Phoenix (/?fi?n?ks/) is the capital, and largest city, of the U.S. state of Arizona. With 1,563,025 people (as of 2015), Phoenix is the sixth most populous city nationwide, the most populous state capital in the United States, and the only state capital with a population of more than 1 million residents.
For more than 2,000 years, the Hohokam peoples occupied the land that would become Phoenix. The Hohokam created roughly 135 miles (217 km) of irrigation canals, making the desert land arable. Paths of these canals would later become used for the modernArizona Canal, Central Arizona Project Canal, and the Hayden-Rhodes Aqueduct. The Hohokam also carried out extensive trade with the nearby Anasazi, Mogollon and Sinagua, as well as with the more distant Mesoamerican civilizations. It is believed that between 1300 and 1450, periods of drought and severe floods led to the Hohokam civilization's abandonment of the area.
