Duke Huan of Tian Qi

Duke Huan of Tian Qi was from 374 to 357 BC ruler of the State of Qi, a major power during the Warring States period of ancient China. Duke Huans personal name was Tian Wu , and ancestral name Gui . His official posthumous title was simply Duke Huan of Qi, but he is commonly called Duke Huan of Tian Qi to be distinguished from the original Duke Huan of Qi from the House of Jiang, who was the first of the Five Hegemons of the Spring and Autumn Period.

Duke Huan was born in 400 BC, during the reign of Duke Kang, the last Qi ruler from the House of Jiang. In 386 BC Duke Kang was deposed by Duke Huans father Duke Tai of Tian Qi, the first Qi ruler from the House of Tian. Duke Tai died in 384 BC and was succeeded by his son Tian Yan, Duke Huans elder brother. In 375 BC Duke Huan murdered Tian Yan and his son Tian Xi, and usurped the throne.
