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 , 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.
