Who is known as the “Father of the Constitution” in the United States?

James Madison is known as the "Father of the Constitution" due to his pivotal role in the document's drafting and his influential contributions to its philosophical underpinnings. Madison not only played a significant part in the Constitutional Convention of 1787 but also demonstrated remarkable leadership in advocating for a strong central government and the principles of republicanism. His extensive notes during the convention provided valuable insights into the debates and discussions that shaped the Constitution.

Additionally, Madison was a key figure in the ratification process, where he, alongside Alexander Hamilton and John Jay, wrote the Federalist Papers to defend the Constitution and persuade states to adopt it. His understanding of the necessity for a balance of powers and checks and balances significantly influenced the final document. Thus, his contributions earned him this distinguished title, making him an essential figure in American history and governance.
