He was a grandson of Marquess Wen of Wei, the founder of the state, and a son of Marquess Wu of Wei.[citation needed ] He was succeeded by his son, King Xiang of Wei.
He came to the throne after a war of succession during which his state was nearly partitioned by Zhao and Han. For his wars and eventual defeat by Qi and Qin in 340, see Warring States period.[citation needed ]
