The Three Kingdoms Period in Chinese history generally refers to the period from 220 to 280 AD. During this period, the Central Plains mainly existed in the three regimes of Cao Wei, Shu Han, and Sun Wu. The battle of Guandu established Cao Cao’s dominance in the north. Sun Quan took over his father and brother’s foundation and defeated Cao Jun in the Battle of the Red Cliff.
During the Eastern Han Dynasty, the territory controlled by the Han Dynasty was divided into thirteen states. Cao Cao started his army from Chen Liu and gradually controlled Luzhou and Hezhou. In Xuzhou, he adopted Mao Zedong’s strategy of”bongtianzi’s order to imperish, cultivate, plant animal husbandry,” and slowly accumulated his strength.
In the first official battle, Cao Cao defeated Yuan Shao, the largest power in the north, and won Ji, Qing, You, and the four states in one fell swoop, becoming the largest vassal force at that time. After nearly 20 years of operation, Cao Yu became the emperor At that time, the thirteen states left by the Eastern Han Dynasty, the Cao Wei regime alone won Kyushu. According to the”General History of China’s Population”, it has a population of about 13 million people and an area of about 4 million square kilometers.
The establishment of Dongwu started from Sun Jian, and after the expansion of Sun Ce and the consolidation of Sun Quan, until Sun Quan declared the emperor to formally establish Wu Kingdom, his The majority of Yangzhou and Jingzhou, which have the 13 states of the Han Dynasty, and the entire territory of Jiaozhou, the territory includes all areas of today’s Zhejiang, Fujian, Jiangxi, Guangdong, and Hunan, and parts of Jiangsu, Guangxi, Anhui, Hubei, Chongqing, Shanghai, Its population is about 5.5 million. Wu Kingdom was also the longest country in the Three Kingdoms Period, enjoyed the country for 52 years, and was finally destroyed by the Western Jin Dynasty.
Compared with Cao Cao ’s founding history, Liu Bei ’s process of establishing Shu Han was a lot more difficult. Before entering Sichuan, there was no fixed basic disk It was not until after entering Sichuan that Yizhou was used as a base. After Liu Bei established Shu Han, his territory has the entire territory of Yunnan today, Sichuan, Guizhou, and scattered borders of Shaanxi, Gansu, Guangxi, Myanmar, and Vietnam.
According to the data, one year before the death of Shu Han, the country was only beneficial to the state, with a population of nearly one million and an area of about 1 million square kilometers. In this way, in the more than forty years since the establishment of Shu Han, the only areas that can be effectively ruled are Chengdu Plain, Chongqing, and parts of Hanzhong. Because its territory partially overlaps with the Wu State, Shu Han’s control of it is not strong.
At the time, the southern part of the country was not like the Jiangnan water village and the country of heaven, but it was spread all over the virgin forest, and the climate was hot. Humid, with radon in many places. Many of the worst areas of Shu Han are such places. In addition, there are many wild mountains in the mountains, and the number of people who can actually start is far lower than in other two countries. The richest and most populous area in the world was occupied by Cao Cao, so when the country was unified, the north unified the south.
Across China’s thousands of years of history, there were only two successful areas of the Northern Expedition, so Zhu Geliang’s Northern Expedition was doomed from the beginning, and Liu Bei’s dream of unifying the world was also a flower in the mirror and a moon in the water.
