While economic policies were the original motivating factor in the growing partisan split, foreign policy also became a factor. Though most Americans supported the French Revolution before the Execution of Louis XVI, some of Hamilton's followers began to fear the radical egalitarianism of the revolution as it became increasingly violent. Washington particularly feared British entrance into the war, as he worried that sympathy for France and hatred for Britain would propel the United States into the French Revolutionary Wars, to the ruin of the American economy. In 1793, after Britain entered the French Revolutionary Wars, several Democratic-Republican Societies were formed. These societies, centered on the middle class of several eastern cities, opposed Hamilton's economic policies and supported France. Conservatives came to fear these societies as populist movements that sought to re-make the class order. That same year, the British began seizing American merchantmen who were trading with France, fanning the flames of anti-British sentiment. As Washington continued to seek peace with Great Britain, critics finally began to attack the president himself.
