Duke Wu of Lu

Duke Wu of Lu, personal name Ji Ao, was a duke of the Lu state. He succeeded his brother, Duke Shen.

In spring of the ninth year of his reign, he paid a visit to King Xuan of Zhou with his heir apparent Kuo and younger son, Xi. King Xuan appreciated Xi greatly, and despite the objections of his councillor Zhongshan Fu (仲山甫), he decided to intervene and appoint Xi as the heir apparent over his elder brother. In summer, the three returned to Lu, and Duke Wu died shortly after.
