Historical Facts About Arizona

The territory of Arizona was home to Native Americans for thousands of years. In fact, it still has the second largest population of indigenous peoples in the U.S. Over a quarter of the state’s land belongs to reservations. Some of the contemporary tribes living in Arizona include the Navajo, the Mohave, the Quechan, and the Ute. Although experts aren’t in complete agreement, many believe that the name Arizona originated from a Native American word meaning “small spring.”

The first European known to explore the area was Marcos de Niza, a Spaniard. Other Spanish explorers followed, and the territory became part of New Spain. Mexico claimed the territory in 1821 when they won their independence from Spain,then the land was ceded to America following the Mexican-American War. The area was originally administered as part of New Mexico and it stayed a “territory” until President Taft finally officially admitted it into the Union in 1912.
