In addition to the Native American conflicts, there was also considerable tension between rural residents of Cochise County, who were for the most part Democrats from the agrarian Confederate States, and more urban residents living within the region's few developed towns, who were largely Republican business owners from the industrial Union States. The division created polarizing sectional alliances and culminated in countless local feuds, the most well-known of which has been called the Cochise County feud or the Earp–Clanton feud, which included the historic Gunfight at the O.K. Corral in the town of Tombstone and Wyatt Earp's Vendetta Ride in the early 1880s. Dr. George E. Goodfellow famously described Tombstone, the capital of Cochise County, as the "condensation of wickedness."
