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. In 665 BC, the twelfth year of his reign, Li Ji gave birth to
Xiqi. Since Duke Xian of Jin favored Li Ji, he had a desire to dethrone
Shensheng, the eldest son of Duke Xian of Jin, from his position as crown prince to make Prince Xiqi the crown prince instead, so he sent Prince Shensheng to defend Quwo, modern
Quwo County in
Shanxi. Duke Xian of Jin also sent
Prince Chong'er to defend the city of
Pu and
Prince Yiwu to Erqu (二屈), modern
Ji County in Shanxi. In 661 BC, the sixteenth year of his reign, he conquered the state of Geng (耿), the state of Huo (霍), the old state of Wei (魏) and the Rongdi tribe. The Jin official
Bi Wan (畢萬) was given the land of the old state of Wei, and his descendants will later establish the new state of
Wei. The Jin official
Zhao Su (趙夙) helped conquer the state of Huo so he was given the land of the state of Geng and his descendants will later establish the state of
Zhao. (Altogether Duke Xian annexed 17 states and subjugated 38 others.) ==Li Ji Rebellion==
