The most powerful commander during the Three Kingdoms period was definitely Cao Cao, because he was ambitious and decisive in his killing, and ruled the north. In contrast, Liu Bei, as the supreme commander of the Shu Han Dynasty, was somewhat inferior. As we all know, Liu Bei has always been a benevolent and righteous person, so it is difficult to achieve great things. Finally, Liu Bei died in the White Emperor City. Before his death, Liu Bei also called Zhuge Liang to take care of him, and it is reasonable to say that Zhuge Liang was Liu Bei's most trusted person and should also give zhuge liang the military power, but Liu Bei did not do so. So, what is Liu Bei worried about? Before dying, give the military power to Li Yan instead of Zhuge Liang?
At the beginning, after Guan Yu was defeated and killed, Liu Bei, who was bent on revenge, did not heed the persuasion and led the Shu army to launch a major battle against Eastern Wu, known in history as the "Battle of Yiling". This battle not only changed the fate of the Shu kingdom, but also shook the situation in which the three kingdoms were established. Liu Bei did not take Zhuge Liang with him before the expedition, and since he was not a resourceful man, he was burned by Lu Xun after penetrating deep into the hinterland of Eastern Wu and returned with a crushing defeat. Soon, Liu Bei was critically ill in the White Emperor City, and immediately rushed to the orphan. However, he gave the military power to Li Yan, not Zhuge Liang, for three main reasons.
The first is to value Li Yan's talent. At first, Liu Bei and Cao Cao fought endlessly in Hanzhong, while Li Yan sat in the rear. Not long after, Ma Qin and Gao Sheng took the opportunity to lead tens of thousands of people to rebel. Liu Bei, who was busy with combat, had no time to take care of the rebellion, and Li Yan immediately commanded several thousand soldiers and horses to quickly quell the rebellion. It can be seen from this that Li Yan's ability to lead troops is very strong. In comparison, Zhuge Liang's rescue was not as good as Li Yan's. With this in mind, Liu Beicai decided to give the military power to Li Yan instead of Zhuge Liang.
The second is to avoid internal contradictions. At that time, there were several major factions in the Shu Han Dynasty, but after the deaths of Guan Yu, Zhang Fei and others, the Yizhou and Jingzhou factions became the two largest factions. Li Yan belonged to the Yizhou faction, while Zhuge Liang belonged to the Jingzhou faction. At this time, if the political power and military power were to be handed over to Zhuge Liang, it would inevitably cause dissatisfaction among the Yizhou faction, especially those dignitaries and dignitaries in the Yizhou faction. Because of this, Liu Bei did not hand over the military power to Zhuge Liang.
Finally, it is to prevent Zhuge Liang from monopolizing power. Although Liu Bei was a benevolent and righteous prince, he was not a stupid person, and he knew very well that if he entrusted the political power and military power to one person to take care of, it would inevitably have some unexpected and serious consequences. Even if Liu Bei had a lot of trust in Zhuge Liang, Zhuge Liang was only an outsider after all, and he had to take precautions. Therefore, only by handing over the military power to Li Yan could Zhuge Liang not be allowed to monopolize the power.
