Constitution Day and Citizenship Day
What is Constitution Day?
September 17 is recognized in the United States as Constitution Day and Citizenship Day. On this day, we commemorate the creation and signing of the supreme law of the land and celebrate the privileges and responsibilities of U.S. citizenship, be it for native-born or naturalized citizens.
Federal law requires that all schools receiving federal funds hold an educational program for their students on September 17 of each year.

The Framers of the Constitution
Fifty-five delegates were present at the Constitutional Convention, which was held in Philadelphia in the summer of 1787. Below is a selection of biographies of different Framers who helped shape America’s constitutional democracy all those years ago.
-
Benjamin Franklin was a Founding Father, inventor, writer, diplomat, and statesman who played a major role in creating the United States. A successful printer and the author of Poor Richard's Almanack, Franklin became one of the colonies' most influential voices. He proposed the Albany Plan of Union, helped organize colonial resistance to British policies, and served in the Second Continental Congress. Franklin helped draft and signed the Declaration of Independence, negotiated crucial French support during the Revolutionary War, and helped secure the Treaty of Paris in 1783, ending the war. He also signed the U.S. Constitution and supported compromise during the Constitutional Convention. Beyond government, Franklin founded important civic institutions, including libraries and the American Philosophical Society, and gained worldwide fame for his scientific discoveries, especially his experiments with electricity.
-
Elbridge Gerry was a Founding Father, signer of the Declaration of Independence, diplomat, governor of Massachusetts, and the fifth U.S. vice president, under James Madison. A strong supporter of American independence, he helped organize military supplies during the Revolutionary War and served in the Continental Congress. Gerry attended the Constitutional Convention and helped shape ideas about checks and balances and the Electoral College, but he refused to sign the Constitution because it lacked a bill of rights and gave too much power to the federal government. He later supported the new government and served in Congress, where he defended states' rights and civilian control over the military. As governor of Massachusetts, his administration became linked to partisan redistricting after a distorted voting district inspired the term gerrymandering. Despite criticism, Gerry spent his career focused on protecting republican government and national unity.
-
Alexander Hamilton was a Founding Father, Revolutionary War officer, and the first U.S. secretary of the treasury. Born in the Caribbean, he became George Washington's trusted aide during the Revolution and later helped shape the new nation's government. Hamilton strongly supported a powerful federal government and played a key role in writing The Federalist, which helped secure ratification of the Constitution. As treasury secretary under Washington, he created the nation's financial foundation by establishing a national bank, funding the national debt, assuming state debts, and promoting manufacturing and trade. His policies strengthened the U.S. economy and federal authority. Hamilton also helped found the Federalist Party. Though controversial, his ideas greatly influenced the structure of American government and finance. He died in 1804 after a duel with Aaron Burr.
-
Thomas Jefferson was a Founding Father, principal author of the Declaration of Independence, and the third president of the United States. Influenced by Enlightenment ideas, he argued that people have natural rights and that government exists to protect life, liberty, and the pursuit of happiness. Jefferson served in the Continental Congress, as governor of Virginia, secretary of state, vice president, and president. He helped establish religious freedom through the Virginia Statute for Religious Freedom, which promoted separation of church and state. As president, he doubled the size of the United States through the Louisiana Purchase of 1803 and supported limited federal government and westward expansion. Jefferson also promoted public education, founding the University of Virginia. His ideas about democracy and individual rights greatly shaped American government, though his legacy is complicated by his ownership of enslaved people.
-
James Madison, known as the Father of the Constitution, played a central role in shaping the U.S. government. Born in Virginia and educated at Princeton, he became a strong supporter of a stronger national government after seeing the weaknesses of the Articles of Confederation. At the Constitutional Convention of 1787, Madison introduced the Virginia Plan and helped design the structure of the federal government. He coauthored The Federalist with Alexander Hamilton and John Jay, defending the Constitution and explaining ideas such as separation of powers and checks and balances. To secure ratification, Madison promised a bill of rights and later wrote the first 10 amendments, protecting freedoms such as speech, religion, and the press. Madison also served as secretary of state under Thomas Jefferson and as the fourth U.S. president, leading the nation during the War of 1812. His work helped define American democracy, constitutional government, and individual rights.
-
George Mason was a Virginia statesman and political thinker whose ideas strongly shaped American government and individual rights. A leader during the Revolutionary era, he wrote the Fairfax Resolves (1774), which challenged British taxation and helped influence the First Continental Congress. In 1776, Mason authored the Virginia Declaration of Rights, a groundbreaking document that inspired the Declaration of Independence and later the U.S. Bill of Rights. He also helped draft Virginia's constitution. At the Constitutional Convention in 1787, Mason argued against a powerful central government and warned about the dangers of concentrated political power. He refused to sign the Constitution because it lacked a bill of rights and objected to compromises involving slavery and federal authority. His "Objections to the Federal Constitution" became a key Anti-Federalist argument and helped lead to the adoption of the Bill of Rights, securing protections for individual liberties.
-
Gouverneur Morris was a statesman, constitutional framer, and influential architect of early American government. Born into a wealthy New York family, he was educated at King's College (now Columbia University). He supported American independence and served in the Continental Congress, where he signed the Articles of Confederation. Morris also helped create the nation's decimal coinage system and drafted plans for the Bank of North America. At the Constitutional Convention of 1787, Morris was one of the most active delegates, speaking more often than any other member. As part of the Committee on Style, he wrote much of the Constitution's final wording, including the famous phrase "We the People," emphasizing national unity and popular sovereignty. He also helped shape the presidency and proposed the Electoral College system. Later, Morris served as U.S. ambassador to France during the French Revolution and as a U.S. senator from New York.
-
George Washington was the commander of the Continental Army during the American Revolution and the first president of the United States. Born in Virginia, he gained military experience in the French and Indian War before leading American forces in the Revolutionary War, including the decisive battle at Yorktown in 1781 and final victory over the British. After the war, Washington strengthened republican government by voluntarily giving up military power and rejecting calls to become king. He presided over the Constitutional Convention of 1787, helping to legitimize the new Constitution, and was unanimously elected the nation's first president in 1788. Washington established key precedents for the presidency, including the cabinet system, the title "Mr. President," executive authority, and the tradition of a two-term limit. He promoted national unity, upheld federal authority during the Whiskey Rebellion, and warned against political parties and foreign alliances in his "Farewell Address."

The structure of the Constitution is built on three key principles: federalism, separation of powers, and checks and balances.

Article II of the Constitution creates the office of the president of the United States (POTUS), determines how they are selected, and states the oath of office where they swear to “preserve, protect, and defend the Constitution of the United States.” The 12th Amendment changed how the vice president is selected.
