Emperor Ling of Han was the 13th emperor of the Han Dynasty in China, ruling from 168 to 189 AD. He was born Liu Hong and became emperor at a young age after the death of his father, Emperor Huan. His reign is often marked by political instability and corruption within the court. During Emperor Ling's rule, the power of the eunuchs grew significantly, leading to conflicts with the noble families and other officials. His reign ended with his death, which triggered a power struggle that contributed to the eventual decline of the Han Dynasty.
