Duke Xian of Jin

Duke Xian of Jin (, died 651 BC), ancestral name Ji (姬), given name Guizhu (詭諸), was the nineteenth ruler of the State of Jin. He was also the ninth ruler of Jin in the Spring and Autumn period and the second duke of Jin. When his father, Duke Wu of Jin, died in 677 BC, Guizhu ascended the throne of Jin and became Duke Xian of Jin. He reigned for 26 years. He moved the capital from Quwo (曲沃) to Jiang (絳). He was named after a Rongdi tribe (戎狄族) leader Guizhu (詭諸) whom his father, Duke Wu of Jin, captured alive. During his reign, the State of Jin was one of the most powerful and largest states due to his conquests in many small neighboring states. He is also renowned for the slaughter and exile of many royal family members of Jin and for favoring one of his concubines named Li Ji. Rise to power When he ascended the throne, Duke Xian of Jin and the duke of Guo visited King Hui of Zhou and they were given rewards which resulted to the increase of their popularity throughout the states. He also adopted a strategy that his official, Shi Wei (士蒍), suggested which involves the slaughter and exile of almost all the royal family members of Jin to ensure that the throne of Jin will always be held by one of his descendants. This resulted to the increase of the power of the duke and the loss of political power of the clan of the duke since the clan was almost annihilated. To increase the military power of the state, he expanded his army into 2 troops, each having 10,000 men (some say 12,500). In 672 BC, the fifth year of his reign, he eliminated the Li Rong tribe and he obtained two women from the tribe: Li Ji and her younger sister, Shao Ji (少姬). Both women were favored by Duke Xian of Jin.
