Yes, you’re probably thinking, Colorado’s birthday is August 1! That is true, as Colorado became a state on August 1, 1876. However, today could also be recognized as Colorado’s birthday, because it was February 28, 1861 that Colorado Territory was organized. If there wasn’t a Colorado Territory, there wouldn’t have been a Colorado State! You can read a copy of the Territorial Enabling Act on the Colorado State Archives website. In our library, you can view a few publications dating back from territorial days, including the territorial statutes, House Journals and Council Journals, and Superintendent Reports.
