Hangu Pass
In early 190, Wang Kuang joined a coalition of warlords from the east of Hangu Pass in a campaign against the warlord Dong Zhuo, who seized power in 189 and dominated the Han central government. Wang Kuang led his troops to attack Dong Zhuo from the north but lost to the enemy at the Battle of Heyang Ford. When Dong Zhuo sent Humu Ban (胡母班), who married a younger sister of Wang Kuang, and other officials to negotiate a truce, Wang Kuang had them executed. In 191, Humu Ban's relatives turned against Wang Kuang and had him killed in revenge. After his death, Dong Zhuo appointed Zhang Yang as the new Administrator (太守) of Henei Commandery.
