An international history of radical movements and their convergences during the Mexican Revolution. The Mexican Revolution was a global event that catalyzed international radicals in unexpected sites and struggles. Tracing the paths of figures like Black American artist Elizabeth Catlett, Indian anti-colonial activist M.N. Roy, Mexican revolutionary leader Ricardo Flores Magón, Okinawan migrant organizer Paul Shinsei Kōchi, and Soviet feminist Alexandra Kollontai, Arise! reveals how activists around the world found inspiration and solidarity in revolutionary Mexico. From art collectives and farm worker strikes to prison “universities,” Arise! reconstructs how this era’s radical organizers found new ways to fight global capitalism. Drawing on prison records, surveillance data, memoirs, oral histories, visual art, and a rich trove of untapped sources, Christina Heatherton considers how disparate revolutionary traditions merged in unanticipated alliances. From her unique vantage point, she charts the remarkable impact of the Mexican Revolution as radicals in this critical era forged an anti-racist internationalism from below.
