Abstract
The triumph of the Sandinista Revolution on July 19, 1979 marked the beginning of a period of intensification of the struggle of the insurgent movements in El Salvador and Guatemala that, encouraged by the victory of their Sandinista comrades, tried to emulate the defeat of the oligarchy in their respective countries. Nicaragua acquired a relevant role as it had not had in the region until then, becoming one of the actors that would mark the course of the isthmus during the eighties of the last century. One of the effects of this new role was the strengthening of relations between the Sandinista National Liberation Front and the Nicaraguan government with the guerrillas of the Farabundo Martí National Liberation Front of El Salvador and the National Revolutionary Unity. of Guatemala. The climate of revolutionary optimism that very graphically expressed this Central American vision of the revolution was summed up in the motto of the time: "If Nicaragua won, El Salvador will win and Guatemala will follow." The objective of this article is to describe and analyze the relationships that were forged between the FSLN, the FMLN and the URNG in the 1980s.
