. In 637 BC Chong'er, son of Duke Xian of Jin got into difficulties when passing through the State of Cáo and was treated rudely by Duke Gong of Cao. About 630 it was a vassal or ally of Chu. When Chu attacked Song, Jin made a diversionary attack on Cao. After Jin defeated Chu at the Battle of Chengpu in 632 BC, Jin crushed the State of Cao, rescued the State of Song and took Duke Gong of Cao prisoner. After the defeat of the State of Chu, Cao followed the orders of its near neighbour the State of Jin. Later on, the States of Cao and Song became hostile towards each other. Duke Jing of Song captured Duke Dao of Cao in 515 BC and held him prisoner until his death. Thereafter, disorder broke out in Cao and Duke Dao's successors Duke Sheng of Cao and Duke Yin of Cao were killed one after another. Duke Fei of Cao became ruler and betrayed the State of Jin by invading the State of Song. As a result, Duke Jing of Song attacked Cao. No troops from the State of Jin came to the rescue such that the State of Cao was exterminated in 487 BC after the capture of Duke Fei of Cao.

Legacy
