Gao 'an City-History Editor Gao 'an has a long history. As early as the late Neolithic Age, there were human settlements and activities in Gao 'an, more than 4,000 years ago. From 65438 to 0977, Jiangxi Provincial Museum conducted an investigation on the Chen Xia site in Gao 'an, which verified this historical fact for the first time. 1982 During the cultural relics survey, sites such as mines, Fanquan, Xiaoshuidong, Zhang Hu, northern Shaanxi and Yan Jiashan were discovered in Xiangcheng area, which was slightly later than Chenxia site, equivalent to the Bronze Age, that is, from the Western Zhou Dynasty to the Spring and Autumn Period.
Xia, Shang and Zhou belong to "Yangzhou territory", and Wu Yuechu and Qin belong to Jiujiang County in the Spring and Autumn Period and the Warring States Period. Gaoanjian County was built in the sixth year of Emperor Gaozu (20 BC1). The jurisdiction of Chengjian County is equivalent to the whole county (city) of Gao 'an, Shanggao, Yifeng and Wanzai and a part of Zhangshu City.
In the fourth year of the Western Han Dynasty (AD 4), the county was re-established as a multi-family county. The old name was restored in the first year of Jianwu in the Eastern Han Dynasty (25 years); During the Zhong Ping period (184 ~ 189), part of Chengjian County was located in Shangcai County (now shanggao county). At the end of the Eastern Han Dynasty, the Three Kingdoms established Sun Wujun. During the reign of Huang Wu (222 ~ 228), part of Chengjian County and Shangcai County were set aside, and Yifeng County and Yang Le County (now Wanzai County) were established.
During the Southern Jin Dynasty, Chengjian County still belonged to Zhang Yu County. In the ninth year (589), the Sui Dynasty unified the whole country, abandoned Wang Cai (that is, Shangcai), enjoyed recreation (that is, Yang Le), and re-established Yifeng. When Zhang Yu County was changed to Hongzhou, it belonged to Hongzhou; In the early years of Daye (605), the abandoned state was restored to the county, and Jianxian County still belonged to Zhangyu County.
The Tang Dynasty changed the county into a state. In the fifth year of Wude (622), in order to avoid the anonymity of Prince Li, it was rebuilt as Gao 'an. According to Taiping Universe, "the earth looks like a high and safe place, hence the name". At the same time, in Gaozhou, Jingzhou, Restoring, Yifeng and Four Counties, Huayang County was added, which was unified with Gaoan five counties in Zhou. In the seventh year of Wude (624), it was renamed Mizhou first, and then Yunzhou; In the eighth year of Wude (625), Jingzhou was abandoned, and Wang Cai, Yifeng, Yang Le and Huayang were merged into Gao 'an County, belonging to Hongzhou.
During the Five Dynasties and Ten Kingdoms period, Gao 'an was first under the jurisdiction of Wu regime and then under the jurisdiction of Nantang regime. In the tenth year of Baoda University (925), Yunzhou was restored, leading Gao 'an, Shanggao, Wanzai and Qingjiang counties, and Gao 'an was Yunzhou's capital.
In the sixth year of the Northern Song Dynasty (98 1), a part of Gao 'an and Shanggao was set aside to establish Xinchang County (now Yifeng County). In the 13th year of Shaoxing (1 143), Yunzhou was renamed Gao 'an County, and Yunzhou was renamed five years later. In the first year of Baoqing (1225), because the word "cloud" was homophonic with the name of Li Zong and Zhao Yun, and it coincided with the discovery of a 14-stem Ganoderma lucidum in the mountain Biluotang behind the national government, which was regarded as an auspicious omen, so Yunzhou was changed to Ruizhou, and Gao 'an was still the county name and was under the jurisdiction of Ruizhou. The Yuan Dynasty changed the state to Tao, and Gao 'an was ruled by Ruizhou Road. In the Ming and Qing Dynasties, the official road was changed, and Gao 'an was ruled by the Swiss government.
In the third year of the Republic of China (19 14), the whole province was divided into four roads, and Gao 'an belonged to Luling Road. 15 (1926) The abandoned road is directly under the control of Gao 'an Province. In 2 1 (1932), the whole province was divided into thirteen administrative regions, and Gao 'an was subordinate to the first administrative region. In the 24th year of the Republic of China (1935), the whole province was reduced to eight administrative regions, and Gao 'an was subordinate to the second administrative region. In the 28th year of the Republic of China (1939), the whole province expanded to eleven administrative regions, and Gao 'an remained the second administrative region. In March1(1942), the whole province was reorganized into nine administrative regions, and Gao 'an was changed into the first administrative region.
July 1949, Gao 'an was liberated. In July 14 of the same year, Gao 'an County People's Government was established, which was under the supervision of the nanchang district Office of Jiangxi Provincial People's Government. 1959 1 Nanchang Commissioner's Office was renamed Yichun Commissioner's Office, and Gao 'an County was under the jurisdiction of Yichun Commissioner's Office. Since then, the Yichun Commissioner's Office has been changed to the Yichun Regional Revolutionary Committee in February, 1968, and the Yichun Regional Administrative Office in July, 1978, and Gao 'an County is still under its jurisdiction. 1April 6, 984, Ligang Town was abolished and Bajing Town was established, which belonged to the former Bajing Commune and the former Ligang Town Neighborhood Committee (Gan [1984] No.77).
