Why a dynasty has the Eastern Dynasty and the Western Dynasty or Northern Song Dynasty, Southern So

The founding emperor of the latter dynasty was not completely orthodox, but had some relationship with the last emperor of the previous dynasty, but was not the heir designated by the emperor such as the crown prince. Although the name of the country is still the same, it is actually another dynasty, so the descendants add "east" and "west" in front of the country name according to the location of its capital to distinguish it.

It depends on the location of the capital! It's all because only half of the country has changed the capital! It is just easy for posterity to distinguish.

The so-called distinction between East and West, North and South lies in the fact that it is easy to distinguish between them. It is usually determined by the location of the capital, and the division of dynasties between east, west, north and south is different. There are mainly the following types, which are divided by themselves for reference:

First, at that time, it was a complete continuation of the previous dynasty. The country name has not changed, the surname has not changed, and the family tree has not changed. But there was a gap between the two dynasties of the same name. For example, the Eastern and Western Han Dynasty, there is Wang Mang's new dynasty in the middle. Between the north and the south of the Song Dynasty, there was a battle of Jingjing, and the two emperors were captured, which was equivalent to the destruction of the country.

Second, in order to facilitate the distinction between dynasties with the same name in history, the names of the former and the latter, for example, the difference between the Li Tang Dynasty and the Later Tang Dynasty of the Five Dynasties, and the difference between the Qin Empire of the First Emperor and the former Qin of Fu Jian. Such dynasties have a long time gap between them, and they are not the same clan and family.

That's all I have to offer.

The so-called Eastern and Western Dynasties, Southern and Northern Song Dynasties, these names were actually not taken by the ancients themselves at that time, but by later generations.

The purpose is to distinguish different periods of the same dynasty, and the criteria are mainly: 1. Moving the capital 2. Rebellion.

3. The rise and fall of the country.

The reason for this division is that after the previous dynasty was destroyed, a new regime was re-established, and a prefix was added to distinguish it. To put it simply, one country has two 'governance'. Finish beating the soy sauce. Flash.

1.Moved the capital. 2.When a nation is destroyed, it is re-established elsewhere.

Moved the capital for some reason...

It is divided according to the geographical location of the capital.

This stalk is: The Song Dynasty in 457 AD was established by Liu Yu in 420 AD instead of the Eastern Jin Dynasty. In order to distinguish the Northern Song Dynasty established by Zhao Kuangyin and the Southern Song Dynasty established by Zhao Jian, historians refer to the Song Dynasty established by Liu Yu as Liu Song.

During the Southern Dynasties, Liu Song was the strongest dynasty among the four dynasties of the Southern Dynasties, and the Southern Qi, Liang, and Chen of the Southern Dynasties did not reach the strength of the Southern Song Dynasty in terms of territory and national strength.

Southern Song Dynasty, the biggest rival is the Northern Wei Dynasty established by the Tuoba clan of North Korea, the Northern Wei Dynasty in terms of national strength and territory, do not go to the Song Dynasty established by Liu Yu, but unfortunately the Song Dynasty has such a strong national strength, but in the end there was a faint monarch in the later period, and was finally replaced by Xiao Daocheng's Qi Dynasty.

Introduction to the Southern Song Dynasty:

The Southern Song Dynasty (420-479), the first dynasty of the Southern Dynasties of the Northern and Southern Dynasties of China, is also the dynasty with the longest existence, the largest territory and the strongest national strength among the four dynasties of the Southern Dynasties. A total of four generations, after nine emperors, 60 years of enjoyment. Because the monarch's surname is Liu, in order to distinguish it from the Song Dynasty established by Zhao Kuangyin, it is also called Liu Song; According to the end of the five virtues, it is the water virtue, so it is also called the water song.

Liu Yu took advantage of the turbulent times at the end of the Eastern Jin Dynasty to rise up, and successively pacified Sun En, Huan Xuan, Liu Yi, Lu Xun, Sima Xiuzhi and other forces, and destroyed Huan Chu, Western Shu, Southern Yan, Later Qin and other countries. It not only unified southern China, but also recovered Shandong, Henan, and Guanzhong, and finally built the Song Dynasty on behalf of the Jin Dynasty, with the capital of Jiankang (now Nanjing, Jiangsu) and Zhongjing (now Luoyang, Henan) as the accompanying capital.

Because at that time, the northern Jin Kingdom came over and occupied one-third of the territory of the Song Dynasty at once. At that time, the Song Dynasty could not defeat the Jin State at all, so it moved its capital to the south, that is, to retreat, so it was called the Southern Song Dynasty.

During this period, there was also a dynasty in the mold that was Zhang Bangchang's pseudo-"Great Chu" regime, but guess that because this dynasty only existed for a few dozen days, there was no record.

Great Chu existed for a very short time, only 33 days, and under the Juche view of history, Zhang Bangchang's pseudo-Chu emperor identity was generally not recognized.

The Great Chu regime lasted for a very short period of time, only 33 days, so it was ignored by the people.

<>1. The reason why the Song Dynasty was divided into north and south was because of the relocation of the capital and the change of the territory caused by the fate of the major events.

2. The Song Dynasty itself is not divided into the Northern and Southern Song Dynasty, but the previous Song Dynasty was destroyed by the Jin Dynasty and dug the core Zheng, and the royal relatives of the original Song Dynasty ascended the throne in Hangzhou, divided the river and ruled, and declared that it would continue to be the regime of the Song Dynasty, because south of the Yangtze River, the history is called the Southern Song Dynasty, and the original Song Dynasty that was destroyed is called the Northern Song Dynasty.

1. The dynasties after the Northern Song Dynasty and between the Southern Song Dynasty are called "Pseudo-Chu".

2. Pseudo-Chu, the country name is "Da Chu", "Chu", also known as "Zhang Chu", "Jingkang's Shame", Jin Bing supported the puppet regime established by Zhang Bangchang, the former Dazai of the Northern Song Dynasty, and the country name was "Da Chu", "Chu", and later generations also called "Zhang Chu". From March 7 to April 10, 1127, due to the opposition of the Northern Song Dynasty military and civilians, it only existed for a short month.

3. At the end of the Northern Song Dynasty, the Jin army invaded southward, quickly broke through Bianjing, captured Huiqin Erzong, and occupied a large area of land in the northern Northern Song Dynasty, but because the Jin State was still in the late stage of the slave society, it could not rule the Northern Song Dynasty land that was already at the peak of feudal society, and at the same time, in order to avoid being directly hit by the uprising of the remnants of the Song Dynasty in the north, the Jin State ruled by supporting some puppet regimes in these areas, and the puppet Chu regime was one of them.

4. Although the puppet Chu regime existed for a short time, its appearance was an important event in the alternation of the two Song Dynasty.
