Western Han (202 BC – 9 AD)
China's first imperial dynasty was the Qin dynasty (221–206 BC). The Qin united the Chinese Warring States by conquest, but their regime became unstable after the death of the first emperor Qin Shi Huang. Within four years, the dynasty's authority had collapsed in a rebellion. Two former rebel leaders, Xiang Yu (d. 202 BC) of Chu and Liu Bang (d. 195 BC) of Han, engaged in a war to determine who would have hegemony over China, which had fissured into Eighteen Kingdoms, each claiming allegiance to either Xiang Yu or Liu Bang. Although Xiang Yu proved to be an effective commander, Liu Bang defeated him at the Battle of Gaixia (202 BC) in modern-day Anhui. Liu Bang assumed the title of Emperor at the urging of his followers and is known posthumously as Emperor Gaozu (r. 202–195 BC). Chang'an (modern Xi'an) was chosen as the new capital of the reunified empire under Han.
