ARIZONA
Marco de Niza, a Spanish Franciscan friar, was the first European to explore Arizona. He entered the area in 1539 in search of the mythical Seven Cities of Gold. Although he was followed a year later by another gold seeker, Francisco Vsquez de Coronado, most of the early settlement was for missionary purposes. In 1775 the Spanish established Fort Tucson. In 1848, after the Mexican War, most of the Arizona territory became part of the U.S., and the southern portion of the territory was added by the Gadsden Purchase in 1853.
