The Anti-Federalists were a group of people who opposed the ratification of the Constitution.

The Anti-Federalists had a number of concerns about the Constitution, including that it would lead to a monarchy, that the federal government would be too powerful, and that it did not protect individual rights.

The Federalists argued that the Constitution would create a strong and stable government, that it protected individual rights, and that it would promote economic prosperity.

Federalist No. 85 was written by Alexander Hamilton and argued for a strong executive branch.

The Bill of Rights was a document that outlined the rights that the Anti-Federalists wanted to see added to the Constitution.

The Bill of Rights included 10 amendments.

The First Amendment to the Constitution protects freedom of speech.

The Second Amendment to the Constitution protects the right to bear arms.

The Third Amendment to the Constitution prohibits the government from quartering soldiers in private homes without the owner's consent.
