America 250 - Colorado 150

In 2026, Colorado will observe two significant anniversaries: The 250th anniversary of the Declaration of Independence and the 150th anniversary of Colorado entering the Union. The 250th anniversary of our nation's founding document - our semiquincentennial - provides an opportunity to come together with our fellow Coloradans around the state and our fellow Americans around the ideals we share.

As the Centennial State, Coloradans also have a unique opportunity to celebrate the 150th anniversary of our statehood - our sesquicentennial - and what makes Colorado such a special place to call home. The America 250 - Colorado 150 Commission was established to guide Colorado's twin commemorations in ways that enable all Coloradans to participate. This website is where you can find information about the commission and how to get involved.
