Why was the Qin Empire able to unify China?

Objective reasons: After the long-term war of the Spring and Autumn Period and the Warring States Period, people have become tired of war and yearn for peace.

The war policy was wrong, and several countries of the Warring States period failed to unite against Qin, but adopted a foreign policy of ceding land and seeking peace.

The inevitable consequence of historical trends.

Subjective reasons: The Qin Dynasty was economically strong after the Shang Dynasty reform.

The policies of the Qin Dynasty were correct. Break the union of the nations and break them individually.

Qin Shi Huang's personal eloquence is strategic.

PS: This kind of cause-type questions, especially in history, have a routine, such as:

Mainly from the subjective reasons and objective reasons; These include agriculture, industry, economy, historical background, individual talents, economic policy, ethnic policy, ethnic status, transportation situation, etc. - Do more subjective questions about history, and you will find common ground if you summarize them.

1.The trend of the times is that if you divide for a long time, you will be together, and you will be divided for a long time.

2.The Qin state was strong, surpassing the other six countries and had a unified capital.

3. Qin Shi Huang is eloquent, far-sighted, and has high personal comprehensive quality.

4.The Qin State is full of talents, many generals and generals, and generals such as Wang Jian and Meng Tian use soldiers like gods.

5.The broad masses of the people yearn for an end to the war and a happy and stable life.

6.The political and economic systems of the other six countries lagged behind those of Qin.

People always think that the Qin State is backward.

In fact, Qin's science and technology are quite advanced, and the equipment has been standardized and produced.

Carry out legalist reforms, enrich the country and strengthen the army, and finally unify the six countries by force.

Personally, I think that the most important thing is that it was the first to adopt the iron plough and ox ploughing, and then there is the Shang Yang reform.

1. After a long period of scuffle, the people yearn for reunification.

2. Shang martingale method.

Later, Qin's strength increased greatly and realized the prosperity of the country and the strengthening of the army, which was the fundamental reason.

3. Ying Zheng's eloquence and strategy.

4. Adopt correct and flexible strategies, such as long-distance and close attack.

Qin Shi Huang Ying Zheng (259 BC - 210 BC), Ying surname, Zhao, Ming Zheng (a name "Zheng"), also known as Zhao Zheng, Zulong.

In 221 BC, after Qin unified the six kingdoms, King Yingzheng of Qin thought that he was "virtuous and three emperors, and meritorious to the five emperors", so he adopted the title of "emperor" of the three emperors and the "emperor" of the five emperors to form the title of "emperor", and was the first monarch in Chinese history to use the title of "emperor", so he called himself "the first emperor".

The Qin Dynasty unified the world with Qin Shi Huang.
