The political history of Franco s Spain was characterized by paradoxes and contradictions. Its Foreign Policy was one of the major and perhaps the most remarkable of these paradoxes, because it points out to commitments which contradict the ideology of Franco s regime and its internal politics. This was the case of the relationship between Franco s Spain and Cuba under Fidel Castro. This work seeks to explain this special relationship opposing two variables, one from cultural and identity nature, and the other from economic kind. Finally, it tries to demonstrate that the most appropriate explanation is the one that combines both variables.
