Constitution Day and Citizenship Day

Featured Content
Commemorating the formation and signing of the U.S. Constitution, and recognizing those who have become U.S. citizens

The signing of the United States Constitution on September 17, 1787, by delegates to the Constitutional Convention established America’s national government and fundamental laws. At the 1787 convention delegates formulated a plan for a stronger government establishing three branches – Legislative, Executive, and Judicial – along with a system of checks and balances ensuring no single branch would have too much power.

It wasn’t until 2004 that the holiday took on the full name it bears today. In 2004, a law was enacted renaming the holiday “Constitution Day and Citizenship Day,” (36 U.S.C. 106) requiring public schools and institutions to provide information on the history of the country’s Constitution.
