The Federalist Party was one of the first political parties in the United States, founded in the early 1790s, which advocated for a strong national government and a centralized authority. It emerged as a response to the weaknesses of the Articles of Confederation and supported policies such as a national bank, tariffs, and a robust military. The party played a significant role during the presidencies of George Washington and John Adams, particularly during Adams' presidency when it supported controversial legislation like the Alien and Sedition Acts.
