Constitutional Convention begins | May 25, 1787

S E E D E D   C O N T E N T

Four years after the United States won its independence from Great Britain, 55 state delegates, including George Washington, James Madison and Benjamin Franklin, convene in Philadelphia to compose a new U.S. constitution on May 25, 1787.

The Articles of Confederation, ratified several months before the British surrender at Yorktown in 1781, provided for a loose confederation of U.S. states, which were sovereign in most of their affairs. On paper, Congress—the central authority—had the power to govern foreign affairs, conduct war, and regulate currency, but in practice these powers were sharply limited because Congress was given no authority to enforce its requests to the states for money or troops. By 1786, it was apparent that the Union would soon break up if the Articles of Confederation were not amended or replaced. Five states met in Annapolis, Maryland, to discuss the issue, and all the states were invited to send delegates to a new constitutional convention to be held in Philadelphia.

History Shorts: Who Wrote the U.S. Constitution?

The U.S. Constitution was a group effort of some of the country's greatest minds, but the bulk of the document can actually be credited to one Founding Father.

On May 25, 1787, delegates representing every state except Rhode Island convened at Philadelphia's Pennsylvania State House for the Constitutional Convention. The building, which is now known as Independence Hall, had earlier seen the drafting of the Declaration of Independence and the signing of the Articles of Confederation. The assembly immediately discarded the idea of amending the Articles of Confederation and set about drawing up a new scheme of government. Revolutionary War hero George Washington, a delegate from Virginia, was elected convention president.

During three months of debate, the delegates devised a brilliant federal system characterized by an intricate system of checks and balances. The convention was divided over the issue of state representation in Congress, as more populated states sought proportional legislation, and smaller states wanted equal representation. The problem was resolved by the Connecticut Compromise, which proposed a bicameral legislature with proportional representation in the lower house (House of Representatives) and equal representation of the states in the upper house (Senate).

On September 17, 1787, the Constitution of the United States of America was signed by 38 of the 41 delegates present at the conclusion of the convention. As dictated by Article VII, the document would not become binding until it was ratified by nine of the 13 states.

Beginning on December 7, five states—Delaware, Pennsylvania, New Jersey, Georgia, and Connecticut—ratified it in quick succession. However, other states, especially Massachusetts, opposed the document, as it failed to reserve un-delegated powers to the states and lacked constitutional protection of basic political rights, such as freedom of speech, religion, and the press. In February 1788, a compromise was reached under which Massachusetts and other states would agree to ratify the document with the assurance that amendments would be immediately proposed. The Constitution was thus narrowly ratified in Massachusetts, followed by Maryland and South Carolina. On June 21, 1788, New Hampshire became the ninth state to ratify the document, and it was subsequently agreed that government under the U.S. Constitution would begin on March 4, 1789.

8 Things You Should Know About the Bill of Rights

The first 10 amendments to the U.S. Constitution, known collectively as the Bill of Rights, became law on December 15, 1791.

On September 25, 1789, the first Congress of the United States adopted 12 amendments to the U.S. Constitution-the Bill of Rights-and sent them to the states for ratification. Ten of these amendments were ratified in 1791. In November 1789, North Carolina became the 12th state to ratify the U.S. Constitution. Rhode Island, which opposed federal control of currency and was critical of compromise on the issue of slavery, resisted ratifying the Constitution until the U.S. government threatened to sever commercial relations with the state. On May 29, 1790, Rhode Island voted by two votes to ratify the document, and the last of the original 13 colonies joined the United States. Today the U.S. Constitution is the oldest written national constitution in operation in the world.
