The Uprising of Chen Sheng and Wu Guang
In 210 BC, Qinshihuang died during an inspection tour. His second son, Hu Hai, succeeded to the throne.
In 209 BC, over 900 poor peasants drafted to guard the boundaries were delayed by rain in Dazexiang (southwest of today's Suzhou in Anhui Province) on their way to their posts. According to the harsh Qin laws, they faced the death penalty, and in desperation, led by Chen Sheng and Wu Guang, they killed the officers escorting them, and rose in revolt. This was the beginning of China's first great peasant uprising.
The revolt spread, and Chen Sheng proclaimed himself emperor. The deaths of Chen Sheng and Wu Guang by treachery and the defeat of the rebels when they were almost at the gates of the capital, Xianyang, gave the second Qin emperor a breathing space.
