From 230-221 BC the Qin's wars of unification took place and they were a series of military campaigns launched in the late 3rd century BC by the Qin state against the other six states- Han, Zhao, Yan, Wei, Chu, and Qi.
In 215 BC the leader of the Qin dynasty ordered one of the generals to set out against the Xiongnu tribes. The leader, Qin Shi Huangdi believed that the Xiongnu were a threat to the Qin dynasty. He wanted to expand his territory. The general assigned for the job was Meng Tian. He managed to defeat the Xiongnu and drove them out of the Ordos region. The defeat made the leader of the Xiongnu, Touman, to flee to the Mongolian Plateau. This whole event caused the General Meng Tian to get a wall built which is known as 'The Great Wall of China' because he felt that China was not a protected as they thought it was.
In 214 BC, the Qin dynasty began a military campaign that's goal was to take over the territories of what is now southern China and north of Vietnam. The land was however, jungle land and the Chinese army were not accustomed to such environment. They were defeated by the southern tribes guerrilla warfare. They did, however, build a canal in the south through which they transferred ammunition. This enabled them to capture Guangzhou and took the provinces of Fuzhou and Guilin.
In 209 BC, there was the first uprising against the Qin rule. This was the follow up of Qin Shi Huangdi's death. This was called the Dazexiang uprising. It was lead by Cheng Sheng and Wu Guang who were both civilians. They were going to their work when the there was rain and flood. They knew that they would never be able to make to work in time. So, they took it upon themselves to stand up against the Qin laws that stated that anybody who was late to government jobs, would be executed. They were considered the Kings of the people who were ready to rebel against the Qins. However, they were no match for the highly professional Chinese fighters. They both died in the war, Cheng was betrayed by his guard, and thus assassinated. Wu was victim of infighting.
In 207 BC, the Battle of Julu was fought in Julu between the Qin dynasty and the state of Chu. The leaders were Zhang Han, of Qin, and Xiang Yu of Chu. The Chu won and the event marked the decline of the Qin's military power. This was a great victory for the Rebels against the Qin dynasty. Zhang Han had sent his men to conquer and fight against the rebel states. They began to set out to attack the rebel state Zhao, they wanted to besiege its capital, Handan. Zhao's leader requested for protection from the King Huai of Chu and his request was granted. He dispatched two armies, one led by Song Yi and the other by Liu Bang. The armies were meant to go on to take over the Qin capital Guanzhong. Song Yi ordered his army to stay in Anyang for 46 days. On the 47th day, Xiang Yu, who was the deputy of Song Yi's army, burst into the tent and killed him, with the claim that Song Yi was a traitor. Xiang Yu became head of the army. Xiang Yu's troops were fierce in battle and soon they beat the Qin army. The Qin leader, Zhang Han, surrendered alongside his deputies and 200,000 other men. The fallen Qin empire was, on Xiang Yu's orders, divided into eighteen kingdoms.
