At this time, the state of Qin was still very weak, and its territory had hardly changed compared with the early Spring and Autumn Period. I can't help it, but the countries around him are too powerful, and Qin is remote, and its population and food are not comparable to those around him.
BC 1 and 36 1, before Shang Yang's political reform.
At this time, Qin had just fought a war with Wei. Although the boss of Qin was very capable at that time, it was a pity that the national strength of Qin could not compete with the powerful Wei State. As a result, not only the boss was heartbroken, but also Hexi was taken away by Wei. Even the capital of Qin was afraid of being attacked by Wei, and moved from Liyang to Jingyang.
2. In 36 BC1year, Qin Huiwen became king.
After Shang Yang's political reform, the national strength of Qin was greatly enhanced, and it was no longer the humiliating Qin State. As can be seen from the map, Bashu has been destroyed by Qin, and Yiqu has also surrendered to Qin. Even the original Hexi was taken back from Wei.
3. in 293 BC, the battle of yique.
In order to open the passage eastward into the Central Plains, Qin sent general Bai Qi to fight with Wei, South Korea and the allied forces of the Eastern Zhou Dynasty in Yi Que. The result of the battle is self-evident, and the state of Qin won a great victory. From then on, Qin Jun entered the Central Plains and began the process of competing for the Central Plains.
4. In 279 BC.
Whether in the Spring and Autumn Period or the Warring States Period, Chu was a very powerful country. The vast territory has given him a sufficient population, so Chu is a well-deserved southern hegemon. But unexpectedly, in front of the famous soldier Bai Qi, Chu was defeated and lost a lot of land. From then on, the power of Qin State developed to the hinterland of Chu State, and even the capital of Chu State was exposed to the army of Qin State.
5. In 260 BC, the battle of Changping.
The State of Chu was defeated by the State of Qin, leaving only one State of Zhao, which launched a large-scale war with the State of Qin. But in front of him, not to mention defeating Zhao, even Zhao's 400,000 prisoners were dug and buried. In this case, the unification of the six countries by Qin is just around the corner.
