Initially published in three New York newspapers, the Federalist Papers are 85 essays written between October 1787 and May 1788. They were composed by three different authors: Alexander Hamilton, John Jay, and James Madison, all under the single anonymous pseudonym ‘Publius’. In these essays, Publius argues for approval of the United States Constitution, which had been sent to the states for ratification in the Fall of 1787. Today, these essays serve as a primary source for the interpretation of the United States Constitution. The essays are all narrated here, included as one of the greatest series to appear in American newspapers.
