How did Theodore Roosevelt regulate the growth of trusts?

Theodore Roosevelt used the Sherman Antitrust Act to regulate the growth of trusts, viewing them as monopolistic entities that threatened fair competition and consumer protection. His administration actively pursued legal action against major corporations, most notably the Northern Securities Company, which led to a landmark Supreme Court case in 1904. Roosevelt's efforts established the precedent for federal intervention in corporate practices, promoting a more balanced economic environment while earning him the nickname "Trust Buster." His approach emphasized the need for regulation rather than outright dismantling of large corporations, fostering a system of responsible capitalism.
