Until the Mexican-American War (1846–48) only a few Americans—explorers, soldiers, trappers, sheep drivers—visited Arizona.

In 1883 workers completed the Atchison, Topeka and Santa Fe Railway across northern Arizona, thereby linking St. Louis, Missouri, with California; that same year the Southern Pacific Railroad completed a line from New Orleans to Los Angeles by way of Tucson and Yuma.
