Cao Fan is mentioned briefly in the Records of the Three Kingdoms (SGZ), in the biography of his father Cao Ren (volume 9, Book of Wei). The entry records only his status as Cao Ren’s son and his enfeoffment as a marquis. No independent biography exists for him.
Family
Cao Fan was the third son of Cao Ren. His elder brothers were Cao Tai, who inherited their father’s marquisate and military commands, and Cao Kai, who was also enfeoffed. The identity of Cao Fan’s mother is not recorded in the surviving sources.
