Why was it Qin that unified the Six Kingdoms in the end? What are the advantages of the Qin State?

The reasons for Qin's ability to unify China and the historical status of the Qin Dynasty should be explored from both objective needs and possibilities.

l) Ending the situation of separatism among the princes and completing the unification of the feudal state is the inevitable trend of historical development since the Spring and Autumn Period and the Warring States Period.

From an economic point of view, due to the increase in productive forces and social and economic development, the ties between various localities have been strengthened, and this has provided the material conditions for reunification.

During the Warring States Period, most of the vassal states abolished the feudal system and implemented the county system, and partially implemented the first-class centralized system, thus laying a political foundation for the unified feudal state.

In terms of ethnic relations, the ties between various ethnic groups have been strengthened day by day, and a fairly consolidated ethnic community has been formed with the Chinese nationality as the center.

The broad masses of the working people yearn for reunification.

The long-term war for hegemony has formed a partial unity.

2) From the perspective of the Qin state, it has the strength to complete unification.

The social reform of the Qin State was relatively thorough, and a relatively consolidated centralized feudal state was established.

The new landlords of the Qin State were powerful, the economy developed rapidly, and the army was strong in combat.

The Qin State implemented correct strategies such as distant friendship and close attack.

Qin Wang Yingzheng himself is eloquent. Qin has the subjective and objective conditions to complete reunification.

Reasons: (1) The reunification of the six countries conforms to the trend of historical development and the strong demands of the broad masses of the people.

2) The Qin State increased its national strength through the Shang Dynasty Reform Law, realized the prosperity of the country and the strengthening of the army, and laid the foundation for the unification of the six countries.

3) Qin Shi Huang reused talents and promoted the arrival of unification.

4) Qin Shi Huang himself is eloquent.

There are many reasons for this, and here are a few of them:

1. The system of the Qin State: The Qin kings of the past dynasties dared not to select talents from the Qin heart. Later, Shang Ying changed the law, stipulating that merit should be evaluated by achievements or production achievements, breaking the hereditary system of the Spring and Autumn Period and the Warring States Period at that time, and formulating strict laws to make the entire Qin State operate effectively and at high speed.

2. The geography and folk customs of Qin: At the beginning of the founding of Qin, the invasion of Xirong made the people of Qin brave and good at war. And it is located in a remote area, and for a long time after the assessment of Xirong, it did not participate in the war in the Central Plains, and the country continued to develop and accumulated a strong foundation.

The Qin State occupied the Wei River Valley, which was relatively fertile, and created favorable conditions for the development of the agricultural economy.

3. The disagreement of the six countries: This is the reason for the complete failure of the joint plan, which means that it is difficult for the six countries to work together to resist Qin.

The rest is a few key battles, such as the Battle of Changping, which destroyed the elites of various countries; There is also a plan to attack from afar, first stabilize the Qi State, then destroy the Five Kingdoms, and finally the Qi State will naturally perish.
