Answer:
Political parties developed during Washington's administration despite his opposition to them because there was a clear difference of opinion about federal and state power.
Explanation:
In the minds of most of the Founding Fathers a republican conception prevailed regarding the regime they were creating, where the search for the common good was above the political rivalries, and therefore, the factions had no place in the new system erected after the independence. The Federalists became the defenders of this project, contributing the first two Presidents, the venerated George Washington, elected unanimously for two consecutive terms, and the troubled John Adams, who despite releasing the White House, could not reissue the success of its predecessor, precisely because of the advent of the first party system in the United States.
After the victory over London, and in the heat of the debate over the new Constitution that should replace the Articles of the Confederation to create a federal Union, the Federalists, supporters of a Federal State with broad powers, won the game to the Anti-Federalists , defenders of the prerogatives of the different states. Anyway, numerous claims and fears of the Antifederalists nourished the ideas of those who would later oppose the alleged aristocratic tendencies of the Federalists.
