In the years before the Mexican Revolution, Ricardo Flores Magón and the Partido Liberal Mexicano—along with their newspaper, Regeneración—organized workers throughout the Borderlands and were especially active among copper miners. In 1905, smelter and railroad workers founded a Liberal Club in Douglas, Arizona, sister city to Agua Prieta, Sonora. In 1906, the Party staged a series of armed forays into Mexico, members in Douglas were arrested before they could join, and the documents seized in that raid were used in the 1909 Tombstone trial against Flores Magón and his companions. The Douglas Club was back in the news a year later. This website includes a brief account of those events, along with a selection of photos, additional information, and a PLEA TO ANYONE WHO HAS INFORMATION ABOUT ELDERS WHO MIGHT HAVE BEEN IN THE PLM OR THE DOUGLAS OR BISBEE LABOR MOVEMENT between 1900 and 1920, to let us know.
