The Territory of Arizona, commonly known as the Arizona Territory, was a territory of the United States that existed from February 24, 1863, until February 14, 1912, when the remaining extent of the territory was admitted to the Union as the state of Arizona. It was created from the western half of the New Mexico Territory during the American Civil War.
