In East China, in an attempt to restore the power of the Han, a large coalition against Dong Zhuo began to rise, with leaders such as Yuan Shao, Yuan Shu, and Cao Cao. Many provincial officials were compelled to join or risk elimination. In 191, Sun Jian (Yuan Shu's subordinate) led an army against Dong Zhuo and drove him from Luoyang to Chang'an. In the following year (192), Lü Bu, Dong Zhuo's former bodyguard, assassinated Dong Zhuo. It is said that Dong Zhuo's body was thrown into the street with a lit wick in his naval, which apparently burned with the same brilliance of the sun.
