Arizona was originally a part of the Mexican state of Sonora before being taken over by the United States in 1848 as a result of the Mexican-American War. It started as part of the Territory of New Mexico but split into its own territory in 1863. Arizona became a state in 1912, beginning mainly as a rural area depending on agriculture, but during the 1940s, the state saw a boom in population as people began to appreciate the warm climate.
