What is the capital of Arizona?

Phoenix is the capital city of Arizona. It is also the largest city in Arizona, with a population of 1,445,632 people according to the 2010 Census. This makes Phoenix the sixth most populous city in the United States, although its population density is low compared to other major cities.

Phoenix was first settled as an agricultural community in 1867 and became incorporated as a city in 1881. The arrival of the railroad in the last two decades of the 19th century transformed the city's economy, making it an important trading post in the American southwest. In 1912, Phoenix officially became the capital city of Arizona, which had recently earned statehood.
