In 1910, after Congress passed an enabling act that allowed Arizona to apply for statehood, a convention met at Phoenix and drafted a state constitution. On 14 February 1912, Arizona entered the Union as the 48th state.
During the first half of the 20th century, Arizona shook off its frontier past. World War I (1914–18) spurred the expansion of the copper industry, intensive agriculture, and livestock production. A copper tariff encouraged the mining industry, additional irrigation projects were started, and public works were begun on Indian reservations, in parks and forests, and at education institutions. Prosperity returned during World War II (1939–45) as camps for military training were built throughout the state. Meat, cotton, and copper markets flourished, and the construction of processing and assembly plants suggested a new direction for the state's economy.
Arizona emerged from World War II as a modern state. War industries spawned an expanding peacetime manufacturing boom that soon provided the principal source of income, followed by tourism, agriculture, and mining. The rise of Barry Goldwater of Phoenix to national prominence further grew the influence Arizona had on the nation. Meanwhile, air conditioning changed lifestyles, prompting a significant migration to the state.
Arizona continues to be recognized for its natural beauty, a high quality of life, and its ongoing innovation in all fields, from agriculture to technology. KSWT News 13 and our partners celebrate Arizona's milestone and reflect on Arizona's past, present, and future as well as our rich diversity of people, places, and progress.
