On March 16, 1751, James Madison was born in Virginia. He later became the fourth president of the United States and is often called the “Father of the Constitution.” Madison played a central role in drafting the Constitution and the Bill of Rights. He co-authored many of The Federalist Papers, which argued for ratification of the new framework of government. As president, he led the nation during the War of 1812. Madison’s ideas on republican government and liberty continue to influence American political thought.
