The Warring States period was a period of major changes in China's history, when the princes competed for power and hegemony, and finally the Seven Heroes of the Warring States appeared. The Warring States period is also a period of controversy among a hundred schools of thought, and various types of changes and the development of war strategies have made this period of Warring States the most prosperous period of civilization achievements in China's history, and the strength of the Seven Heroes of the Warring States at this time is very stable, and finally the Qin State unified the world, ending this period of war.
Some historians have asked who was the strong opponent who could compete with the Qin state during the Warring States period?
The seven warring states are Qi, Chu, Yan, Han, Zhao, Wei, and Qin, according to the "Records of History", there were more than one hundred and forty princely regimes in the Spring and Autumn Period, and with the unfolding of the division situation, more than twenty eventually survived, and in the early days, the four regimes of Qi, Jin, Chu, and Yue were the most prosperous, and later with the rebellion of the Jin state, the princes competed with each other, and the Yan state at this time was the most powerful. Gradually, the princely states began to reform the system, and at this time, the Qin state developed rapidly after the Shang martingale transformation law, the country was rich, the army was strong, and the hegemonic position was laid in the struggle with the State of Qi. However, at this time, the military strength of the Zhao state was greatly enhanced, and the method of warfare of riding and shooting was implemented, and with the help of Lin Xiangru and Lianpo's ministers, it became the biggest obstacle to the unification of the Qin state.
Unification of the world should be the dream of every princely state in the Warring States period, with the outbreak of war, the Qin state has robbed the city all the way, invincible, at this time several countries are unwilling to submit to the Qin state, so they turned to the Zhao state with the strength of the Qin state, and since then the Zhao state has become a thorn in the eyes of the Qin state. There have been several large-scale wars between Qin and Zhao, of which the Battle of Changping is the most famous battle, and it is also the largest and earliest war in China's history. In the Battle of Changping, the most powerful general of the State of Zhao, Lian Po, led the army to meet the battle, at this time the State of Qin heard of Lian Po's fame, so it used treacherous tactics to confuse the King of Zhao, and replaced the inexperienced Zhao Kuo at the beginning of the war, and finally the qin state won the war, and the Qin general Bai Qi killed all the 400,000 Zhao troops who came to surrender. However, the defeat at the Battle of Changping did not cause the Zhao state to lose confidence, and it still vowed to die against the attack of the Qin state.
The State of Zhao still refused to concede defeat in the face of the attack of the State of Qin, and was unwilling to cede the territory of the State of Zhao to the State of Qin, which caused the later famous Battle of Handan. The Zhao army was surrounded and suppressed by the State of Qin in the Battle of Handan, and all the food and equipment were exhausted, and it was finally the reinforcements of the State of Chu of Wei that saved the State of Zhao. In the subsequent wars, the situation in which the Qin state and the Zhao state were on a par with each other was not broken, until the arrival of the war in which the five countries jointly attacked Qin broke the entanglement between Zhao and Qin, and in history, only the Zhao state could compete with the Qin state for such a long time, and after two major battles, it was willing to yield, and the Zhao state was also very powerful. In 222 AD, the king of the State of Zhao was captured by the State of Qin, and the State of Qin unified the world, ending the Warring States period.
Someone once said that if in the war in which the five kingdoms jointly attacked Qin, the Chu army did not take the opportunity to escape, then did the situation in the world change?
