This thesis investigates the political career of Stephen Dorsey, an Ohio industrialist who moved to Arkansas in 1871. Dorsey was elected to the U.S. Senate from Arkansas in 1873, served as secretary of the Republican National Committee for. the election of 1880, and was tried twice, in 1882 and 1883, for the Star Route postal frauds. Although Dorsey was acquitted, the Star Route frauds ended his political career. Separate chapters treat each phase of Dorsey's career. Major sources included the D41 Arkansas Gazette, the Congressional Record, the Garfield Papers, and the official transcripts of the Star Route trials. The thesis concludes that Dorsey's career was, the product of Ulysses S. Grant's influence within the Republican party in. the Gilded Age.
