The state of Colorado was organized as a U.S. territory on February 28, 1861 from parts of Kansas, Nebraska, Utah, and New Mexico territories. It includes land acquired by the U.S. under the Louisiana Purchase (1803), the Annexation of Texas (1845), and Mexican Cession (1848). Colorado was admitted to the Union on August 1, 1876.
