The Frente Popular or Popular Front in Spain's Second Republic was an electoral coalition and pact signed in January 1936 by various left-wing political organisations for the purpose of contesting that year's election. In July 1936, Francisco Franco instigated a coup d'état which started the Spanish Civil War (1936–1939). After a protracted war of attrition Franco would defeat the Republican forces and rule Spain as a dictatorship until he died in 1975. This poster was asking for amnesty in favor of the Popular Front.
