Quick Answer
Liu Cong was a Han Zhao ruler and son of Liu Yuan. During his reign, Han Zhao forces captured Luoyang in 311 and took the Jin emperor prisoner.
That event, known as the Yongjia Disaster, destroyed Western Jin's central authority and pushed many northern elites south.
Early Life
Liu Cong came from the same Southern Xiongnu Liu ruling family that founded Han Zhao. He grew up within a regime that used the Han name while fighting Western Jin.
Before ruling, he took part in the anti-Jin military world that was already pressing toward Luoyang.
Rise to Power
After Liu Yuan died in 310, succession quickly turned violent. Liu Cong seized power after killing Liu He, who had briefly succeeded.
Once on the throne, Liu Cong continued the campaign against Western Jin. In 311, Han Zhao forces captured Luoyang and Emperor Huai of Jin.

Major Achievements
1. Capturing Luoyang
The fall of Luoyang was one of the decisive shocks in early medieval Chinese history.
2. Breaking Western Jin authority
Capturing Emperor Huai made Western Jin's claim to order almost impossible to restore in the north.
3. Driving southern migration
The crisis helped push northern aristocrats and refugees south, forming the human background for Eastern Jin.
Why Is Liu Cong Important?
Liu Cong matters because he made Western Jin's collapse visible and irreversible. Liu Yuan had founded the anti-Jin regime, but Liu Cong's reign brought the fall of Luoyang.
His story also connects northern destruction with southern survival. The same crisis that broke Luoyang helped create the Eastern Jin court in Jiangnan.

Mistakes and Controversies
Traditional histories treat Liu Cong very negatively because his reign is tied to the humiliation and collapse of Jin. That judgment is understandable from the Jin-centered perspective.
Yet Han Zhao also had its own succession problems. Liu Cong could destroy Jin's center, but he could not create a stable long-term northern order.
Sources and Historical Tradition
Liu Cong is recorded in the Book of Jin, the Book of Wei, and the Zizhi Tongjian.
These sources describe him mainly through Western Jin's downfall, so readers should separate factual sequence from later moral framing.
Death and Legacy
Liu Cong died in 318. Han Zhao soon faced further internal disorder.
His legacy remains tied to the Yongjia Disaster: the moment Luoyang fell, the Jin emperor was captured, and north China entered a deeper age of fragmentation.
