Federalist Papers
In order to help convince their fellow Americans of their view that the Constitution would not threaten freedom, James Madison, Alexander Hamilton, and John Jay teamed up in 1788 to write a series of essays in defense of the Constitution. The essays, which appeared in newspapers addressed to the people of the state of New York, are known as the Federalist Papers. They are regarded as one of the most authoritative sources on the meaning of the Constitution, including constitutional principles such as checks and balances, federalism, and separation of powers.
