The legislation controlling corporation competition practices was called?

The legislation controlling corporate competition practices is primarily embodied in the Sherman Antitrust Act of 1890. This act was designed to prevent monopolistic behaviors and promote fair competition in the marketplace. Additionally, the Clayton Antitrust Act of 1914 and the Federal Trade Commission Act of 1914 further strengthened regulations against anti-competitive practices. Together, these laws form the foundation of antitrust regulation in the United States.
