One notable supporter of the Constitution who was not an author of the Federalist Papers is George Washington. While Washington played a crucial role in the drafting and ratification of the Constitution and was a strong advocate for its adoption, he did not contribute to the Federalist Papers, a series of essays written to promote its ratification.
The Federalist Papers were primarily authored by James Madison, Alexander Hamilton, and John Jay. These essays were written to explain the merits of the proposed Constitution and to persuade the public and state legislatures to support it. Washington’s influence, however, was significant as he endorsed the Constitution and urged others to support it, but he did not pen any of the essays.
