He Jin

He Jin, courtesy name Suigao, was a Chinese military general and politician of the Eastern Han dynasty, serving as military Grand Marshal and regent. He was an elder half-brother of Empress He, and a maternal uncle of Emperor Shao. In 189, he and his sister shared power as regents when the young Emperor Shao was put on the throne following Emperor Ling's death. During the time, the conflict between He Jin and the influential eunuch faction intensified. After they overheard a conversation between He Jin and the empress dowager, the eunuch faction lured him into a trap in the imperial palace and assassinated him. While He Jin's subordinates, led by Yuan Shao, slaughtered the eunuch faction in revenge, Dong Zhuo took advantage of the power vacuum to enter the imperial capital Luoyang and seize control of the Han central government. Dong Zhuo's seizure of control and the subsequent breakdown of central command that followed brought forth the beginning of massive civil wars that lasted for nearly a century, during which time the Han dynasty came to an end and the Three Kingdoms period began in its place.
