Colorado was admitted to the Union as the 38th state on this day, August 1, 1876 — 137 years ago. Back in 1926, Leroy Hafen, the premier Colorado historian at the time, along with other historians celebrated Colorado’s then 50th birthday with a series of articles on Colorado statehood in the August 1926 issue of Colorado Magazine, which you can check out from our library. Also in our library you can find Hafen’s excellent 5-volume History of Colorado, published in 1927 and just recently digitized. Over the years, Colorado magazine has featured several other articles on Colorado’s statehood. Contact our library if you would like to check out Colorado Magazine, Hafen’s History of Colorado, or any of our other publications.
