Ashland was founded in 1924 as Ashland Refining Company of Ashland, Kentucky by Paul G. Blazer. The refinery was originally set up under the guise of the Swiss Oil Company located in Lexington, Kentucky. In 1930, the nearby Tri-State Refining Company was purchased, adding 5,500 barrels per day of capacity to the company. The company continued to merge or acquire other oil companies, combining with Swiss Oil in 1936, Allied Oil in 1948, Aetna Oil in 1949, and purchasing Frontier Oil Refining and National Refining in 1950. By that time, the company began to diversify, adding petrochemicals to its portfolio with the acquisition of R. J. Brown Company in 1956 and United Carbon in 1963.
Diversification continued with the purchase of Warren Brothers in 1966, which later became Ashland Paving and Construction. A significant acquisition was made in 1967 when the company purchased ADM Chemical Group; whose chemical distribution business would go on to be one of the primary businesses of the company in the later part of the 20th century. In 1969, the company reorganized to form Ashland Petroleum, as well as entering into a joint venture in Coal Mining under the name Arch Mineral.
In the 1980's and early part of the 1990's, Ashland continued to expand, buying The Permian Corporation and merging with Scurlock Oil Company in 1991. In 1992, most of Unocal's chemical distribution business was acquired, making Ashland the top chemical distributer in North America. At this time, the Industrial Chemicals & Solvents (IC&S) division was established. The company's name was changed to the present "Ashland Inc." in 1995, which noted the reduced important of oil in the overall business.
The late 1990's saw considerable change in the structure of the company. In 1998, the petroleum division merged with Marathon Oil（马拉松石油） to form Marathon Ashland Petroleum, LLC (MAP). Following that in 1999, the headquarters were moved from Russell, Kentucky to Covington, Kentucky, although the Russel office is still in operation as of 2007. A monumental change came in 2005, when Ashland sold its shares of the Marathon Ashland Petroleum joint venture, to Marathon Oil, effectively dissolving the remnants of their petroleum division. After the sale, the company was no longer involved in the refining or marketing of fuels. The original oil refinery in Catlettsburg, Kentucky is still in operation today and is owned and operated by Marathon. In 2006, Ashland sold APAC (the paving and construction division) to Oldcastle Materials of Dublin, Ireland.
