Emperor Xian of Han
Dong Zhuo seized control of the imperial capital Luoyang in 189 when it entered a state of turmoil following the death of Emperor Ling of Han and a massacre of the eunuch faction by the court officials led by General-in-Chief He Jin. Dong Zhuo subsequently deposed Liu Bian (Emperor Shao) and replaced him with his half-brother, the puppet Emperor Xian of Han. Dong Zhuo's rule was brief and characterized by cruelty and tyranny. In the following year, a coalition of regional officials (cishi) and warlords launched a campaign against him. Failing to stop the coalition forces, Dong Zhuo sacked Luoyang and relocated further west to the former Western Han capital at Chang'an (modern Xi'an, Shaanxi province). He was assassinated soon after in 192 by his subordinate Lü Bu in a plot orchestrated by Interior Minister Wang Yun.
