Marquis Wu of Wei (魏武侯, Ngụy Vũ hầu; personal name Wei Ji 魏击; reigned 395–370 BC), was the second monarch of the State of Wei during the Warring States period, son of the founding reformer Marquis Wen of Wei (Marquis Wen of Wei).
Inheriting a flourishing superpower, Marquis Wu aggressively expanded Wei’s territory, commanding the elite Wei Wuzu infantry in campaigns against Qi, Qin, and Chu. While sailing down the West River, he famously boasted to general Wu Qi: ‘Look upon the grandeur of these mountains and rivers; is this not the supreme treasure of Wei?!’ Wu Qi famously retorted: ‘A state’s safety lies in virtue, not in strategic crags (在德不在险).’ Tragically, Marquis Wu later listened to slanders from chancellor Gongshu Cuo, driving Wu Qi to flee to Chu. Marquis Wu died in 370 BC without naming an heir, triggering a fierce succession war between his sons.
