Nogales inhabits La Frontera, the Arizona-Mexico border country that exists as much as a state of mind as a place. Here among the saguaro under the Sonoran desert sun came conquerors under the flags of Spain, Mexico, the United States, and the Confederate States. From the arrival of Fray Marcos de Niza in the Ambos Nogales territory in 1539 when Nogales was part of New Spain, through the marches of Conquistadores along Spain's El Camino Real or Royal Road, to the exploits of Apache warriors and the Mexican revolutionary Pancho Villa, Nogales has been at the center of life on the frontier. Nogales: Life and Times on the Frontier explores the rich history of this area seasoned by cultures from across the border and around the world. Tales of the bustling ranching, railroad, mining, military, and produce industries are brought to life through the eyes of figures like rancher Pete Kitchen and West Point's first African-American graduate Henry Ossian Flipper. These unique stories are highlighted by striking images from vintage postcards, period photographs, detailed maps, and other illustrations that chronicle the journey from lonely Spanish outpost to thriving modern gateway.
