The Battle of Changping was a massive battle in the late Warring States period, when the two great powers of the time, the State of Zhao and the State of Qin, fought a decisive battle in Changping for the Shangdang region of Korea. In this battle, the Zhao army was killed by the Qin army a total of 450,000 people, directly from a first-class power to a second-rate country, but after the Battle of Changping, the Zhao state still survived peacefully for more than thirty years before being destroyed by the Qin state, and even broke the Yan state, why?
In fact, Zhao Guo can live for more than thirty years and Zhao Guo has broken the Yan Kingdom, and this matter should be discussed separately.
Let's first look at the State of Zhao and the State of Yan, the State of Qin launched the Battle of Handan shortly after the Battle of Changping, but it was repelled by the combined forces of the State of Zhao and the states, but after the Battle of Handan, the strength of the State of Zhao further declined, and the State of Yan in the north saw this situation and moved to take advantage of the fire and robbery. At that time, the relationship between the State of Yan and the State of Zhao had always been good, and King Xi of Yan also sent the chancellor Li Belly to ally with the State of Zhao, but after Li Belly returned to China, he told the King of Yan that the State of Zhao was empty, and just took advantage of the void.
The King of Yan was very moved to hear Li Belly's words, and despite domestic opposition, he brazenly tore up the covenant with the State of Zhao and sent troops to attack Zhao.
Yan Guo's actions greatly angered the soldiers and civilians of Zhao Guo, after all, compared to the enemy, traitors are the most hateful! Moreover, if this battle is lost, then the other princely states will definitely bite Zhao Guo fiercely. Therefore, in the face of the menacing Yan army, the morale of the Zhao state was high, and the enemy was in the same vendetta, and the muzzle of the gun was unanimous to the outside world! Although the number of the Zhao army was not as good as that of the Yan state, but they were all experienced in hundreds of battles, and there was a great prize and a good reputation as the commander, and the combat effectiveness of the Yan army was far inferior to that of the Zhao state, plus this time it was a war without morality, so the morale was weak, and it was quickly repelled by the Zhao state. Lian Po repelled the Yan army, captured the Yan general Le Cheng, and attacked all the way to jicheng, the capital of the Yan state, and the Yan king hurriedly asked for peace, and the compensation for the land was cut before sending away the Zhao army.
Let's look at why Zhao Guo can continue to survive for more than thirty years.
Although the Battle of Changping was won, the Qin state was also a fierce victory, with more than 200,000 dead and wounded by 600,000 Qin troops, and the subsequent Battle of Handan was killed by the combined forces of Zhao, Wei, Chu, and Han, with nearly 300,000 dead and wounded, and it was difficult for the Qin state to launch a large-scale campaign for a long time after the war.
Moreover, after the death of King Zhaoxiang of Qin, the politics of the Qin State was once in turmoil, and three monarchs were changed in just three years.
King Xiaowen of Qin died within three days of his reign, and his son King Xiang of Qin zhuang only succeeded to the throne for three years, until the thirteen-year-old Qin Wang Zheng (Qin Shi Huang) succeeded to the throne, and the throne was stabilized.
However, even though Qin Shi Huang inherited the throne, the power of the Qin state was still in the hands of Lü Buwei, Yan Yi and others, and Qin Shi Huang did not get rid of Lü Buwei and other powerful ministers until the ninth year of Qin Shi Huang (238 BC) and completely controlled the Qin state.
Immediately after taking power, he reused Li Si and others, and began to promote the strategy of unifying the six kingdoms in the eleventh year of Qin Shi Huang (236 BC).
From the death of King Zhaoxiang of Qin to the time when Qin Shi Huang came to power, the State of Qin was busy with internal power struggles and did not use troops on a large scale.
After the State of Qin formally began to unify the Six Kingdoms, the State of Zhao relied on Li Mu to support itself under the iron hooves of the State of Qin for eight years, but after Li Mu's death, Handan was soon captured, and Prince Jia of Zhao fled to Daicheng to claim the title of Daiwang, and survived for another seven years, until the twenty-fifth year of Qin Shi Huang (222 BC) Daicheng was captured by the Qin army, and the State of Zhao was officially destroyed.
In general, although the Zhao Kingdom was seriously injured after the war, but the worms with hundreds of feet died but did not stiffen, and the Yan Kingdom has always been a weak country among the Seven Heroes, and this expedition was also thought out by the King of Yan, and the preparation was not sufficient, which was the reason why the Zhao State was able to break the Yan Kingdom. The reason why the Zhao state can continue to survive for thirty years is mainly in the Qin state, and the losses of the Qin state in these major wars and the turmoil in domestic politics have made the Qin state unable to free up its hands to launch a war, which is the main reason why the Zhao state can continue to survive.
