Liu Xuan (91-48 BC) was one of the best emperors of the Han Dynasty. Months after he was born most of his family were killed and the only safe place for him was the prison where he spent the first few years of his life. When he was around 5 years old he was able to live with a family and had a normal life. However, when he was 17 he was told that he was the closest living family member of the royal family and that he was now the emperor. He moved to the big palace where he started his long reign as emperor.
