Understanding the Mccarran Act / Subversive Activities Control Act of 1950

Definition & Meaning

The McCarran Act, officially known as the Subversive Activities Control Act of 1950, is a federal law in the United States aimed at regulating activities deemed subversive to national security. This law mandated that Communist organizations register with the U.S. Attorney General and established the Subversive Activities Control Board to investigate individuals suspected of promoting totalitarian regimes, including fascism and communism. The Act imposed restrictions on members of these organizations, including limitations on citizenship and travel, and allowed for the denaturalization of citizen-members within five years. Although parts of the Act were later deemed unconstitutional by the U.S. Supreme Court, it remained in effect until its repeal in 1993. The Act is named after Senator Patrick Anthony McCarran, a prominent anti-Communist figure during the Cold War.
