           The U.S. acquired the northern part of Arizona in 1848 with the Treaty of                                        Guadalupe Hidalgo. The area south of the Gila River was added in 1853 with                                the 1853 Gadsden Purchase. At first, Arizona was a part of the Territory of                                    New Mexico. Arizona became a separate territory in 1863. The U.S. made                                    Arizona the 48th state in 1912.
