The Clayton Antitrust Act: APUSH Topics to Study for Test Day

The Clayton Antitrust Act was part of the early 20th-century efforts to curb the power of big businesses. Clayton Antitrust Act APUSH questions focus on the reasons for and impact of this key legislation.

What is the Clayton Antitrust Act?

In the late 1800s and early 1900s, industrial giants grew in the United States largely unchecked. They engaged in unfair business practices such as monopolies, pools, and price fixing. The Sherman Antitrust Act of 1890 was the first piece of legislation to try to deal with this problem. The law was weak, however, and let corporations avoid prosecution through numerous loopholes. Despite the best efforts of trust-buster Theodore Roosevelt to enforce the law, big businesses continued to grow and hinder healthy competition. That’s where the Clayton Antitrust Act came in.

In 1914, Congress passed the Clayton Antitrust Act. It expanded and strengthened the provisions of the earlier Sherman Act, allowing the government to more effectively restrict harmful business practices. It provided a more precise definition of anti-competitive business practices and gave the government more power to enforce the law. The government could now restrict not only monopolies but also certain mergers, holding companies, exclusive dealing, and price discrimination.
