The Arizona Territory was established in 1863, during the American Civil War, when it was separated from the larger New Mexico Territory. It became a significant area for mining, agriculture, and ranching, attracting settlers and prospectors. The territory was officially organized as a U.S. territory, allowing for a local government and representation in Congress. In 1912, the Arizona Territory became the 48th state of the United States. The region is known for its diverse landscapes, including deserts, mountains, and the famous Grand Canyon. The territory's history is marked by the influence of Native American tribes, such as the Navajo and Apache, who have lived in the area for centuries.
