The Sherman Antitrust Act July 2 1890 Poster

The Sherman Antitrust Act (Sherman Act, July 2, 1890, ch. 647, 26 Stat. 209, 15 U.S.C. §§ 1–7) is a landmark federal statute on United States competition law passed by Congress in 1890. It prohibits certain business activities that federal government regulators deem to be anticompetitive, and requires the federal government to investigate and pursue trusts, companies, and organisations suspected of being in violation. It was the first federal statute to limit cartels and monopolies, and today still forms the basis for most antitrust litigation by the United States federal government. However, for the most part, politicians were unwilling to refer to and enforce this law until Theodore Roosevelt's Presidency (1901–1909) and beyond.
