Why did the Qin State win the last world?

Because the Qin State has the determination to unite from top to bottom and comprehensive national strength.

Because the earliest change in the Qin State was the Shang Dynasty reform.

He recognized the private land system, a large area of mines, and bribed other countries with money to grow food for him, and used this to buy people's hearts. Coupled with the superior geographical location, it attaches great importance to agricultural water conservancy projects.

Slowly accumulate strength, wealth, and finally be good at employing people, be good at accepting new things, and implement the policy of five vertical and three horizontal, and each one is broken.

And Qin Shi Huang's talent, ambition, and so on.

Iron tools were used in farming.

Located on the edge. Shang martingale change.

Qin Shi Huang is awesome.

A sentence in "On the Passage of Qin" explains very clearly - "Those who destroy the Six Kingdoms are also the Six Kingdoms, and the Six Nations are not Qin" Internal factors are always the most important At that time, Qin's national strength was not absolutely stronger than the other six countries, especially some big countries, it was the six countries themselves that defeated themselves, and Qin just launched the right war at the right time.

Both the economy and the military were the most powerful at the time. If it is not unified, there will be no reason!

Because the six countries are sometimes horizontal and sometimes vertical, capricious, only looking at the present, plus the Qin people since the Shang Dynasty, there is a military industry knighthood system, the Qin family is still martial, like a tiger and wolf on the battlefield. Then there is the fact that the Qin people still cultivate water conservancy and attach importance to agriculture. Zhengguoqu became a fertile field in Guanzhong, and Dujiangyan made Sichuan a heavenly mansion, which played a key role in the annexation of the Six Kingdoms.

Usually we position Qin to destroy the six countries to unify the world, this time to reach the peak, but in fact the Qin Dynasty still continued to fight, immediately launched a large-scale war against the Xiongnu and South Vietnam, the first peasant uprising Chen Sheng Wu Guang peasant uprising or hail is because Qin conscripted Chen Sheng, Wu Guang and other more than 900 soldiers were conscripted to go to Yuyang Garrison, on the way in Qi County Daze Township (now Suzhou) for heavy rain blocked, can not reach the destination as scheduled, in a hurry, Chen Sheng, Wu Guang led the soldiers to kill the escort of the soldiers, launched a mutiny. The Qin Dynasty's successive foreign wars greatly depleted the national strength and were also the direct cause of the peasant uprisings.

However, the Qin Dynasty did not fall to the peasant uprising, but the remnants of the aristocracy took advantage of the peasant uprising to start an armed rebellion, for example, behind Xiang Yu was the remnants of the Chu State, and Peng Yue used part of the remnants of the Wei State.

The accidental death of the first emperor of the Qin Dynasty led to a sharp division within the transfer of power, and the power was seriously depleted, and finally the Qin Dynasty died in internal and external troubles. Qin Shi Huang did not die, most of the remnants of the Six Kingdoms did not have the courage to resist, and Hu Hai registered through improper means, so he couldn't suppress the people below at all.

A Fang Gong Fu said: The Qin family, Qin, not the world. The main problem of the Qin Dynasty is still the problem of internal decision-making, the agricultural civilization society, the productivity is limited, and the limited resources are invested in continuous war, which often leads to the collapse of the dynasty, such as the social turmoil in the later period of Emperor Wu of the Han Dynasty, and Yang Guang of the Sui Dynasty is similar, the fundamental reason is that the productivity is low, and the war income cannot make up for the expenditure.
