Biography
Ricardo Flores Magón was a Mexican anarchist journalist and revolutionary organizer whose writing and organizing helped inspire the Mexican Revolution and shaped cross-border radical networks. Through the Partido Liberal Mexicano and allied publications, he promoted anti-authoritarian politics, labor militancy, and resistance to dictatorship, drawing repeated arrests in both Mexico and the United States. U.S. authorities prosecuted him multiple times, including a major World War I–era case in which he was arrested in 1918, convicted under the Espionage Act for antiwar writings, and sentenced to 20 years in federal prison. He died in custody in 1922 at Leavenworth, leaving a legacy defined by revolutionary agitation and the high costs of dissent.
The March1922 official report lists Richardo Flores Magon in List1 of convicted prisoners or parolees. The government entry reports Conspiracy and violating the espionage act, etc. a sentence of July 19, 1918, 21 years and 1 day, McNeil Island Penitentiary; July 23, 1920, transferred to Leavenworth.. Imposed terms, projected term-expiration dates, parole eligibility and intervals on bond are different measures; none is entered as a complete actual custody total. This attributed government entry is retained alongside the independently established individual chronology. [PDF13]
