Han Xiandi
In 189, Dong deposed Emperor Shao and replaced him with the Emperor Xian of Han. Dong declared himself chancellor, and became the head of the imperial court in Luoyang. However, in the words of Rafe de Crespigny, Dong Zhuo's "conduct towards the court and the imperial officials was bullying, oppressive and frequently bloody." This prompted Yuan Shao to form an army in opposition to Dong Zhuo's military authority.
