Arizona is one of the Four Corners states, situated south and east of the Colorado River.
Arizona was administered as part of the Territory of New Mexico until it was organized into a separate territory on February 24, 1863.
Arizona's representatives in the United States House of Representatives are Rick Renzi (R-1), Trent Franks (R-2), John Shadegg (R-3), Ed Pastor (D-4), J.D. Hayworth (R-5), Jeff Flake (R-6), Raul Grijalva (D-7), and Jim Kolbe (R-8).
Arizona's educational institutions include the Univ. of Arizona, at Tucson; Arizona State Univ., at Tempe; Northern Arizona Univ., at Flagstaff; and several private institutions.
Arizona's minerals, valued even by prehistoric miners, attracted most of the early explorers, and although the area remained a relatively obscure section of the Territory of New Mexico, mining continued sporadically.
Although Arizona's mines were not unionized until the mid-1930s, strikes occurred at the copper mines of Clifton and Morenci in 1915 and at the Bisbee mines in 1917.
