Source-derived summary

The Alien Registration Act, popularly known as the Smith Act, 76th United States Congress, 3rd session, ch. 439, 54 Stat. 670, 18 U.S.C. § 2385 is a United States federal statute that was enacted on June 28, 1940. It set criminal penalties for advocating the overthrow of the U.S. government by force or violence, and required all foreigners over the age of 14 to register with the federal government.

Approximately 215 people were indicted under the legislation, including alleged communists and socialists. Prosecutions under the Smith Act continued until a series of U.S. Supreme Court decisions in 1957 reversed a number of convictions under the Act as being unconstitutional. The law has been amended several times.

Legislative history

The U.S. government has attempted on several occasions to regulate speech in wartime, beginning with the Alien and Sedition Acts of 1798. During and following World War I, a series of statutes addressed a complex of concerns that included enemy espionage and disruption, anti-war activism, and the radical ideologies of anarchism and Bolshevism, all identified with immigrant communities. Congressional investigations of 'extremist' organizations in 1935 resulted in calls for the renewal of those statutes.

Editorial analysis

Why this record matters

The phrase “united States federal statute” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
