Federalist No. 10
Federalist No. 10, authored by James Madison under the pen name Publius, is the tenth of 85 essays. Titled "The Same Subject Continued: The Union as a Safeguard Against Domestic Faction and Insurrection", Madison continues Hamilton's argument while developing themes of his own, such as the observation that representative republics contain greater safeguards against faction than do democracies.
Federalist 10 is often regarded by historians as the most important in the series.
It was published on November 22, 1787.
