Zhuo Dong

Dong Zhuo (138 - May 22, 192) was a powerful warlord during the late Eastern Han Dynasty and Three Kingdoms era of China. He seized control of Luoyang in 189 after the capital fell into chaos following the death of Emperor Ling and a bloody clash between the powerful eunuch faction and the court officials. Dong Zhuo subsequently deposed the rightful heir to the throne and instated the puppet Emperor Xian. However, Dong Zhuo's tyrannical and cruel ways angered many, and warlords around the country formed a coalition against him, forcing him to move the capital west to Chang'an.

Dong Zhuo was eventually assassinated by his adoptive son Lü Bu as part of a plot by Interior Minister, Wang Yun. (Source: Wikipedia)
