The Federalist Papers argued for the ratification of the United States Constitution during the 1780s. The eighty five essays, written mostly by Alexander Hamilton, James Madison and John Jay, outlined the functioning of the proposed government, set forth the powers and responsibilities of each branch, and defended its constitutional form. They argued that the Constitution would provide a strong federal government, with a one-house legislature that would be fully adequate to the national defence and security, and that the powers enumerated to it would be neither oppressive nor inadequate. They also argued for a balanced view between state and federal power, highlighting that both were necessary for a healthy nation.

The Federalist Papers also argued for a system of checks and balances in order to prevent any of the branches from becoming too powerful. They argued that by dispersing power throughout the three branches of government, it would prevent tyranny and ensure that no one branch or person held too much power. Hamilton wrote that no man is allowed to be a judge in his own cause, because his interest would certainly bias his judgment, and, not improbably, corrupt his integrity.

The Federalist Papers argued for a strong system of governmental checks and balances and for a strong federal government with clear powers and responsibilities in order to ensure a functional nation. They presented a very logical and compelling argument for the ratification of the Constitution and are still relevant today, as they provide insight into the functioning of the American government.
