From 1790 to 1794 the French Revolution became increasingly radical. After French King Louis XVI was tried and executed on January 21, 1793, war with Great Britain and Spain was inevitable, and the two powers joined Austria and other European powers in the war against Revolutionary France that had already started in 1791. The United States remained neutral, as both Federalists and Democratic-Republicans saw that war would lead to economic disaster and the possibility of invasion. This policy was made difficult by heavy-handed British and French actions. The British harassed neutral American merchant ships, while the French government had dispatched a controversial minister to the United States, Edmond-Charles Genêt, whose violations of the American neutrality policy embroiled the two countries in the Citizen Genêt Affair until his recall in 1794.
Although the French Revolution had ended its radical phase, Federalists in the United States remained wary of revolutionary ideology infiltrating the United States. Many French citizens, refugees from the French and Haitian revolutions, had settled in American cities and remained politically active, setting up newspapers and agitating for their political causes. A French spy, Victor Collot, traveled conspicuously through the United States in 1796, noting the weaknesses in its western border. When a breakdown in diplomatic negotiations resulted in the Quasi-War with France, the Federalist-controlled Congress passed a series of laws known as the Alien and Sedition Acts, intended to curb political dissent and limit the political participation of immigrants by easing deportation and lengthening the time required for citizenship. A number of political radicals were arrested for sedition, including Congressman Matthew Lyon and newspaper editors James Thompson Callendar and William Duane. Many refugees, sensing American hostility, chose to return to France and Haiti, the political situation having temporarily calmed in both places.
However, the Alien and Sedition Acts, originally intended to prevent a growth in pro-French sentiment, actually backfired for the Federalists. Taken aback from such extreme measures, swing voters in the presidential election of 1800 instead backed the pro-French Thomas Jefferson and his Democratic-Republican party, instead of the Federalist John Adams, who was running for re-election as president. Adams himself had alienated the anti-Revolutionary wing of his party by seeking peace with France, whose revolution had already been brought to a close by General Napoleon Bonaparte.
Despite Federalist warnings that electing Jefferson would bring revolution to the United States, this did not happen. Jefferson instead chose to distance himself from political radicals and win over political moderates. The revolution in France was over, and while many Americans voters sympathized with the revolution in the abstract, they did not really want the revolution’s most radical changes put into effect in the United States.
