What are the reasons for the development of Jiangnan area in Wei, Jin, Southern and Northern Dynasties?

The main reasons for the development of Jiangnan area are as follows:

1, social unrest in the north and relative stability in the south. This period coincided with the chaos of the Eight Kings in the North, the chaos of China in the Five Dynasties, years of war and social unrest, which was not conducive to the life and survival of the people. During this period, there were relatively few wars in the South and the social order was relatively stable.

2. The population from the north migrated to the south. There are scuffles in the north, and the population dominated by the Han nationality moves south to escape the war. The sudden increase of population in the south of the Yangtze River has brought advanced production tools and technologies.

3. Jinshi moved south, but the political center was difficult to move. The Jin re-established the Eastern Jin Dynasty in Jiankang, and the transfer of political center was very important to the economy.

4. The working people are industrious, reclaiming wasteland and building water conservancy projects, and a large area of wasteland has been reclaimed in Cheng Liangtian.

6. The land in the north is serious. In the northern aristocratic family grange system, the land is relatively concentrated, while the population in the south is small and there are more uncultivated land. In order to meet the demand for land, a large number of new people migrated to the underdeveloped south.

Eight Kings Rebellion?

The Eight Kings Rebellion was a civil strife caused by the royal family's struggle for the central government in the Western Jin Dynasty in China, which was caused by Queen Jia Nanfeng's interference in politics.

The unrest lasted for sixteen years and was divided into two stages: the first stage was from March to June in the first year of Yuankang (29 1), which lasted for three months; The second stage, from the ninth year of Yuankang (299) to the first year of Guangxi (306), lasted seven years.

Its core figures are Sima Liang, King of Ru 'nan, Sima Wei of Chu, Sima Lun, Wang Sima, Changsha, Sima Ying of Chengdu, Sima Yu of Hejian and Sima Yue, the Eight Kings of East China Sea.

The turmoil in the Western Jin Dynasty involved more than eight kings, but eight kings were the main participants, and the Book of Jin merged eight kings into a series of biographies, so the history called this turmoil "the chaos of eight kings."

"Eight Kings Rebellion" is one of the most serious royal civil strife in the history of China. At that time, the social economy was severely damaged, which led to the national subjugation of the Western Jin Dynasty and nearly 300 years of turmoil. Later, China entered the period of five lakes and sixteen countries (five chaos in China).
