Emperor Liu Hong, also known as Emperor Huan of Han, was the 10th emperor of the Han Dynasty in China. He reigned from 146 to 168 AD and was the son of Emperor Ling. His rule was marked by political instability and the increasing power of court eunuchs, which led to corruption and factional struggles within the imperial court. During his reign, Emperor Liu Hong faced challenges from various factions, including the Daoist sects and the noble families. His inability to effectively manage these conflicts contributed to the decline of the Han Dynasty. He died at a young age, and his death led to further turmoil in the empire.
