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.
Since the 1950s, Arizona's population and economy have grown dramatically because of migration into the state, and now the state is a major hub of the Sun Belt. Cities such as Phoenix and Tucson have developed large, sprawling suburban areas. Many large companies, such as PetSmart and Circle K, have headquarters in the state, and Arizona is home to major universities, including the University of Arizona and Arizona State University. Traditionally, the state is politically known for national conservative figures such as Barry Goldwater and John McCain, though it voted Democratic in the 1996 presidential race and in the 2020 presidential and senatorial elections.
