The Sherman Antitrust Act was the first act passed 1890 by the U. This act was named after Senator John Sherman. Due to its performance, many different states passed similar laws. These laws in the other states were limited to intrastate businesses. Many different factors led the Congress to pass the Sherman Act. Some of these factors were: 1. Opposition to the concentration of economic power in large corporations 2. Business concerns. The act was based on the constitutional power of the Congress to regulate interstate commerce. The Sherman Act also declared illegal every contract, combination (in the form of trust or otherwise), or conspiracy in restraint of interstate and foreign trade. A fine of $5,000 and imprisonment for one year were set as the maximum penalties for violating the act. The Sherman Act authorized the federal government to institute proceedings against trusts in order to dissolve them, but Supreme Court rulings prevented federal authorities from using the act for some years. As a result of President Theodore Roosevelt's "trust-busting" campaigns, the Sherman Act began to be invoked with some success, and in 1904 the Supreme Court upheld the government in its suit for dissolution of the Northern Securities Company. The act was further employed by President Taft in 1911 against the Standard Oil trust and the American Tobacco Company. In the Wilson administration the Clayton Antitrust Act (1914) was enacted to supplement the Sherman Antitrust Act, and the Federal Trade Commission (FTC) was set up (1914). Antitrust action sharply declined in the 1920s, but under President Franklin Delano Roosevelt new acts supplementary to the Sherman Antitrust Act were passed (e.g., the Robinson-Patman Act), and antitrust action was vigorously resumed. The Hart-Scoss-Rodino Anti-Trust Improvement Act (1976) made it easier for regulators to investigate mergers for antitrust violations, but few mergers were blocked during the merger boom of the 1980s.
