In this region there were some notable events, as the Apache insurrection, when Geronimo took refuge in the mountains of this region when generals Crook and Miles fought him in Arizona. The most notable Apache raids were in 1870, when the priest Echevería was killed in the town, and in 1882, when the distinguished scholar Leocadio Salcedo was killed at the La Noria ranch. Residents of the region also had problems with Yaqui uprisings and insurrections of the late 19th and early 20th centuries. On September 5, 1998, the state legislature gave it the title of Heroic City, in recognition of its defense by liberals against imperialists in the French Intervention.
