As early as 4,000 to 10,000 years ago, Lushan has entered the era of farming. In 316 B.C., King Huiwen of Qin established Qingyi County after the Qingyi Qiang State, being the earliest name for the present Lushan County. In the 2nd year of the Yangjia reign in the Eastern Han Dynasty (133 A.D.), it was renamed Hanjia County, meaning to be rewarded by the Han Dynasty. In the Three Kingdoms Period, it was named Yangjia County. In the 3rd year of the Renshou reign in the Sui Dynasty (603 A.D.), it was named Lushan County (盧山縣), later Dadu County from the Tang Dynasty to the Song Dynasty. In the 20th year of the Zhiyuan reign in the Yuan Dynasty (1283 A.D.), it was named Lushan County (瀘山縣). In the 6th year of the Hongwu reign in the Ming Dynasty (1373 A.D.), it was renamed Lushan County (蘆山縣). This name is still in use today.
With a long history of more than 2,300 years, it was governed by Qingyi Prefecture in the Qin Dynasty, Western Military Prefecture in the Han Dynasty and Hanjia Prefecture in the Three Kingdoms Period. From October 1935 to February 1936, the Fourth Front Army of the Chinese Workers’ and Peasants’ Red Army established the provincial and county Soviet regime in Lushan and the CPC Sichuan Provincial Committee and Lushan County Committee. In February 1950, the CPC Lushan County Committee and Lushan County People's Government were established. In history it can be said to be a strategic place.
