The United States Constitution, drafted in 1787, does not explicitly mention political parties. The framers of the Constitution did not anticipate the development of political parties as we understand them today. The Constitution outlines the structure of the federal government, the powers of its branches, and the rights of citizens, but it does not provide guidance on the formation or operation of political parties.
The emergence of political parties in the United States occurred in the years following the ratification of the Constitution, with figures like Alexander Hamilton and Thomas Jefferson leading opposing factions. The Constitution has since accommodated the existence of political parties through amendments and the development of constitutional conventions and interpretations by the courts.
