The Chu-Han contention is a post-Qin Dynasty interregnum period in China, during which time the rebel kings derived from the collapse of Qin Dynasty form two camps fighting each other.

One camp is headed by Liu Bang, King of Han, while the other is headed by Xiang Yu, Overlord of the Western Chu.

Several minor kings also fight independent wars against each other during this period.

The war ends with total victory of Liu Bang, who proclaims himself emperor and establishes the Han Dynasty.
