The Anti-Monopoly Party was a progressive political party in the United States which was active from 1876 to 1886. The party was founded by former congressman Ignatius L. Donnelly, and it advocated for the direct election of US Senators, a graduated income tax, industrial arbitration, the establishment of labor bureaus, support for workers' rights, antitrust legislation, low tariffs, and an end to land grants for railroads and other corporations. The party ran Benjamin F. Butler as its presidential nominee in 1884, but his defeat led to the Anti-Monopoly Party falling apart outside of Kansas, which continued to run local candidates until 1886. The Anti-Monopoly Party was succeeded by the Populist Party.
