Ever since Colorado has had a state capital, that capital has been Denver thanks to an 1881 referendum. But it wasn’t always Denver when looking back at Colorado’s territorial history.
Colorado’s land was originally split across four other territories: Kansas, Nebraska, New Mexico and Utah before the Territory of Colorado was formed on Feb. 28, 1861. Originally, the capital was placed in Colorado City (now Colorado Springs), but moved to Golden in 1862.
However, the legislature held meetings in Denver because it was “more of a city.” Finally, in 1867, the territory capital moved to Denver, where it’s been ever since.
