George Washington, the first President of the United States, warned political parties that they could lead to disunity and extremism in the country. In his Farewell Address, delivered on September 17, 1796, Washington emphasized the importance of national unity and cautioned against the influence of political parties. He believed that parties could divide the nation, cause conflict, and promote sectionalism over national interest. Washington's concerns were based on the early experiences of political partisanship in the United States, which were characterized by intense competition, ideological divisions, and sectional tensions. He feared that parties could undermine the strength and stability of the new nation and jeopardize the democratic principles upon which it was founded. Washington's warning served as a reminder of the importance of moderation, compromise, and statesmanship in maintaining the unity and well-being of the country.
