Wei (state)
Wei was one of the seven major states during the Warring States period of ancient China. It was created from the three-way Partition of Jin, together with Han and Zhao. Its territory lay between the states of Qin and Qi and included parts of modern-day Henan, Hebei, Shanxi, and Shandong. After its capital was moved from Anyi to Daliang during the reign of King Hui, Wei was also called Liang.
It should not to be confused with the smaller central Wey state 衞, which is still sometimes only differentiated by its Chinese character.
History
Foundation
Surviving sources trace the ruling house of Wei to the Zhou royalty: Gao, Duke of Bi, was a son of King Wen of Zhou. His descendants took their surname, Bi, from his fief. Bi Wan served the Jin, where he became a courtier of Duke Xian's. After a successful military expedition, Bi Wan was granted the fief of Wei, from which his own descendants then founded the house of Wei.Spring and Autumn period
Jin's political structure was drastically changed after the slaughter of its ruling dynasty during and after the Li Ji Unrest. Afterwards, "Jin ha no princely house" and its political power diffused into extended relations of the ruling family, including the Wei. They became largely independent by the middle of the fifth century.In the last years of the Spring and Autumn period, the founders of Wei, Zhao, and Han joined to attack and kill the dominant house of Zhi in 453 BCE, resulting in the partition of Jin. Following the partition, the three positioned themselves as heirs to Jin's grandeur, acting as hegemonic powers. King Weilie of Zhou finally legitimized the situation in 403 BCE, when he elevated the three houses' heads to the rank of marquess.
Warring States Period
The state of Wei approached its apogee in the 360's BCE, following the reigns of its first two rulers, Marquess Wen of Wei and Marquess Wu of Wei. The third ruler, King Hui of Wei, declared himself an independent sovereign and concentrated on economic developments, including irrigation projects at the Yellow River and adoption of Legalist reforms proposed by Li Kui.Hui felt that Qin in the west was weak and their land a barren waste. He focused on conquering the well-settled eastern lands which were richer in known resources, but a series of battles including the battle of Maling in 341 BCE checked Wei's ambitions while Qin's expansion went largely unimpeded, boosting its economy and military strength.
Defeat
Wei eventually lost the western Hexi region, a strategic area of pastoral land on the west bank of the Yellow River between the border of modern-day Shanxi and Shaanxi, to Qin. Thereafter, it remained continuously at war with Qin, requiring the capital to be moved from Anyi to Daliang. Wei surrendered to Qin in 225 BCE, after the Qin general Wang Ben diverted the Yellow River into Daliang, destroying the capital in a flood.Rulers
