America 250 - Colorado 150
In 2026, Colorado will observe two significant anniversaries. We invite you to join us in this opportunity to remember our shared past and imagine our future together.
The America 250 / Colorado 150 Commission is dedicated to honoring the diverse experiences of all who have called Colorado home, recognizing that our state’s history is intricately woven into the broader American story. As the nation celebrates the 250th anniversary of the Declaration of Independence in 2026, Colorado will simultaneously commemorate its 150th anniversary of statehood, marking a historic and uniquely unified celebration. Check out the CDE Social Studies Page.
Colorado’s anniversaries will be an opportunity for every Coloradan to come together as we:
-
Celebrate Colorado by acknowledging our complete history
-
Honor what makes Colorado unique
-
Embrace our shared destiny as we strive toward a more perfect union
There are numerous opportunities to get involved!

"In 2026, the United States will mark the 250th anniversary of the Declaration of Independence—our nation’s semiquincentennial. At the same time, Colorado will mark the 150th anniversary of our entrance into the Union—our state’s sesquicentennial. As the Centennial State, Colorado is the only one who will observe twin anniversaries—our Sesquisemiquincentennial."
