Flagstaff is a city in, and the county seat of, Coconino County in northern Arizona, in the southwestern United States. Established as a modern settlement in 1876 and incorporated as a city in 1928, the land had previously been lived on by native peoples of the southwest, primarily the Sinagua. Mountaineer Antoine Leroux then traveled the area, with Edward Fitzgerald Beale following in his footsteps and establishing a trail through the city in the mid-1800s. With a local spring, a small settlement grew by the wagon road, and the town was dominated by the McMillan, Riordan, and Babbitt families. Focused on agricultural pursuits, these families constructed some historic red stone buildings that still stand today.
