Wei State (65438+February 1 1, 220-February 8, 266) was one of the separatist regimes in the Three Kingdoms period, and later historians often called it Cao Wei. Since the Northern Wei Dynasty was later called the "post-Wei" and Cao Wei was also called the "pre-Wei" or "pre-Wei", it became the most powerful country among the three countries.

At the end of the Eastern Han Dynasty, there was chaos and competition. In the melee of warlords, Cao Cao's power gradually increased, and he controlled the court of the Eastern Han Dynasty, which laid the foundation for the establishment of Cao Wei. When Cao Cao was awarded the title, he ruled Ye, the seat of Wei Jun in the Eastern Han Dynasty. So Emperor Xian of the Han Dynasty named him "Gong Wei" and "Wang Wei", and his son Cao Pi established the title of "Wei".

In the first year of Yankang (220), Cao Pi forced Emperor Xiandi of Han Dynasty to abdicate, formally replacing the Han Dynasty, establishing Cao Wei, and making Luoyang its capital. In the second year of Xian Di (265), Bingyin usurped Wei, changed his title to Jin, and Cao Wei perished.

The territory of Cao Wei

The territory of Cao Wei developed greatly mainly in the Cao Cao period, and was shaped after Cao Pi proclaimed himself emperor and founded the country, occupying about the whole of North China. Roughly north to Shanxi, Hebei and Liaodong, and south to Xiongnu, Xianbei and Koguryo; East to the Yellow Sea. Southeast and Sun Wu across the river, Huaihe River, Han River confrontation, Shouchun, Xiangyang for the town. West to Gansu, adjacent to Xianbei, Qiang and Bian in Hexi.

Southwest China confronts Shu and Han in Qinling and Hexi areas, and Chang 'an is an important town. After the founding of the People's Republic of China, there were 87 counties 12 states, including: Li Si, Xuzhou, Qingzhou, Yuzhou, Jizhou, Bingzhou, Youzhou, Yanzhou, Liangzhou, Yongzhou, Jingzhou (the Eastern Han Dynasty occupied the northern part of Jingzhou) and Yangzhou (the Eastern Han Dynasty occupied the northern part of Yangzhou).

Cao Wei established a long history of the western regions in charge of Haitou (now Lop Nur, Xinjiang) and a captain of Wuji in charge of Gaochang in the western regions. In the second year of Huang Chu (22 1), after Sun Quan became a vassal, Cao Wei made Sun Quan own Jingzhou Pastoral, and made Jingyang and other Sun Quan forces Jingzhou, and the northern part of Jingzhou directly under Cao Wei was renamed Yunzhou. After the two sides broke up, Cao Wei changed Yunzhou to Jingzhou. From the first year of Huang Chu (220) to the seventh year of Huang Chu (226), Longyou was included in Qin Zhou and finally merged into Yongzhou. After Shu Han was destroyed, Yizhou was divided into Liangzhou, and * * * added two states.
