Abstract
This article analyzes the role played by Argentine internationalists during the war led by the Sandinista National Liberation Front (FSLN) against the Somoza family’s dictatorship, as well as their participation in Nicaragua’s national reconstruction process between 1979 and 1984. It argues that their contribution manifested itself in five key areas: during the war, in the creation of guerrilla camps and the military training of Sandinista fighters; and, following the revolutionary victory, in the National Literacy Crusade, the National Health Campaign, and the political and economic reorganization promoted by the new government. The study is based on documentary, newspaper, and bibliographic sources, as well as on interviews with Argentine internationalists, which were methodologically conceived as life stories.
