Answer:
Federalists were the group of people who believed in and fought for the ratification of the United States Constitution, while Anti-Federalists did not favor the ratification of the United States Constitution. Anti-Federalists appreciated the Articles of Confederation more and favored the U.S. Government having very limited powers, or having no power at all. For this reason, Federalists compromised with Anti-Federalists to draft a Bill of Rights, which lists the ten inalienable rights of any U.S. Citizen regardless.
Separation of Powers was a principle established in our government which is the reason for why the Judicial, Legislative, and Executive Branch exist. Separation of Powers was a way to make sure the government did not have too much power in one area than another, allowing them to keep each other in check from enacting abusive orders or actions.
