Liu Bei Shu Han only enjoyed the country for 42 years, and after that, there were 3 Shu kingdoms tha

Because the geographical location of Shu at that time was very bad, it could not develop.

Mainly because some of the emperors of Shu were very mediocre, such as Wang Yan.

On the one hand, because of the geographical location of Shu, on the other hand, because of the city.

These are all related to the emperor at that time, and he did not handle state affairs well.

After Liu Bei's death, the state of Shu lasted for 40 years, Liu Bei died in 223 AD, and the state of Shu fell in 263 AD.

Liu Bei (161 June 10, 223), the name Xuande, Han nationality, Zhuo County, Zhuo County (now Zhuozhou, Hebei), a descendant of Liu Sheng, King Jing of the Han Dynasty, the founding emperor of Shu Han during the Three Kingdoms period. He was a modest, courteous corporal, lenient to others, ambitious, known and good at making use of people, and was praised by the world for his benevolence, and was a famous politician in the Three Kingdoms period and a famous hero in the Three Kingdoms period. In 221 A.D., he was proclaimed emperor in Chengdu, with the country name Han and the year name Zhangwu, occupying all of present-day Sichuan, most of Yunnan and Guizhou, and part of Hanzhong in Shaanxi and Bailongjiang in Gansu.

Known as Shu or Shu Han in history, he died of illness in the White Emperor City in 223 AD, at the age of 63, he was called Emperor Zhaolie, and the temple was called Liezu, and the historian called him the ancestor again.

Shu Han (May 15, 221 – 263), one of the Three Kingdoms. In 221 AD, Liu Bei was proclaimed emperor in Chengdu, and the country was called Han, known as "Shu" or "Shu Han" in history, also known as "Liu Shu" and "Ji Han". Within the reach of the Shu Han Dynasty, it reached Wudu and Hanzhong in the north, Wuxia in the east, Baoyun and Gui in the south, and eastern Myanmar in the west.

It occupies the whole province of present-day Yunnan, most of Sichuan and Guizhou provinces, Shaanxi, southern Gansu, northwest Guangxi, northeast Myanmar and northwest Vietnam. In 263, it was destroyed by Wei. A total of two emperors, forty-three years.

Three Kingdoms Issue: Zhuge Liang supported Shu for 11 years after Liu Bei's death, and Shu relied on Jiang Wei for 29 years after Zhuge Liang's death.

Zhuge 223-234, then Jiang Wan, then Fei Yi, then the general Jiang Wei, in 263 Wei destroyed Shu.

After Liu Bei's death, Shu supported it for 40 years (223-263).

Liu Bei died in 223, and Shu was destroyed by Wei in 263 AD, so it was 40 years.

Looking at the 900,000 people at the time of the founding of the People's Republic of China, and the 940,000 people when he destroyed the country, it was not only an increase of 40,000, but the annual war and hard work, natural disasters, death, rent, and the interaction of newborns, etc., finally 40,000.

The actual increase in population is much larger than this figure, but the Shu Han Northern Expedition for many years, the war lost a large number of people, so the population only increased by 40,000 in 42 years.

No, because a large number of people fled at that time, or they were attached to the name of the gentry, so these people were not counted in the real mountain dialect population.

Jiang Wan and others' talents are not only manifested in internal politics, but also have great insights into the adjustment of grain and grass. Zhuge Liang returned triumphantly after pacifying the southern dao, and hundreds of civil and military officials went out of the city for dozens of miles to greet him. Fei Yi was just a Lang official by the emperor's side at that time, and there were many ** with a higher rank than him.

But Zhuge Liang specially asked Fei Yi to sit in the same car with him. Since then, everyone has been impressed by Fei Yi.

Of course, Zhuge Liang made two contributions to the subsequent development of Shu at that time.

The talents of Jiang Wan and others are not only manifested in internal affairs, but also have great insights into grain and grass scheduling.

Liu Bei is to reuse Jiang Wan, Fei Yi, Dong Yun and others.

It was Zhuge Liang, and after Zhuge Liang's death, the Shu Kingdom gradually went to the road of destruction.

