Cao Pi was the first emperor of the state of Cao Wei. He ruled during the Three Kingdoms period in China. This era followed the collapse of the Eastern Han dynasty. Cao Pi was the second son of the warlord Cao Cao. However, he was the eldest son born to Lady Bian.

He grew up training in martial arts. He studied swordsmanship from Shi E. Shi E was part of the "Rapid as Tigers" division. This was a corps of soldiers serving as imperial bodyguards. These guards were likely candidates for future military appointments.

Succession within the Cao family was a complex struggle. Although Cao Pi was the presumptive heir, doubts existed for many years. His brother, Cao Zhi, was a very famous poet and speaker. Cao Zhi had many supporters who rivaled Cao Pi's own group. In 216, Cao Zhi's party successfully accused two of Cao Pi's officials. This led to the execution of Cui Yan and the removal of Mao Jie. Eventually, the strategist Jia Xu advised Cao Cao to follow primogeniture. This is the rule where the eldest son inherits the position. In 217, Cao Cao officially named Cao Pi as his heir apparent.

When Cao Cao died in the spring of 220, instability followed. A military unit called the Qingzhou Corps suddenly deserted Luoyang. There were also rumors that Cao Pi's brother, Cao Zhang, wanted power. Cao Pi acted quickly to secure his position. He declared himself the King of Wei using his mother's authority. He then received official confirmation from Emperor Xian. In the winter of 220, Cao Pi moved to take the imperial throne. He asked Emperor Xian to abdicate, which means to step down. Following a traditional model, Cao Pi declined the throne three times before accepting. On November 25, 220, he established the state of Cao Wei. This transition ended the Han dynasty and began the Three Kingdoms period.

Cao Pi's reign was defined by constant military pressure. He faced two major rival states: Shu Han and Eastern Wu. Liu Bei founded Shu Han in 221 after hearing news of Cao Pi's rise. Sun Quan controlled the south and initially offered to be a vassal to Wei. A strategist named Liu Ye suggested attacking Sun Quan to split his territory. Cao Pi declined this advice and instead granted Sun Quan the title of King of Wu. This choice is seen by many historians as a missed opportunity. Later, Sun Quan refused to send his heir as a hostage. This led to a formal break in ties and the establishment of Eastern Wu. Cao Pi led expeditions against them but could not make significant gains. He famously remarked that the Yangtze River divided the north from the south.

Internal administration was a primary focus for Cao Pi. Unlike his father, he concentrated more on governing than on constant warfare. He formally established the nine-rank system created by Chen Qun. This system was used for civil service nomination. It helped the government recruit many talented individuals based on ability. However, Cao Pi was not always open to criticism from his staff. Officials who disagreed with him often faced demotion or death. He was known to ridicule his subordinates in various situations. One example involved the general Yu Jin, whom Cao Pi treated with bluntness.

To protect his own authority, Cao Pi changed how princes were treated. He was still resentful of his brother Cao Zhi's talents. Consequently, he reduced the size of Cao Zhi's fief, or land holding. He also executed several of Cao Zhi's associates. Under Cao Pi's new regulations, Wei princes had very little power. They were kept away from central politics and restricted in military use. This prevented them from opposing the emperor, but it also meant they could not help during a crisis. This was a major shift from how princes were treated during the Han dynasty.

Beyond politics, Cao Pi was a highly accomplished scholar. He followed the literary traditions of his father and brother. He was a talented poet who contributed to Chinese literature. He wrote the first Chinese poem using a seven-syllable line style. This style is known as seven-syllable verse. In addition to poetry, he wrote over one hundred articles on many subjects. After his death, his successor Cao Rui gave him the posthumous name Emperor Wen. He was also given the temple name Gaozu to honor his role as a founder.
