Solomon, originally known as Solomonville, carries some of the deepest territorial history in the Gila Valley. It was founded by Isadore and Anna Solomon, who arrived in the area in 1876 to burn charcoal for the Lesinsky Brothers' copper smelter operation near Clifton. From that industrial beginning, Solomonville grew into a genuine seat of power in the region: it served as the Graham County seat from 1873/1874 until 1915, when a countywide election moved the county government to Safford.
Isadore Solomon himself became a central figure in the valley's early development — he worked as a merchant and postmaster, served as the county's first treasurer, and co-founded the Gila Valley Bank. Under his influence, the community grew substantially, with its population peaking at over 1,000 residents sometime between the 1880s and 1910, a considerable size for the territory at the time.
Today, Solomon is a much quieter riverside community along the Gila River, a short drive east of Safford. Little remains of its bustling territorial-era commerce, but the town's role as a former county seat and home to one of the valley's most influential pioneer families still shapes how locals talk about Graham County's early history.
