5-Minute Guide to the
U.S. Constitution

The Constitution created our government. More than 200 years later, here’s how it affects you.

On September 17, 1787, our nation’s Founders created a document that continues to shape Americans’ lives today. That day, delegates to the Constitutional Convention in Philadelphia, ­Pennsylvania, signed the United States Constitution.

The Constitution is the supreme law of the land. It set up our federal (national) government, as well as the government’s relationship with the states and citizens. Amendments—which were added later—spell out important changes, including guarantees of Americans’ rights. Read on for a quick overview of the Constitution and how it works.


1. American colonists won independence from Great Britain in the Revolutionary War (1775-1783). After the war, the 13 original states established a country whose federal government had limited power.

2. Leaders called for a conference to form a stronger government. On May 25, 1787, delegates from most states met in Philadelphia for what would become known as the Constitutional Convention.

3. The delegates debated for nearly four months. Finally, 39 of the 55 delegates signed a newly written Constitution.

The U.S. Constitution outlines a system of  "checks and balances" to make sure that no one branch of the federal government has too much power.
