This landmark collection of eighty-five essays, written under the pseudonym "Publius," was composed to explain and defend the ratification of the United States Constitution. Through rigorous arguments on federalism, separation of powers, checks and balances, and the protection of liberty, the authors present one of the most influential analyses of democratic government ever written. Essential for students of political science, constitutional law, and public administration, The Federalist Papers remains a foundational work for understanding the principles and practical design of modern constitutional democracy.
