general whose seizure of power and tyrannical rule ended the Han dynasty (206 BCE–220 CE) and divided the Chinese empire.

In 190 CE Dong Zhuo burned Luoyang, the capital, and removed himself and the emperor to the ancient capital of Chang'an (now Xi'an). At his fief he built the walled fortress (Meiwu), said to have been an exact duplicate of the wall of the capital. Opposition to his rule sprang up throughout the country, and the empire gradually became divided into satrapies ruled by rival generals. Dong was assassinated by one of his own lieutenants, who was also his adopted son, at the bidding of a rival.
