Map of the states and territories of the United States as it was from February 4 1861 to February 28 1861. On February 4 1861, the Confederate States of America was created. Several states had seceded from the union on dates prior to this, and joined the CSA at different dates. To simplify the map, only the proclamation of the CSA is noted here. On February 28, Colorado Territory was created from portions of Utah, New Mexico, Nebraska, and the previous Kansas Territories.
