In history, most of the dynasties died of weakness, but only the Han Dynasty perished because it was too strong, so there was a situation in which the masses competed for hegemony and chased the deer in the Central Plains, and during this period, the situation of the Three Kingdoms was formed, which drew a satisfactory end to the end of the Eastern Han Dynasty. I believe that many friends who have watched the Romance of the Three Kingdoms like the Shu Kingdom, after all, the Shu Kingdom not only has Liu Guanzhang's touching brotherhood, but also many popular stories, which make people fascinated by the customs of the Shu Kingdom, but the most regrettable thing is that the Shu Kingdom was not able to seize the world in the end.

In fact, although the State of Shu was entrenched in Shuzhong and successfully became one of the three legs by virtue of its rugged terrain, its strength was not enough to complete the great cause of unifying the world, which can be seen from the fact that Zhuge Liang's apostles failed to achieve results in the fifteen expeditions before and after, especially during the First Northern Expedition, the State of Shu was actually seriously injured. Next, let's take a look at Zhuge Liang's first Northern Expedition, who were the 11 generals who died, and we will know how badly he lost.
Friends familiar with the Three Kingdoms know that the State of Wei in the Three Kingdoms was dominated by Cao Cao, although Cao Cao's name of this adulterous male was widely circulated, but his desire for talent was also well known, so in the Three Kingdoms period, the strength of the State of Wei was the strongest among the Three Kingdoms.
In order to be able to resist or even defeat the State of Wei, the State of Shu and Eastern Wu began to join forces to resist the enemy, and in the process of joining forces, the State of Wei was defeated and retreated. Therefore, Zhuge Liang also had the idea of the Northern Expedition, wanting to take this opportunity to expand the power of the Shu State, and this time was indeed the most chance of the Shu State.
During the Northern Expedition, the troops led by Zhuge Liang won successive victories, but because of Ma Chen's dereliction of duty, the street pavilion was lost, and the grain route of the Shu Han army was also cut off. As the saying goes, the three armies did not move the grain and grass first, and even the grain road was cut off at this time, so how could they continue to fight? Therefore, the Shu Han army had only the option to withdraw.
After receiving the news, the Wei army, which had previously been suppressed, naturally began to pursue the Shu Han army, causing heavy losses to the Shu Han army that had lost the supply of grain and grass, resulting in the death of many generals, so in the end Zhuge Liang had to tearfully cut off the horse.
This time, although the Northern Expedition achieved a certain advantage in the early stage, but in the end it was defeated miserably because of the failure of the street pavilion, in the process, the Shu Han clique lost the generals Yang Qun, Ma Yu, Yan Zhi, Ding Li, Bai Shou, Liu Gao, and Deng Tong before the battle, and after the war, they beheaded Ma Chen, Zhang Xiu, and Li Sheng, the generals who led to the defeat of the Shu Han clique.
However, for the Shu Han clique, the biggest blow was Zhao Yun, the only surviving of the Five Tiger Generals, who died of illness in the process of this Northern Expedition, and for a while the Shu army almost lost its main heart, and Zhuge Liang had to choose to cultivate and recuperate for the next year.
Of course, we all know the final outcome of the Shu Han Dynasty, in the more than a dozen conquests before and after, the population of the Shu State was almost empty, so it was finally eliminated by the State of Wei, but the Most Unpopular Eastern Wu in the Romance of the Three Kingdoms persisted longer.
