Alien and Sedition Acts

Updated · For the May 2027 AP exam

The Alien and Sedition Acts were four 1798 Federalist laws that lengthened the wait for citizenship, let the president deport noncitizens, and criminalized false and malicious writing about the government.

When
June–July 1798

Definition

During the Quasi-War with France, the Federalist Congress passed four laws in June and July 1798. The Naturalization Act raised the wait for citizenship from five years to fourteen, and two Alien Acts let the president deport noncitizens he judged dangerous and detain enemy nationals in wartime. On July 14, President Adams signed the Sedition Act, which made it a crime to publish false, scandalous and malicious writing against the government, Congress or the president, but not the vice president, Thomas Jefferson. Nearly everyone charged under it was a Democratic-Republican editor, printer or supporter, and Congressman Matthew Lyon of Vermont received a four-month jail sentence and a fine of one thousand dollars, then won re-election while he was still in jail.

Why it matters on the AP exam

Federalists aimed the acts at immigrants, who mostly backed the Republicans, and at Republican critics, who said the Sedition Act violated the First Amendment. The acts are a main example of the 1790s struggle over the balance between liberty and order, and they prompted the Kentucky and Virginia Resolutions, in which Jefferson and Madison argued that the acts were unconstitutional and that the Union was a compact among the states. Questions ask students what the acts were designed to do and how the Republicans responded. The backlash helped Jefferson win the election of 1800; the Sedition Act expired in 1801, Jefferson pardoned people convicted under it, and Congress restored the five-year wait for citizenship in 1802.
