Two sets of actors were present politically at the founding of this country.Name them and explain what their fundamental differences were.

The two sets of actors present politically at the founding of the United States were the Federalists and the Anti-Federalists.

The Federalists, led by Alexander Hamilton, James Madison, and John Jay, were in favor of a strong central government and the ratification of the Constitution. They believed that a strong national government was necessary to maintain order and stability, and to protect the country from foreign threats. The Federalists also supported the idea of a national bank and a standing army, as well as a system of checks and balances to prevent any one branch of government from becoming too powerful.

On the other hand, the Anti-Federalists, led by Thomas Jefferson and Patrick Henry, were opposed to the ratification of the Constitution in its original form. They were concerned that a strong central government would infringe upon the rights of the states and the individual citizens. The Anti-Federalists argued for a more decentralized government, with power remaining primarily in the hands of the states. They also advocated for a Bill of Rights to protect individual liberties from potential government overreach.

The fundamental difference between the Federalists and the Anti-Federalists was their view on the role and power of the central government. The Federalists believed in a strong national government, while the Anti-Federalists favored a more limited and decentralized government with greater emphasis on states' rights. This debate ultimately led to the compromise that resulted in the inclusion of the Bill of Rights in the Constitution, addressing the concerns of the Anti-Federalists and paving the way for the ratification of the Constitution.
