The book presents various investigation into 20th-century European dictatorships, with its focus on Franco`s dictatorship and the Spanish Civil War. Francisco Franco’s dictatorship in Spain (1936/1939-1975/1978) was a modern form of authoritarianism, with a strong totalitarian period, like many other dictatorships of the time. Francoism occupies a place in history alongside other different dictatorships of its age, and a comparative analysis might prove to be a powerful tool in order to understand how, in the middle of the 20th century, such a repressive and authoritarian form of political control emerged. One of the most forgotten fascisms, which at the same time was influenced by and influenced other dictatorships, there are many aspects of the transnational connections of Francoism that remain under-researched. Following this methodology, thus, an attempt is made to situate Francoism in the context of the other dictatorships of the time, in an attempt to transcend explanations centered on the nation. The chapters cover groundbreaking topics such as the Spanish Civil War as one of the first total wars or Spanish fascism in context as one of the main European totalitarianisms. The chapters always have more than one dimension: they speak of interrelation, entanglement, collaboration and diffusion, and, in general, put the different dictatorships (essentially: Francoism, diverse Fascisms and Communism) in context and comparison.
