The history of Arizona encompasses Spanish, Mexican, and American periods. Arizona was part of the state of Sonora, Mexico from 1822, but the settled population was small. In 1848, under the terms of the Mexican Cession the United States took possession of Arizona above the Gila River after the Mexican War, which became part of the Territory of New Mexico. By means of the Gadsden Purchase, the United States secured the northern part of the state of Sonora, which is now Arizona south of the Gila River in 1854.

Prior to the adoption of its name for a U.S. state, Arizona was traditionally defined as the region south of the Gila River to the present-day Mexican border, and between the Colorado River and the Rio Grande. It encompasses present-day Southern Arizona and the New Mexico Bootheel plus adjacent parts of Southwestern New Mexico. This area was transferred from Mexico to the United States in the Gadsden Purchase of 1853.

Tropical Storm Octave was considered the worst tropical cyclone in the history of Arizona, whose remnants caused devastating and record-breaking flooding in the state. The nineteenth tropical cyclone and fifteenth named storm of the 1983 Pacific hurricane season, the origins of Tropical Storm Octave were from a tropical disturbance that formed south of the Gulf of Tehuantepec on September 23, 1983. Steered by a deep layer high over Mexico, the disturbance moved west for four days before becoming a tropical depression on September 27 off the southwest coast of Mexico. Over an area of warm sea surface temperatures, it was able to quickly strengthen to peak winds of 50 mph (85 km/h), through wind shear prevented much further development. By September 30, Octave was accelerating to the northeast, steadily weakening due to cooler waters. That day it weakened to tropical depression status, and on October 2, Octave dissipated.
Southern Emigrant Trail, also known as the Gila Trail, the Kearny Trail, Southern Trail and the Butterfield Stage Trail, was a major land route for immigration into California from the eastern United States that followed the Santa Fe Trail to New Mexico during the California Gold Rush. Unlike the more northern routes, pioneer wagons could travel year round, mountain passes not being blocked by snows, however it had the disadvantage of summer heat and lack of water in the desert regions through which it passed in New Mexico Territory and the Colorado Desert of California. Subsequently, it was a route of travel and commerce between the eastern United States and California. Many herds of cattle and sheep were driven along this route and it was followed by the San Antonio-San Diego Mail Line in 1857-1858 and then the Butterfield Overland Mail from 1858 - 1861.
The Butterfield Overland Mail was a transport and mail delivery system that employed stagecoaches that travelled on a specific route between St. Louis, Missouri and San Francisco, California and which passed through the New Mexico Territory. It was created by the United States Congress on March 3, 1857, and operated until March 30, 1861. The route that was operated extended from where the ferry across the Colorado River to Fort Yuma Station, California was located, through New Mexico Territory via, Tucson to the Rio Grande and Mesilla, New Mexico then south to Franklin, Texas, midpoint on the route. The New Mexico Territory mail route was divided into two divisions each under a superintendent. Tucson was the headquarters of the 3rd Division of the Butterfield Overland Mail Company.
