Following Fulgencio Batista’s 1952 military coup, Auténticos tapped into this near-decade-long transnational networking to support their own opposition against their own dictator. Departing from the scholarly focus on Fidel Castro, this paper finds that numerous Cuban exiles traveled the Caribbean Basin to lobby for allies, collect resources, and organize plots against Batista’s regime. Thanks to never-before-utilized Cuban military and intelligence reports with newly-declassified Dominican, Mexican, and British files and exiles’ personal collections, this paper recovers the overlooked contributions of an entire regional ‘front’ of Cubans who worked with Caribbean Basin exiles and leaders, U.S. organizations, and Costa Rican and Venezuelan presidents to challenge Batista while contributing to and challenging Castro’s own movement.
