What is the main reason why Qin became the most powerful feudal state of the Warring States Seven He

Mainly because of the success of the Shang Martingale Reform.

In 356 BC, Shang Ying, with the support of Qin Xiaogong, began to change the law. The decree stipulates that the state recognizes the private ownership of land and allows free buying and selling.

Those who are rewarded for ploughing and warfare and produce more grain and cloth are exempt from forced labor. Titles and fields were awarded according to the size of military merit, and the privileges of the old nobles who had no military merits were abolished. Establish a county system, which is governed by officials directly sent by the monarch.

After the Shang Dynasty reform, Qin's economy developed, the combat effectiveness of the army was continuously strengthened, and it developed into the richest and most powerful feudal state in the late feudal period.

In the late Warring States period, the powerful Qin State continued to annex the lands of the eastern countries through wars. Since Qin's victory over Zhao in the Battle of Changping in 260 BC, the Six Eastern Kingdoms were no longer able to resist the Qin army's attack.

The main reasons are long-distance and close attacks, Shang Ying's change of law, the appointment of powerful generals, and the destruction of the Six Kingdoms.

Reform! Qin's military system! You know?

In the Qin State at that time, if there was a family member to be a soldier, the treatment was very good. If a soldier cuts off the enemy's head and brings it back, he will be given a prize! If you fight bravely, the better your family's status and life!

Therefore, all the soldiers of the Qin State are very brave and good at fighting!

That is to take the lead in implementing the new policy, implementing reforms, and enhancing national strength.

Answer A: This question examines the Shang Dynasty reform, through this reform, the Qin State has become rich and strong, and the national strength has increased greatly, laying a solid foundation for the future annexation of the Six Kingdoms, so A is chosen.

Yes, the strength of the Qin State was particularly strong, and the managers of the Qin State at that time were particularly powerful, and their country's military strength was also very strong at that time.

The strength of the Qin State is very strong, because the monarch of the Qin State has a very smart mind, and the military strength is also very strong.

Yes, the Qin State has always wanted to unify the six countries, and they are very developed in the military, cultural and political fields, and they have many excellent people.

The Seven Heroes of the Warring States have strong strength, and the reason why the Qin State unified the Six Kingdoms in the end was because the Qin State had unique geographical advantages, and at the same time adopted a talent policy of embracing all rivers, and the Qin State at that time had developed a highly centralized feudal system, which was far ahead of the other six countries in terms of system.

In the Warring States Period, there were seven of the most powerful vassal states, known as the Seven Heroes of the Warring States, each dominating one side, these countries have been attacking each other, but no one has the strength to destroy each other, until with the rise of the Qin State, the other six countries gradually felt the threat brought by the Qin State, and began to join forces to resist the Qin State, but in the end, because of different interests, they were divided and disintegrated by the Qin State, and broke them one by one. The establishment of the powerful Qin Empire, at that time other countries were not without the opportunity to dominate, for example, Zhao State once became the most powerful country because of the Hufu cavalry and archery reform of King Zhao Wuling, but it declined rapidly due to civil strife, and the following is an analysis of why only Qin finally dominated the Seven Heroes of the Warring States:

1. Unique geographical location

Qin has a unique geographical location relative to the rest of the six countries, Qin is located in the Guanzhong region, the land of the four stops, easy to defend and difficult to attack, the six countries attacked the Qin State many times because the Qin State occupied the geographical advantage and finally returned in vain, plus the Qin State built the Zhengguo Canal, the Guanzhong Basin became a fertile field for thousands of miles. It also provided a steady stream of food for the Qin State.

2. Advanced political system

After the reform of the Shang Dynasty, the Qin State has been far ahead of the other six countries in terms of political system, and has become a highly centralized feudal state, with high administrative efficiency, and the Qin State adopted the talent strategy of embracing all rivers, the Shang Yang who changed the law was a native of the Wei State, and the killing god Bai Qi was promoted from ordinary soldiers.

