Cao Lin

Cao Lin (died 5 February 251) He was enfeoffed as the Prince of Hedong (河東王) on 8 April 222 during his father's reign. In 225, his title was changed to "Prince of Guantao" (館陶王).

In 227, after Cao Pi's death, Cao Lin's half-brother Cao Rui succeeded their father and became the second emperor of Wei. Cao Rui treated Cao Lin in an exceptionally generous manner in accordance with their father's final wishes. Cao Lin was known for being prone to domestic violence; he abused and killed servants and concubines alike. In 232, his title was changed again to "Prince of Donghai" (東海王). He died on 5 February 251 during the reign of Cao Fang, the third emperor of Wei. He was honoured with the posthumous title "Prince Ding" (定王).

Cao Lin had two sons: Cao Qi (曹啟) and Cao Mao (曹髦). The elder one, Cao Qi, inherited his princedom and became the next Prince of Donghai. Over the reigns of the subsequent Wei emperors, the number of taxable households in the Donghai princedom increased until it reached 6,200. Cao Lin's younger son, Cao Mao, initially held the title "Duke of Gaogui District" (高貴鄉公). In 254, following Cao Fang's death, Empress Dowager Guo selected Cao Mao to be the fourth emperor of Wei. In accordance with imperial customs, Cao Mao was adopted as a posthumous son of Cao Rui so that his succession would be considered legitimate.
