Alien and Sedition Acts (1798): Free Speech in the Early Republic
The Alien and Sedition Acts were four laws passed by a Federalist Congress in 1798 during the Quasi-War with France. Their terms, prosecutions and legacy.

The Alien and Sedition Acts were four laws passed by the United States Congress in June and July 1798, during an undeclared naval war with France. Pushed through by the Federalist Party and signed by President John Adams, they restricted immigrants and made it a crime to publish false and malicious criticism of the federal government. Used chiefly against opposition newspapers, they provoked a fierce debate over free speech and states’ rights and contributed to the Federalists’ defeat in 1800.
Background: the Quasi-War with France
By the late 1790s American politics was sharply divided between the Federalists, led by figures such as Adams and Alexander Hamilton, and the Democratic-Republicans of Thomas Jefferson and James Madison. Federalists generally favoured Britain and a strong central government; Republicans sympathised with revolutionary France and feared concentrated power.
Relations with France collapsed after the 1795 Jay Treaty with Britain. French warships and privateers seized hundreds of American merchant ships. In 1797 Adams sent envoys to Paris, but agents of the French foreign minister Talleyrand, referred to in the published dispatches as X, Y and Z, demanded a bribe and a loan before talks could begin. When the XYZ Affair became public in April 1798, it caused a wave of anti-French feeling.
Congress expanded the navy and the army, and fighting at sea, known as the Quasi-War, lasted from 1798 to 1800. Many Federalists believed that French agents and radical immigrants, especially from Ireland and France, threatened the country from within. They were also angered by Republican newspapers that attacked Adams in harsh and often personal terms. Federalists had already blamed Republican political clubs for stirring up the Whiskey Rebellion of 1794, and many now regarded organised opposition itself as disloyal.
The four laws
The Naturalization Act of 18 June 1798 raised the period of residence needed to become a citizen from five to fourteen years. Since most immigrants who became citizens tended to vote Republican, critics saw the act as partisan.
The Alien Friends Act of 25 June 1798 allowed the president to order the deportation of any non-citizen he judged dangerous to the peace and safety of the United States, without a trial. It was limited to two years. Adams never formally used it to deport anyone, though several foreigners left the country in fear of it.
The Alien Enemies Act of 6 July 1798 allowed the president, in time of declared war or invasion, to arrest, restrict or remove nationals of an enemy country. Because war with France was never declared, it was not used at the time.
The Sedition Act of 14 July 1798 made it a crime to conspire to oppose federal measures and to write, print or utter “false, scandalous and malicious” statements against the government, either house of Congress or the president, with intent to bring them into contempt. Penalties for publication reached a fine of up to 2,000 dollars and two years in prison. Unlike earlier English law, it allowed truth as a defence and let juries decide whether a statement was libellous. Notably, it did not protect the vice-president, who was then Jefferson, and it was set to expire on 3 March 1801, the day before the next presidential term began.
Prosecutions
Federal officials enforced the Sedition Act energetically, mostly against Republicans. Historians count roughly two dozen arrests or indictments under the act, with around ten convictions, along with several cases brought under federal common law.
The first person convicted was Matthew Lyon, a Republican congressman from Vermont, who had already gained notoriety for a fight on the House floor with the Federalist Roger Griswold in early 1798. In October 1798 Lyon was sentenced to four months in prison and a 1,000-dollar fine for writings accusing Adams of an unbounded thirst for ridiculous pomp. Voters re-elected him while he was in jail.
Benjamin Franklin Bache, grandson of Benjamin Franklin and editor of the Philadelphia Aurora, the leading Republican paper, was arrested in June 1798 under common law, but he died of yellow fever in September before he could be tried. His successor, William Duane, was also prosecuted. Thomas Cooper, a scientist and writer, received six months in prison, and James Thomson Callender was sentenced in 1800 to nine months for a pamphlet attacking Adams. In Massachusetts, David Brown received eighteen months, the longest sentence, after helping to erect a liberty pole with a slogan denouncing the government.
The Kentucky and Virginia Resolutions
Republicans argued that the Sedition Act violated the First Amendment of the Bill of Rights, which forbids Congress to abridge freedom of speech or of the press. Since the federal courts were staffed by Federalist judges who upheld the act, Jefferson and Madison turned to the state legislatures.
Jefferson secretly drafted resolutions adopted by Kentucky in November 1798, and Madison wrote resolutions adopted by Virginia in December. Both declared the Acts unconstitutional and argued that the Constitution was a compact among the states, which had the right to judge when the federal government exceeded its powers. Jefferson’s original draft even spoke of nullification, the idea that a state could declare a federal law void.
No other state endorsed the resolutions, and several northern legislatures rejected them. Madison defended Virginia’s position in his Report of 1800. The compact theory they set out was later invoked, against the authors’ intentions in some cases, by supporters of nullification and secession in the nineteenth century.
Repeal and political fallout
The Acts became a central issue in the election of 1800. Republicans portrayed the Federalists as enemies of liberty, while Adams’s own decision in 1799 to send a new peace mission to France split his party. Jefferson won the presidency and Republicans took control of Congress.
The Sedition Act expired on 3 March 1801, and the Alien Friends Act had already lapsed in 1800. Jefferson pardoned those still serving sentences under the Sedition Act, and in 1802 Congress restored the five-year residence requirement for naturalisation. Decades later, in 1840, Congress repaid Matthew Lyon’s fine, with interest, to his heirs.
Legacy
The Sedition Act was never reviewed by the Supreme Court, but it has been widely condemned. In New York Times Co. v. Sullivan (1964), the Court observed that, although the act had never been tested there, the attack on its validity had carried the day in the court of history. Its prosecutions are often cited as an early warning about restricting dissent in times of crisis.
The Alien Enemies Act remains part of American law. It was invoked during the War of 1812 and, more widely, during both world wars to detain or restrict German, Italian and Japanese nationals.

Why it matters
The Alien and Sedition Acts were the first major test of the First Amendment and of how far a democratic government may go to silence its critics in wartime. The backlash against them helped shape the American understanding of free speech, and the debate they sparked over states’ rights echoed through American politics for decades.
Frequently asked questions
What were the Alien and Sedition Acts?
They were four laws passed by the Federalist-controlled Congress in June and July 1798: the Naturalization Act, the Alien Friends Act, the Alien Enemies Act and the Sedition Act. Together they made it harder for immigrants to become citizens, allowed the president to deport foreigners, and made it a crime to publish false and malicious criticism of the government.
Why were the Alien and Sedition Acts passed?
The United States was in an undeclared naval war with France, known as the Quasi-War, after the XYZ Affair. Federalists feared French agents and radical immigrants, many of whom supported the opposition Democratic-Republican Party, and resented attacks on President John Adams in Republican newspapers.
Who was prosecuted under the Sedition Act?
About two dozen people were arrested or indicted, mostly Republican editors and politicians, and around ten were convicted. They included Congressman Matthew Lyon of Vermont, the pamphleteer James Thomson Callender and the scientist and writer Thomas Cooper.
What were the Kentucky and Virginia Resolutions?
They were protests against the Acts adopted by the Kentucky and Virginia legislatures in late 1798, secretly drafted by Thomas Jefferson and James Madison. They argued that the laws were unconstitutional and that states could judge when the federal government exceeded its powers.
Is the Alien Enemies Act still in force?
Yes. Unlike the other three laws, which expired or were repealed by 1802, the Alien Enemies Act was never repealed. It allows the government to detain or deport nationals of an enemy country in wartime and was used during the War of 1812 and both world wars.
