No nation lives in a vacuum. The Spanish Civil War of1936-39 was a product of the admixture of converging indigenous tensions and the plight of the broader civilization of which the Spanish people form a part. The maritime war remained throughout the Spanish conflict the result of just such a confluence of Spanish and foreign decisions, forces, and actions. This combination was a crucial element in the course and outcome of the Spanish war and an integral factor in Europe's downslide toward the Second World War.