The Qin State implemented the Shang Dynasty Reform, and there were many powerful generals and strict monarchs, so they were able to unify the world.

Strengthen the centralization of power, rectify the army, ** cannot be hereditary, only promoted by military merit.

In the last years of the Zhou Dynasty, when the slavery system collapsed, the Qin State took the lead in completing the transformation from a slave society to a feudal system.

In many ways, Qin's economy was more developed than the other six countries, and the Shang Dynasty also played a role in it, and Qin advocated Legalism; The personal charm of the emperor of Qin, this is not only Qin Shi Huang, but also the successive emperors of Qin have the ambition of war, which is reflected in Jia Yi's "On the Passage of Qin". There is also the military strength of the Qin state, which is inseparable from his economy, after all, the economy is the foundation. In addition, the geographical location of the Qin Dynasty has its advantages, and there is a general trend of history, the world must be divided for a long time, and it must be divided for a long time, and the Warring States Period has been in war and strife for many years, and there are always strong countries that will gradually annex weak countries, which is the trend of the times, and also reflects the law of natural selection.

The superiority of the system enables the rapid development and improvement of productivity. If you are poor, you will change, and if you change, you will be able to do it for a long time.

Second, it is necessary to persist in changing the law, so that the advantages can be preserved and political affairs can be carried out in a stable and orderly manner.

It is the clan again, and the martial spirit and perseverance and simplicity cultivated by years of fighting and surviving in the sea of blood provide the foundation for the conquest of the world.

Finally, the geographical advantage, although the closed geographical environment is not conducive to trade exchanges, it allows the Qin state to survive at the most critical moment. Then the rear can be attacked, and the retreat can be defended.

It can be seen that people are the key. The king of Qin dared to use people, could use people, and made good use of people, so people made the best use of them, and everyone wanted to use them, so that the law could be changed, things could be done, and the land could be kept.

Shang Ying's law, many generals, geographical advantages, and soldiers.

Qi State, Qi State (1044 BC - 221 BC), the Zhou Dynasty vassal state, is a vassal state in Chinese history from the Western Zhou Dynasty to the Spring and Autumn Period and the Warring States Period, was named a marquis by Zhou Tianzi, and was divided into two eras, Jiang surnamed Lü Qi and Tian Qi. The territory is located in present-day Shandong.

In 265 BC, after the death of King Qi Xiang, his son Tian Jian ascended the throne, and his mother was assisted by the queen. In 249 BC, after the death of the queen, the queen's younger brother Hou Sheng reigned.

Hou Sheng was greedy, and under the constant bribery of the Qin State, Qi Wangjian listened to Hou Sheng's proposition, stood by and watched the other five countries, and did not strengthen war preparedness. Finally, after the fall of the Five Kingdoms, the King of Qi suddenly felt the threat of the Qin State, and hurriedly gathered his army to the western border, preparing to resist the attack of the Qin army.

In 221 BC, after the destruction of Han, Zhao, Wei, Chu, and Yan, the king of Qin ordered Wang Ben to lead the Qin army to attack Qi on the grounds that Qi refused to visit Qin, and the king of Qi ordered the main force of the Qi army of 400,000 to gather in the west in a hurry, and the Qin army avoided the main force of the western part of the Qi army, and went south from the original southern Yan State to Linzi, the capital of Qi.

The Qi army was caught off guard by the sudden attack of the Qin army from the north and collapsed. The king of Qi built a city and surrendered, and the state of Qi perished. So far, the Qin State has unified the world.

The last one to perish was the state of Qi.

In 230 BC, Korea fell.

In 229 BC, the state of Zhao fell.

In 225 BC, the state of Wei fell.

In 225 BC, the state of Chu fell.

In 222 BC, the Yan Kingdom fell.

In 221 BC, the state of Qi fell.

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, and Wang Jian of Qi surrendered without a fight and died in Qi. So far, Qin has destroyed the six countries and ruled the world.
