Duke Huan of Qi

Duke Huan of Qi (), personal name Lü Xiaobai, was a duke of the Qi state, ruling from 685 BC to 643 BC.

Duke Huan and his long-time advisor Guan Zhong managed to transform Qi into China's most powerful polity. Duke Huan is commonly listed among the Five Hegemons of the Spring and Autumn period. Toward the end of his more than 40-year-long reign, however, Duke Huan's power began to decline as he grew ill and the Qi state came to be embroiled in factional strife. Following his death in 643 BC, Qi completely lost its predominance. Provided by Wikipedia
