The states of Qin and Chu have always been inseparable, what caused them to have a great war?

At the beginning, the relationship between Qin and Chu was very good, just like the two brothers, it can be said that the scales are inseparable from the scales, and the scales are not separated from the scales, but with the changes of the times, the relationship between the two countries has gradually changed, and finally evolved into a great war, in fact, the reason is also very simple. First of all, because of the struggle for land, from ancient times to the present, no matter what dynasty has attached great importance to land, so the battle for land is the beginning of the war between the two countries. Secondly, both countries want to dominate the world, and since they have conflicting interests, then a major war is inevitable.

At the beginning of the Spring and Autumn Period, Qin and Chu were very good allies, and the two countries called each other brothers, with Chu as brothers and Qin as brothers. The relationship between the allies of the two countries lasted for hundreds of years, and that was because they had common enemies, the Jin State and the Wei State, and if the two of them did not align, it was very likely that they would be broken by other countries one by one, after all, the enemy's enemy was a friend, so the two countries were helping each other, and there was no reason to fight at this time. Moreover, the continuous marriage between Qin and Chu has made their relationship better and better.

But when two countries have conflicting interests, there is no reason to avoid a big war between them. With the rise of the Qin State in the middle of the Warring States Period, irreconcilable contradictions emerged between the two countries. Because in the late Spring and Autumn Period, Qin helped Chu recover its homeland and restored Chu, so that Chu could restore it, so Chu gave the land of Shang Yu to Qin to repay their kindness for helping them restore their country.

At this time, the state of Chu had just been restored, and its strength was definitely inferior to that of the Qin state, so it was natural to give it to the Qin state.

But as time passed, the state of Chu slowly gained a firm foothold and became more willing to take back this place, but the state of Qin was definitely unwilling to return this piece of land to the state of Chu in vain. The rift between the two countries gradually deepened, and this point was taken advantage of by Zhang Yi to provoke a war between the two countries, making the alliance between the two countries completely become a piece of waste paper.

Qin Chu was originally a very good partner, but there were three places that became their points of conflict, namely Danshui Hanshui and the Yangtze River. These are all very beneficial to the Qin state, because the Qin state is upstream and the Chu state is downstream. Later, the Battle of Qinchu Danyang and the Battle of Lantian occurred.

The state of Qin and the state of Chu have always been inseparable from each other, because of the greed of King Yingzheng of Qin, and the state of Qin hopes to rule the six countries.

On the one hand, in the Qin-Chu conflict area, the people of Chu who had regained strength were unwilling to be controlled by Qin, and on the other hand, Qin's defense against Chu was no longer defensive but offensive, and these various reasons led to their great war.

Because Chu felt that only in this way could it better defend its national territory and defend its national sovereignty.

Because Chu is not a fool, they understand that if they don't fight against Qin, after Qin destroys other countries, Qin's next target will be Chu.

Each country has its own development, leaving different traces in history, among the seven countries, the officials of Qi are the most stable and peaceful, and the people's lives are also the most prosperous and healthy, and Zhao has always been a military power, two of the four generals of the Warring States are in Zhao, so Zhao's frontier has always been the most stable, and he has always been considered a big country that can be compared with Qin, each country has its own area of expertise, otherwise it will not be able to obtain a stable position in the competition for vassal states, Qi heavy economic development, Zhao is a military power, and Chu is not idle, It can be regarded as a traditional power in the Warring States period.

1. The unification of the Qin State in the Sixth Central and Kuan Kingdom was due to the Shang Dynasty reform, and after the Shang Dynasty reform, the Qin State gradually became stronger and became the most powerful prince in the west.

2. In 356 BC, Shang Ying, with the support of Qin Xiaogong, presided over the reform of the Qin State. The drastic implementation of social changes violated the interests of the slave owners and aristocrats, and Shang Ying lost his backer after the death of Qin Xiaogong, and was finally killed by a car split. However, the sale was cautious and bright, and Shang Ying's changes were continued.

3. The state of Chu went to extinction, because there was no virtuous monarch and no drastic reforms in the later period of the Chu state.

One, fighting against the water, either you die or I die.

Second, the coach was decisive and only brought three days of food to the battlefield in person.

Third, the Chu army was high-spirited, the Qin army was indecisive, and morale prevailed.

Fourth, most of the Chu army was a civilian, and they were always oppressed by the officers in the past, and they had hatred in their hearts.

Mortal Heart.

The bitter hatred of the state of Chu for the state of Qin.

Although Xiang Yan said that Chu had three households, Qin was better than Chu.

The soldiers thought in their hearts that if you don't die, we will die, in other words, as the saying goes, you are playing with your life.

There is a determination to win and a heroic performance of the warriors.

Xiang Yu is brave and strategic, decisive at the moment, and determined to win.
