晋献公
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.
