In 1792, French Revolutionaries, inspired by Enlightenment philosophers, overthrew the French monarchy after not receiving more voting power they sought. The motto of the revolutionaries during the revolution was liberté, egalité, fraternité, French for "liberty, equality, and fraternity," taken from Robespierre's speech "On the organization of the National Guard." As a legislative body elected by the people French language replaced regional dialects. Napoleon, who became First Consul in 1799, utilized nationalistic pride to unify and spread the power of the country. He created the Napoleonic Code which unified French law, and he won a series of wars that raised French morale.
In the U.S. the Alien and Sedition Acts were passed because of Francophile eagerness to fight Britain alongside Napoleon. John Adams (under the auspices of Hamilton's Federalists cabinet) created these Acts which denied freedom of speech to an extent. This outraged Americans to not re-elect the Federalists (who had been in power for 12 years). As a practical matter, Napoleon sold land to finance his wars, and Thomas Jefferson purchased the Louisiana purchase. This doubled the size of the United States.
