Why did the French Revolution affect American politics?

The French Revolution lasted from 1789 until 1799. The Revolution precipitated a series of European wars, forcing the United States to articulate a clear policy of neutrality in order to avoid being embroiled in these European conflicts. The French Revolution also influenced U.S. politics, as pro- and anti- Revolutionary factions sought to influence American domestic and foreign policy.

When the first rumors of political change in France reached American shores in 1789, the U.S. public was largely enthusiastic. Americans hoped that the existing Franco-American alliance would be solidified by democratic reforms that would transform France into a republican ally against aristocratic and monarchical Britain. However, with revolutionary change also came political instability, violence, and calls for radical social change in France that frightened many Americans. American political debate over the nature of the French Revolution exacerbated pre-existing political divisions and resulted in the alignment of the political elite along pro-French and pro-British lines. Secretary of State Thomas Jefferson became the leader of the pro-French Democratic-Republican party that celebrated the republican ideals of the French Revolution. Secretary of the Treasury Alexander Hamilton led the Federalist Party, which viewed the Revolution with skepticism and sought to preserve existing commercial ties with Great Britain. With the two most powerful members of his cabinet locked in mutual opposition, President George Washington tried to strike a balance between the two.

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.

In 1794, the French Revolution entered its most violent phase, the Terror. Under foreign invasion, the French Government had declared a state of emergency, and many foreigners residing in France were arrested, including American revolutionary pamphleteer Thomas Paine, owing to his British birth. Although American minister to France Gouverneur Morris did not obtain Paine's release, Morris was able to intercede successfully on behalf many Americans imprisoned during the Terror, including the American consuls at Dunkirk, Rouen, and Le Havre. Once the Terror ended in late July of 1794, the arrests ended, and Paine, who had been scheduled to be executed, was released.
