External reasons in different periods, capital in hand. In the history of our country, Liu Bang was the first person to start a business at the grassroots level and finally achieved some emperors' hegemony. The Han Dynasty, which he established after the Qin Dynasty, lasted for more than 400 years, which is a historical miracle. This year, Liu Bang started his army, but his strength was not strong, and he was suppressed by governors headed by Xiang Yu everywhere. But after Liu Bang got Hanzhong, he destroyed Xiang Yu and founded the Han Dynasty.
As a famous historical figure in the Three Kingdoms period, Liu Bei put forward the famous "Longzhong Dui" when he was an official, which clearly saw the changes in the world situation and arranged specific steps and methods. Even in times of crisis, there are corresponding choices, which can be said to be seamless and become the blueprint for Liu Bei's success.
In fact, Liu Bei failed to achieve Liu Bang's great achievements, not because his personal ability was inferior to Liu Bang's, but because the world situation was different at that time. According to the plan of Liu Bei and Zhuge Liang, the unification of the world can basically be divided into two stages: Jingzhou and Yizhou, Guanzhong, Guanzhong area and Guanzhong area.
We should not only have political consciousness, but also recruit soldiers and horses, and at the same time better cooperate with Southeast Sun Quan Group. In the future, if there is an opportunity, we can immediately divide our troops into the northern expedition, attack Qinchuan area from Sichuan along the way, and attack Jingzhou and Wanluo area along the way. Later, Liu Bei did get Jingzhou and Yizhou in this way, and even defeated Cao Cao and got Hanzhong. All this seems to be going well.
When Liu Bang was enfeoffed, Xiang Yu made him the king of Hanzhong for the need of public opinion, in charge of Bashu and Hanzhong areas. However, compared with Bashu in Liu Bei's time, Bashu was completely poor at that time, because the environment there was so bad that many Bashu people fled.
Environmental changes. Bashu area in the Three Kingdoms period was much better than that in Qin and Han dynasties, especially in the plain area, which reached a peak. It is not too much to describe it as rich in products. At the same time, Zhuge Liang himself is also very good at governing the country, which makes the Shuhan regime, which has been fighting for a long time, get sufficient food supply. At that time, the fighting capacity of the Shu-Han army far exceeded that of Liu Bang's Han army.
But the strategic situation that Liu Bang faced at that time was more favorable. Xiang Yu, the main enemy, did not pay attention to himself. In order to stifle Liu Bang's going through the customs, Xiang Yu enfeoffed three vassal states around his fief, but they were all weak and their fighting capacity was no match for Liu Bang at all. Liu bang knows this well. After the establishment of Shu-Han regime, great changes have taken place in the world, even different from the pattern of hegemony and mutual separatism in the late Eastern Han Dynasty. The biggest enemy of Shu Han is Cao Wei, which owns several territories in Guanlong and kanto region.
Cao Wei is a completely independent regime with strong fighting capacity, far less than Xiang Yu. Although Shu Han made bad friends with Dongwu, Dongwu was too far away to form effective assistance. Even if it can help, it is unknown whether Soochow will try its best, so Liu Bei's foreign strategic position is completely inferior to Liu Bang's.
The internal reason of the two-person era is the difference of troops. Liu Bang actually gained the upper hand in military strength when he captured Guanzhong. The banquet at Hongmen also shows that Liu Bang holds 100,000 military forces in his hand, and he was ordered to resist Liu Bang's three princes in Guanzhong, just like "one army". His men broke up with Xiang Yu as early as the Battle of Julu, and later became princes. Even if you recruit again, you can't compare with Liu Bei's men in number and fighting capacity.
This situation was greatly reversed in the Shu and Han Dynasties. In the early and middle period of the establishment of the Shu-Han regime, it experienced the Battle of Jingzhou and the Battle of Yiling. Both major battles ended in the failure of Shu-Han, which damaged the territory of Shu-Han.
The newly established regime has been hit like this one after another, which is undoubtedly fatal and its national strength has been greatly reduced. It is worth noting that in these two world wars, the elite teachers carefully managed by Liu Bei almost disappeared. Although Zhuge Liang was later rebuilt in the Shu-Han army, the Shu-Han army lacked the necessary backbone, which was vividly demonstrated in many northern expeditions.
Before Xiang Yu went through the customs, the world situation was very favorable to him, but he still didn't make a move. The reason is actually very simple. He knew that his biggest opponent was Zhang Han, a famous pre-Qin star, and Xiang Yu's military strength was not his opponent, so he chose to take the initiative to forbear. It was not until Han Xin grew up that Liu Bang realized that he had the right place and the right time, so he decisively sneaked into Chencang and knocked out all his opponents. Therefore, whether Liu Bang or Han Xin, ability is the first.
In the middle and late period, the commanders of Shu Han were mainly Zhuge Liang and others. In the five famous northern expeditions, Shu Han and Cao Wei each won and lost, but they failed to achieve their set goals smoothly. There is not much research on Zhuge Liang's talent and military means by later generations. Although controversial, one thing is certain, that is, Zhuge Liang, as the commander-in-chief of the Shu-Han army, has always been cautious.
This kind of personality is good, but if you March and fight in troubled times, it will become a weakness or even a weakness to a great extent. Cao Wei also realized this, so every time Zhuge Liang mobilized troops, they could roughly calculate Zhuge Liang's plan and deploy it in advance, which increased the difficulty of the success of the northern expedition in Shu and Han Dynasties.
Not only in the romance, but also in the official history, Zhuge Liang's military talents are familiar. He thinks that his best field is governing the country. Therefore, although the conditions of Liu Bei Group seem to be earlier than those of Liu Bang Group in all aspects, the world situation and internal problems are completely different, which also explains why Liu Bang can win the world and Liu Bei has only one side.
