The historical roots of present-day political parties can be traced back to early factions and ideological movements. For example, the Federalists and Democratic-Republicans were among the first political parties in the United States, emerging in the late 18th century. Their competition laid the groundwork for modern party systems by establishing key platforms that influenced subsequent parties. Over time, changing social, economic, and political contexts have led to the evolution of party ideologies, significantly shaping today’s political landscape and voter alignment.
