秦二世
During this time, Li Si and Zhao Gao fell out, and Li Si was executed. Zhao Gao decided to force Qin Er Shi to commit suicide due to Qin Er Shi's incompetence. Upon this, Ziying, a nephew of Qin Er Shi, ascended the throne, and immediately executed Zhao Gao. Ziying, seeing that increasing unrest was growing among the people and that many local officials had declared themselves kings, attempted to cling to his throne by declaring himself one king among all the others. He was undermined by his ineptitude, however, and popular revolt broke out in 209 BC. When Chu rebels under the lieutenant Liu Bang attacked, a state in such turmoil could not hold for long. Ziying was defeated near the Wei River in 207 BC and surrendered shortly after; he was executed by the Chu leader Xiang Yu. The Qin capital was destroyed the next year, and this is considered by historians to be the end of the Qin Empire. Liu Bang then betrayed and defeated Xiang Yu, declaring himself Emperor Gaozu of the new Han dynasty on 28 February 202 BC. Despite the short duration of the Qin dynasty, it was very influential on the structure of future dynasties.
