Fall from power

Three assassination attempts were made on Qin Shi Huang, leading him to become paranoid and obsessed with immortality. He died in 210 BC, while on a trip to the far eastern reaches of his empire in an attempt to procure an elixir of immortality from Taoist magicians, who claimed the elixir was stuck on an island guarded by a sea monster. The chief eunuch, Zhao Gao, and the prime minister, Li Si, hid the news of his death upon their return until they were able to alter his will to place on the throne the dead emperor's most pliable son, Huhai, who took the name of Qin Er Shi. They believed that they would be able to manipulate him to their own ends, and thus effectively control the empire. Qin Er Shi was, indeed, inept and pliable. He executed many ministers and imperial princes, continued massive building projects (one of his most extravagant projects was lacquering the city walls), enlarged the army, increased taxes, and arrested messengers who brought him bad news. As a result, men from all over China revolted, attacking officials, raising armies, and declaring themselves kings of seized territories.

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.
