The Qin Dynasty was also China's first feudal empire, and Qin Shi Huang proclaimed himself emperor and was the first emperor of China. The first country to be destroyed by the Qin State was Korea, and the last country to be destroyed was the Qi State. The following is a timeline of Qin's domination of the world:

In the seventeenth year of the reign of King Qin (230 BC), the Korean general Nei Shi Teng led the Qin army to destroy Korea, captured Han Wang'an, and Han died. The obtained Korean land is located in Yingchuan County.

In the nineteenth year of the reign of King Qin (228 BC), Wang Jian of the Qin army invaded Handan, the capital of Zhao State, and Zhao Wangqian was forced to surrender to Qin, Zhao Po, and placed Handan County, Julu County, and Taiyuan County. Zhao Gongzijia led 100 members of his clan to flee to Daicheng.

In the twentieth year of the reign of King Qin (227 BC), Prince Dan of Yan sent Jing Ke to assassinate the King of Qin, which was known as "Jing Ke's assassination of Qin", and the King of Qin immediately sent Wang Jian to lead his troops to attack Yan.

In the twenty-first year of the reign of King Qin (226 BC), Wang Jian attacked Yandu Ji, and Yan Wangxi retreated to Liaodong and killed the prince Dan in order to seek peace.

In the twenty-second year of the reign of King Qin (225 BC), Wang Ben led an army of 100,000 to attack Wei, besiege the Wei capital Daliang, and divert water from the Yellow River chasm to irrigate Daliang. Three months later, the city of Daliang was broken, the king of Wei faked surrender, and Wei died.

In the twenty-second year of the reign of King Qin (225 BC), Wang Jian led an army of 600,000 to attack the state of Chu.

In the twenty-third year of the reign of King Qin (224 BC), Wang Jian led an army of 600,000 to cross the Huaishui and besiege Shouchun, the capital of Chu.

In the twenty-fourth year of the reign of King Qin (222 BC), the Chu army was demoralized and lacked food and grass, so it withdrew from the front. Wang Jian took the opportunity to pursue, eliminated the main force of the Chu army, occupied the Chu capital Shouchun, and captured the king of Chu. The Chu people reinstated Changping Jun as king. Wang Jian led the army to cross the Yangtze River, pacified the south of the Yangtze River, placed Huiji County, and died in Chu.

In the twenty-fifth year of the reign of King Qin (222 BC), Wang Ben conquered Liaodong and captured Yan Wang Xi, and then conquered Daicheng and captured Zhao Dynasty Wang Jia. Yan and Zhao were completely destroyed, and Qin Shi Huang set up Yanmen County in the Daidi.

In the twenty-sixth year of the reign of King Qin (221 BC), Wang Ben led his army south to attack the state of Qi.

At this point, Qin unified the world and became the first feudal unified country in Chinese history.
