Cao Pi (187 – 29 June 226), courtesy name Zihuan, was the first emperor of the state of Cao Wei in the Three Kingdoms period. He was born in Qiao (譙; present-day Bozhou, Anhui) as the second son of Cao Cao, a warlord who lived in the late Eastern Han Dynasty. However, he was the eldest son among all the children born to Cao Cao by his concubine (later wife) Lady Bian. Of all his brothers, Cao Pi was the most shrewd. Instead of focusing on academic studies or administering military affairs, he was always in the presence of court officials in order to gain their support. He was mostly in charge of defence[clarification needed] at the start of his career. After the defeat of Cao Cao's rival Yuan Shao at the Battle of Guandu, he took the widow of Yuan Shao's son Yuan Xi, Lady Zhen, as a concubine, although eventually she lost his favour and was forced to commit suicide. After he became emperor, his other favourite, Guo Nüwang, became empress.