Of course, it is Zhuge Liang and Zhao Yun, these two will not perish.

The first thing is to reuse Jiang Wan, Fei Yi, Dong Yun and others.

I think this is inseparable from the different historical conditions, geographical conditions, and actual conditions at that time. Let's talk about Liu Bei's Shu land first, at that time Liu Bei occupied Jingzhou, in the east of Liu Bei was Sun Quan's power, and in the north of Liu Bei there was Cao Cao, at that time Liu Bei's power was still very small, only by taking Shu land, this way can expand his power and compete with Sun Quan Cao Cao.

At that time, Liu Bei entered Shu because he was invited, so that Liu Bei could defend Zhang Lu in Hanzhong in the north. At that time, the military Pang Tong and others persuaded Liu Bei to directly take the capital and take Shu. But Liu Bei refused, because Liu Bei understood that this was not a military issue at the beginning, but a matter of people's hearts.

In the seventeenth year of Jian'an, Pang Tong offered Liu Bei three strategies, and the best strategy was to attack Chengdu, but Liu Bei still vetoed him, the reason was that he did not win enough people's hearts in Shu.

But at that time, if from a geographical point of view, if Liu Bei led his troops from Jingzhou into Shu, he could only go by water, because from the Yangtze River to the west by boat, this road was the most convenient route to enter Shu. But Liu Bei just entered Shu and still didn't want to make a big move, and wanted to use favors to ** this land. Later, when Liu Bei began to do it, he also found that in fact, Shu was not easy to conquer.

Moreover, during the first attack, Liu Bei's soldiers did not bring enough, and Zhang Fei was captured, which undoubtedly slowed down the speed of obtaining Shudi. And when Deng Ai attacked Shudi, there was actually another person who was mainly credited, that is, the 100,000 Wei army led by Zhong Hui. At that time, Deng Ai and Zhong Hui attacked Hanzhong and Yuzhong respectively, and because of the incompetence of Liu Houzhu at that time, he was frightened and surrendered, if he insisted at that time, it was actually impossible to defeat Shu quickly with Jiang Wei's ability.

Because Liu Bei entered Shu at that time to help Liu Zhang pacify Ma Chao, he spent a lot of time dealing with Ma Chao. And Deng Ai avoided Jiang Wei with the help of a surprise attack, so he quickly destroyed the Shu Kingdom.

Liu Bei has been calculating, calculating the enemy and calculating his subordinates, various forces fought among themselves, consuming part of their troops, and the terrain in Shuzhong was also steep, making it difficult to let a large number of troops enter at once.

The times are different, Liu Bei's occupation of Shu was due to strategic considerations, and at the same time, it was also forced by the form at that time, while Deng Ai was for the unification of the world.

The times were different, Liu Bei was facing a strong enemy like Cao Cao at that time, but Deng Ai was facing Adou who couldn't be supported.

Geographical conditions limited Liu Bei's journey to Shu at that time, and because of Cao Cao and others at that time, it was not easy for Liu Bei to enter Shu.

The length of time for the two to take Shu is inseparable from their respective historical and geographical conditions at that time.

Because Liu Bei entered Shu from scratch, it was difficult to enter Shu before, and Cao Cao's pursuers were eyeing the enemy.

The different historical conditions and geographical conditions at that time naturally led to the different times when they took Shu.

Although it was only 50,000 people, they were all elite troops, and at the same time lost a base area. also because Zhang Fei was killed, Ma Chao, Huang Zhong and others died one after another, which made the army's morale unstable and greatly reduced.

The main reason is that Liu Bei's 50,000 people lost in the Battle of Yiling were the elite troops of Shu Han, so Shu Han would go downhill.

After the Battle of Yiling, many of the famous generals of Shu Han died, which was one of the reasons for the decline of Shu Han.

It is said that 50,000 people are all elite soldiers, and if they die so many at once, their morale will definitely be seriously damaged, and the people's hearts will be in chaos, causing the Shu Han Society to go downhill.

The 50,000 horses and horses lost by Liu Bei in the Battle of Yiling were all his elite, and after that, the Shu Han talents withered and finally went downhill
