The two wars that decided the rise and fall of the Qin Dynasty were

Absolutely disagree that the prosperity of the Qin Dynasty relied on the Battle of Changping, first, the Battle of Changping was launched by the Qin State, not the Qin Dynasty. Second, the Battle of Changping only eliminated the main force of Zhao and reduced the resistance of Qin's unification war. After the establishment of the Qin Dynasty, there was no war, and it was the old aristocratic forces of the Six Kingdoms that started the war.

In the war to destroy the Qin, the battle of playing in the water that delayed the fall of the Qin Dynasty. The Battle of Julu, which struck the main force of the Qin Dynasty's Northern Route Army, could be a key battle for the defeat of Qin.

An important battle to unify the Six Nations, the Battle of Changping. The key to the defeat of the Patriotic Empire was the Battle of the Giant Deer.

The first time was the Battle of Changping, when the obstacle to the unification and hegemony of the Qin State was the Exit and Zhao State, the 400,000 army of the Zhao State against the 200,000 Qin State, and as a result, Zhao Kuo talked about the army on paper, and killed the 400,000 army of the Zhao State in a pit.

The second time was the battle of Julu, Xiang Yu led the princes of the world to oppose Qin, in Julu, the princes of the world were all watching from the wall, not daring to fight with Zhang Han's 400,000 Qin army, Xiang Yu with 100,000 troops, broke the cauldron and sank the boat, defeated Zhang Han's 400,000 Qin army, until Xianyang, the Qin State perished.

Battle of Changping. Battle of the Great Deer.

The Battle of Changping, so it led to the decline of the strength of the Zhao State and accelerated the unification of the Qin State, which was a very important war.

The Battle of Changping determined the development between the Qin and Zhao states, and also led to the decline of military power, as well as the decline of the country's economy.

The Battle of Annihilation. Historical records: In this battle, the Qin army adopted the strategy of avoiding the real and attacking the weak, and attacked on the flank, and easily defeated the Qi State.

Qin's battle was like a bamboo, and victory was an inevitable result. However, it is worth mentioning that when the Qin army destroyed Qi, it learned the lesson of destroying Chu and ignoring the enemy's defeat, avoided the front of Qi, went south from Yan, took advantage of the weakness, and went straight to Linzi, which caught the Qi people off guard, so they successfully completed the task of destroying Qi. At this point, Qin all destroyed the six kingdoms of Zhao, Han, Yan, Chu, Wei, and Qi, unified China, and established the first highly centralized feudal state in Chinese history.

There was no decent battle in the later period of the destruction of the Six Kingdoms The battle to destroy Chu was the final battle - the symbol of unification can be regarded as the emperor In fact, by the end of the Second Dynasty, the Qin Dynasty still had an army attacking the Hetao and a South Vietnamese in Nanping.

So unity in the strict sense of the word, you don't have a territory to measure.

The Zhou Dynasty was not a nation-state, and it didn't say that it was definitely yours, but it hadn't been unified yet, and if it wasn't for Chu and Han, maybe it would have to go on after fighting the Vietnamese Hetao.

The Battle of Qin, Zhao and Changping is what the history textbooks say.

The battle to destroy the state of Chu, the battle of Qin and Zhao Changping.

The most important thing is, of course, the Battle of Changping, and if you make a tabloid, you can do it around this content.
