Some of the Founding Fathers argued strongly for federalism, especially James Madison, Alexander Hamilton, and John Jay. They created the strongest defense of the new Constitution in a book called "The Federalist" Papers. This was a collection of 85 essays supporting federalism. Its goal was to convince people to vote to ratify the Constitution. Although they were published anonymously at the time (with nobody's real names listed), the essays were written by Madison, Hamilton, and Jay. The essays explained the new Constitution and all the protections in it. It answered many of the arguments against federalism, and explained how the Constitution would help protect people's rights. For example, in "Federalist No. 10," James Madison wrote that federalism would help protect the republican values most Americans supported, like the importance of personal freedoms.
