Which of the following was the most influential in ratifying the Constitution?

Speeches made by George Washington
The Declaration of Independence
Threats by King George
The Federalist Papers

The most influential factor in ratifying the Constitution was The Federalist Papers. They were a series of 85 essays written by Alexander Hamilton, James Madison, and John Jay, which were published in newspapers between 1787 and 1788. The papers argued in favor of ratifying the Constitution, addressed concerns raised by opponents, and presented a strong case for a strong centralized government, which ultimately swayed undecided voters in favor of ratification.
