Liu Qing

Liu Qing (; 78 – 1 February 107), formally Prince Xiao of Qinghe (清河孝王) or Emperor Xiaode (孝德皇), was a crown prince of the Han dynasty under his father Emperor Zhang who lost his position and his mother Consort Song due to palace intrigue at the hands of his father's wife Empress Dou. He, however, maintained a strong relationship with his half-brother Emperor He, and was able to avenge himself and his mother in conjunction with his brother. During his lifetime, he saw his son Liu Hu (劉祜) become emperor (as Emperor An) as successor to his nephew Emperor Shang, who died in infancy.
