Chu–Han Contention
Between 206–202 BC, a power struggle for supremacy over China (historically known as the Chu–Han Contention) broke out between Xiang Yu and Liu Bang. Liu Bang used Emperor Yi's death as political propaganda to justify his war against Xiang Yu. In 205 BC, he held a three-day memorial service for the emperor, accused Xiang Yu of committing regicide, and rally support from the people against Xiang Yu. In 202 BC, the Chu–Han Contention concluded with victory for Liu Bang, who became the sovereign ruler of China and established the Han dynasty. Liu Bang ordered his generals Zhou Bo, Wang Ling and Fan Kuai, who had been enfeoffed as marquises, to conduct memorial services for Emperor Yi in their respective marquisates.
