Alien and Sedition Acts — Quick Facts
The Alien and Sedition Acts were a series of four laws passed by the Federalist-controlled Congress in 1798
- The Naturalization Act, passed on June 18, extended the residency period from 5 to 14 years for aliens seeking citizenship; this law was aimed at Irish and French immigrants who were often active in Republican politics.
- The Alien Act, passed on June 25, allowed the expulsion of aliens deemed dangerous during peacetime.
- The Alien Enemies Act, passed on July 6, allowed the expulsion or imprisonment of aliens deemed dangerous during wartime. This was never enforced, but it did prompt numerous Frenchmen to return to France.
- The Sedition Act, passed on July 16, provided for fines or imprisonment for individuals who criticized the government, Congress, or president in speech or print.
