Five Hegemons
Wuzhi usurped the Qi throne after murdering Duke Xiang, but was killed by minister Yong Lin (雍廩) just a few months later in spring 685 BC. After a brief struggle between Duke Xiang's two younger brothers Prince Jiu and Prince Xiaobai, Xiaobai would prevail and ascend the throne, posthumously known as Duke Huan of Qi. Qi would grow strong under Duke Huan's rule, and Duke Huan subsequently became the first of the Five Hegemons of the Spring and Autumn period.
