Liu Cong, emperor of the Xiongnu state

Liu Cong (died 31 August 318), courtesy name Xuanming, nickname Zai, also known by his posthumous name as the Emperor Zhaowu of Han (Zhao), was an emperor of the Xiongnu-led Chinese Han-Zhao dynasty. During his reign, the Han-Zhao brought about the fall of the Western Jin dynasty, leading to its re-establishment in the south as the Eastern Jin dynasty at Jiankang in 318. His forces conquered the ancient Chinese capitals of Luoyang and Chang'an. He also captured Emperor Huai of Jin and Emperor Min of Jin, who he both had executed after forcing them to act as cupbearers.
