After Liu Bei took Hanzhong, he made a big mistake and laid the foundation for the demise of Shu Han
Introduction: The establishment of the Shu Han during the Three Kingdoms period can be described as very difficult, although Liu Bei has the so-called Han blood on his body, but because of its age, it has not been recognized, and when he was young, he could only live by selling straw shoes. After the outbreak of the Yellow Turban Rebellion, he keenly felt that the world was about to be in chaos, so he quickly responded to the call of the government to recruit troops to recruit yellow turban thieves, and also accumulated some merits on the battlefield. After Dong Zhuo's chaos in Beijing, he joined the anti-Dong alliance with Gongsun Zhan, because he was very active, and soon after the dissolution of the alliance, Tao Qian handed over Xuzhou to him, and liu Bei began to embark on the road to world domination. After decades of southern conquest and northern warfare, shu han was established with the help of Wolong Fengchi and many people. Perhaps what Liu Bei did not know was that after he took Hanzhong, he also made a big mistake, laying the foundation for the demise of Shu Han.
After the Battle of Chibi, Liu Bei successfully occupied Jingzhou, and according to Zhuge Liang's strategic plan, after obtaining Jingzhou, he began to plot Yizhou, so Liu Bei marched into Yizhou in the name of helping Liu Zhang attack Zhang Lu in Hanzhong, and the dim-witted Liu Zhang was Liu Bei's opponent? Liu Bei easily took all of Yizhou. Cao Cao heard that Liu Bei had taken Yizhou and hurriedly sent troops to Hanzhong, which had been the throat of Yizhou since ancient times, and Liu Bei was well aware of the importance of this area, and before he could rest, he rushed to Hanzhong with a large army, and the two men clashed in Hanzhong.
Although Cao Cao was defeated by the Battle of Chibi, his strength was still the strongest prince in the world, and the strong military front and the steady stream of supplies put Liu Bei under great pressure, and the two forces opened a tug-of-war. Later, Liu Bei's military master was highly skilled, and he immediately suggested that Liu Bei send troops after discovering the flaws of the Cao Wei general Xiahou Yuan on the battlefield, so Liu Bei sent the general Huang Zhong to attack and behead Xiahou Yuan on the spot, and finally won the final victory in the Battle of Hanzhong, firmly holding the Hanzhong region in his hands. At this time, cao cao, despite his defeat, forced Emperor Xian of Han to make himself the king of Wei, and Liu Bei thought that he had defeated Cao Cao from the front, and since Cao Cao had already made himself king, he should also be crowned king, so he called himself the king of Hanzhong and then gave his subordinates a knighthood.
Liu Bei's title of king was also the wrong beginning, according to the rules of that era, there must be an emperor's canonization to become king, otherwise even if there is great merit, it will be trespassing. Liu Bei's practice directly announced his ambition to the world, and the mask of "Loyal Servants of the Han Chamber" who had been disguised for decades was torn off, which discouraged many benevolent and righteous people who wanted to turn to him. In addition, he also had great problems with the reward of the Qunchen, he believed that Zhuge Liang had no merit in the Battle of Hanzhong and then did not award it, and then promoted the veteran general Huang Zhong to become a rear general, and then appointed Guan Yu as a former general, but this practice also made Guan Yu angry.
The world knows that Guan Yu was Liu Bei's righteous brother and the third most important person in Shu Han, and now he still commands the whole territory of Jingzhou. Huang Zhong was a general for Guan Yu, neither ability nor seniority was enough to sit on an equal footing with him, so Guan Yu angrily rejected Liu Bei's proposal, and later led the Northern Expedition in order to prove his ability. Guan Yu did win some military achievements in the early days of the Northern Expedition, but because of the emptiness of Jingzhou's defense, eastern Wu took advantage of the void, which eventually led to the defeat and death of his own soldiers, and Jingzhou, which was very important to Shu Han, was also divided between Cao Cao and Sun Quan's families. Although Liu Bei later wanted to launch a war to take back Jingzhou, but at this time, the Shu Han was very different from Cao Wei and Eastern Wu in terms of size and resources, and the results of the war were self-evident, and the defeat at the Battle of Yiling directly laid the foundation for the destruction of Shu Han.
Conclusion: If Liu Bei could understand Zhu Yuanzhang's concept of "building a high wall and slowly becoming a king" in the late Yuan Dynasty, and after the victory in the Battle of Hanzhong, he could cultivate and recuperate and digest this battle result with peace of mind, then perhaps according to Zhuge Liang's strategic plan, there may be a possibility of overturning, but unfortunately Liu Bei drifted after winning the battle against Cao Cao.
