Who is referred to as the "Prince of the Constitution"?

The title "Prince of the Constitution" is attributed to James Madison primarily due to his instrumental role in the drafting and promotion of the United States Constitution. Madison's contributions were crucial not only in the development of the framework for government but also in the advocacy for its ratification through the Federalist Papers, which he co-authored with Hamilton and John Jay. His deep understanding of political theory and governance, combined with his practical political experience, positioned him as a leading figure in the Constitutional Convention of 1787, where he presented the Virginia Plan that laid the foundation for much of the Constitution's structure.

Madison's vision for a balanced government—which included checks and balances and a separation of powers—reflects the principles that are now fundamental to the American political system. Therefore, referring to him as the "Prince of the Constitution" acknowledges his significant influence in shaping the document that established the governance of the United States.
