Arizona is the sixth largest state in the United States of America in terms of area and is nicknamed "The Grand Canyon State" as it is probably best known for that geographical feature.

Spanish explorers first arrived in Arizona in the 1530s, but the territory was part of Mexico through the 1840s until the Mexican-American War in 1848 when the US took control. In 1912, Arizona became the 48th state in the Union.

Manufacturing has become Arizona's most important industry. Principal products include electrical, communications, and aeronautical items. The state produces over half of the country's copper. Agriculture is also important to the state's economy. Top commodities are cattle and calves, dairy products, and cotton. In 1973 one of the world's largest dams, the New Cornelia Tailings, was completed near Ajo.
