The Three-Fifths Compromise: This compromise addressed the issue of how slaves would be counted in determining a state's population. The Federalists wanted slaves to be counted fully, which would have given Southern states more power in the federal government. The Anti-Federalists wanted slaves to not be counted at all, which would have given Northern states more power. The compromise counted slaves as three-fifths of a person for the purposes of determining population.
The Commerce Compromise: This compromise addressed the issue of how the federal government would regulate interstate commerce. The Federalists wanted the federal government to have the power to regulate interstate commerce, while the Anti-Federalists wanted the states to retain this power. The compromise gave the federal government the power to regulate interstate commerce, but it also prohibited states from imposing tariffs or duties on imports or exports from other states.
The Bill of Rights: The Bill of Rights was not technically a compromise between Federalists and Anti-Federalists, but it was added to the Constitution in response to concerns raised by the Anti-Federalists. The Bill of Rights guaranteed certain individual rights and freedoms, such as freedom of speech, religion, and assembly.
These four compromises were essential in securing the ratification of the Constitution by the states. Without them, it is likely that the Constitution would have been rejected, and the United States would not have been formed.
