The development history of Jiangxi can be traced back to the Paleolithic Age more than 10,000 years ago.
There are John (Jiangxi and Guangdong) and Bai Pu in Jiangxi, and the note in Xunzi's Persuasion is "the name of John's ancient country". During the Spring and Autumn Period and the Warring States Period, Wu, Yue and Chu fought for Jiangxi.
Thirty-six counties in Qin Dynasty, Jiujiang County, Jiangxi Province, including Luling County, Xingan County and Nanbu County. Jiangxi, as a clear administrative regional system, began in the early years of Emperor Gaozu. At that time, Zhangyu County (Ganjiang was originally named Zhangyuhe) was established.
County governs Nanchang County and 18 County. They are Nanchang, Luling, Pengze, Poyang, Chaisang, Gan, Xingan, Yichun, Ai, Anping, Haishun, Lilinghe and so on. Their distribution areas are Ganjiang River, Xujiang River, Xinjiang River, Xiushui River and the coast of Shui Yuan, which are roughly the same as those of later Jiangxi provinces.
During the period of Emperor Wu of the Han Dynasty, the whole country was designated as 13 prison area, called 13 county, and Jiangxi belonged to Yangzhou Secretariat Department.
In the fifth year of Jian 'an (200 years), Sun Ce was divided into Luling County and Yudu County. In the 15th year of Jian 'an (2 10), Sun Quan established Pengze County (Imperial concubine of Xuan) and Poyang County. In the fifth year of Jiahe (236), Sun Quan set up a captain in Luling South and moved to Yangzhou.
In the first year of Yuankang in the Western Jin Dynasty (29 1), it was changed to Jiangzhou, and the main body was the original county of Jiangxi. During the Sui Dynasty, the administrative divisions were adjusted, and the level of the state was the same as that of the county, so there were 7 counties and 24 counties in Jiangxi in the Sui Dynasty. In the Tang Dynasty, it increased to 8 states and 37 counties, namely Hongzhou, Raozhou, Qianzhou, Jizhou, Jiangzhou, Yuanzhou, Fuzhou and Xinzhou.
In the first year of Zhenguan of Emperor Taizong (627), the whole country was designated as 10 monitoring area, and Jiangxi belonged to Jiangnan Road. In 733, in the twenty-first year of Emperor Xuanzong of the Tang Dynasty, it was increased to 15 Road, belonging to Jiangnan West Road. Its supervision area governs eight states: Hong, Rao, Qian, Ji, Jiang, Yuan, Fu and Xin, and Hongzhou (Nanchang).
In the Five Dynasties, Jiangxi belonged to Wu first, and then to the Southern Tang Dynasty. During this period, there appeared a new administrative division equivalent to the lower state: 6 states, 4 armies and 55 counties. In the first year of Jiaotai (958), the Southern Tang Dynasty decided to build Nandu in Hongzhou, and therefore promoted Hongzhou to Nanchang Prefecture.
In the Song Dynasty, the roads above the state were diverted, and Jiangnan Road was initially set up. In the fourth year of Tianxi (1020), Jiangnan Road was divided into Jiangnan East Road and Jiangnan West Road. Jiangxi has jurisdiction over 9 States, 4 armies and 68 counties, most of which are under the jurisdiction of Jiangnan West Road and still under the jurisdiction of Hongzhou, and some are under the jurisdiction of Jiangnan East Road.
The Yuan Dynasty established the system of "province in province". The jurisdiction of Jiangxi Province is greater than that of Jiangxi Province. Except for most of today's Jiangxi (formerly northeast Jiangxi belongs to Jiangsu and Zhejiang provinces) and most of today's Guangdong Province.
Jiangxi Province governs Longxing, Ji 'an, Nankang, Ganzhou, Jianchang, Jiangzhou, Nan 'an, Ruizhou, Yuanzhou, Linjiang, Fuzhou, Raozhou, Xinzhou 13 Road, Nanfeng and Buried Hill, as well as 48 counties and 16 county-level states.
