In the 1790s, the United States faced a series of crises—both domestic and foreign—which many believed threatened the nation’s very existence. These culminated in the Quasi-War with France beginning in 1796. The Federalist majority identified the greatest threats to the Republic as foreigners and their willing or unwitting American allies. Thus, they enacted the Alien and Sedition Acts in 1798 and other laws to allay these threats. Throughout the ensuing debates, Federalists emphasized the dangers of foreign nations who sought to separate the American people from their government. Republicans challenged Federalists’ fears as overblown and defined the real threat as the Federalists themselves who justified the expansion of the general government’s power and the infringement of individual rights in the name of national security. Americans engaged in their first debate about the meaning and limits of liberty and security.
