晋献公
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.
