This year marks the 150th anniversary of Colorado statehood (it’s our sesquicentennial). At the same time, America is celebrating 250 years since signing the Declaration of Independence (its semiquincentennial).

Together, in 2026, Colorado and America celebrate our Sesquisemiquincentennial, or what we call the 250-150 for short!

This once-in-a-lifetime moment is an opportunity to reflect on our shared history, celebrate our communities, and shape the future together. These statewide efforts are being led by the America 250 – Colorado 150 Commission, and communities across our state are planning celebrations. 

The Colorado Department of Agriculture has been planning projects and events to mark these important anniversaries with the theme of “Setting Colorado’s Table: 150 Years of Agricultural Legacy.” Visit their website for details on projects and ways to join the fun!
