Cui Hao

Cui Hao () (died 5 July 450), courtesy name Boyuan (伯淵), was a ''shangshu'' of the Xianbei-led Northern Wei dynasty of China. Largely because of Cui's counsel, Emperor Taiwu of Northern Wei was able to unify northern China, ending the Sixteen Kingdoms era and, along with the Liu Song dynasty in southern China, entering the Northern and Southern dynasties era. Also because of the influence of Cui, who was a devout Taoist, Emperor Taiwu became a devout Taoist as well. However, in 450, over reasons that are not completely clear to this day, Emperor Taiwu had Cui and his cadet branch executed. Provided by Wikipedia
