History and Growth

The history of Phoenix is one of resilience and expansion. Long before the modern city, the region was inhabited by the Hohokam people, who developed sophisticated irrigation systems to farm the desert.

The modern city was settled in 1867 and officially incorporated on February 25, 1881. Founded by Jack Swilling and named after the mythical phoenix bird—symbolizing a city rising from the ruins of the Hohokam canals—the settlement grew steadily through the early 20th century.

The Phillip Darrell Duppa adobe house was built in 1870 and is the oldest house in Phoenix. The homestead is named after "Lord" Darrell Duppa, an Englishman who is credited with naming Phoenix and Tempe as well as founding the town of New River.

Following World War II, Phoenix experienced explosive growth. The introduction of widespread air conditioning and the development of the Central Arizona Project (CAP), a massive canal system designed to bring water from the Colorado River, allowed the city to expand rapidly into the desert.

By the mid-20th century, the cityscape shifted from a small agricultural town to a major urban center, as seen in the development of Central Avenue and the rising skyline of the 1940s.

Geography and Climate

Phoenix is situated in the Sonoran Desert, an ecosystem known for its unique flora and fauna. The city is characterized by its flat valley floor punctuated by dramatic mountain ranges, such as the South Mountains and Camelback Mountain.

The climate is arid and extreme. Summer temperatures frequently exceed 110°F, while winters remain mild. A notable weather phenomenon in the region is the haboob—a massive wall of dust pushed by monsoon thunderstorms that can sweep across the valley.
