The Clayton Antitrust Act was enacted in 1914 to add additional substance to U.S. antitrust law by seeking to prevent certain anti-competitive practices during their inception, and continued a regime that started with the Sherman Antitrust Act of 1890. The Clayton Act specified particular prohibited conduct, outlined specific exemptions to the law, and provided for a tri-level enforcement regimen including measure intended to remediate prohibited conduct, expanding on the consumer protections that were provided under the earlier enacted Sherman Antitrust Act.
