The Commerce Commission was established on July 4, 1937 when the name of the Board of Railroad Commissioners was changed to the State Commerce Commission. In July 1975, the regulation of railroads and motor carriers was transferred from Commerce to the newly created Department of Transportation. Since 1975 the primary function of the records in RG20 Commerce has been the regulation of public utilities. Records pertaining to railroad and motor transport, regardless of the creating agency, are included in RG 105 Railroad Commissioners/Transportation Regulation. In 1986 several existing departments including Beer and Liquor Control, Banking and Insurance were transferred to the Commerce Commission, for their records refer to RG 12 Alcoholic Beverage Control, RG 10 Banking and RG 53 Insurance. The following is a partial list of holdings.
Some or all of these records are available to search in the Iowa History Collections Catalog
