Arizona is a state in the Western United States, grouped in the Southwestern and occasionally Mountain subregions. Arizona is the 48th state and last of the contiguous states to be admitted to the Union, achieving statehood on February 14, 1912.
Historically part of the territory of Alta California in New Spain, it became part of independent Mexico in 1821. After being defeated in the Mexican–American War, Mexico ceded much of this territory to the United States in 1848. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase.
The state’s name appears to originate from an earlier Spanish name, Arizonac, derived from the O’odham name alĭ ṣonak, meaning “small spring”, which initially applied only to an area near the silver mining camp of Planchas de Plata, Sonora. To the European settlers, their pronunciation sounded like Arissona.
Arizona is located in the southwestern quadrant of the conterminous states, bordered by California to the west, Nevada to the northwest, Utah to the north, New Mexico to the east, and the Mexican state of Sonora to the south.
