The notion of totalitarianism began to be used after 1923 to mark a fascist movement in Italy, and it later spread to related phenomena in other countries.Totality was to be represented by authority which is not satisfied only by controlling the political life in the country, but it tries to spread its web to every pore of life, all social subsystems, from the economy, media, culture, sport, and it also reaches into the private sphere and tries to influence a person’s way of thinking, making decisions and acting.The notion of totalitarianism started being used scientifically after the 2nd World War, when the majority of Eastern Europe lived under the supervision of Stalin’s Soviet Union. Hannah Arendt published The Origins of Totalitarianism in 1951, a basis work in which she compared German Nazism and Soviet Stalinism. She placed the rise of such regimes in the circle of longer historical development and explained the principles according to which the authority in some countries could be marked as totalitarian. She emphasised that this is true mainly for Germany under Hitler and the Soviet Union under Stalin, and she warned that Mussolini’s Italy is not completely comparable with the previously mentioned regimes and that it could not be classified into the category of totalitarian authority without hesitation. In the next decades research was under the effect of the Cold War, and attention was often oriented towards comparing the Soviet Union under Stalin and after his death at the time of de-Stalinization. The question of which regimes can be marked as totalitarian continued for decades and it received more attention in professional discussions again after the fall of the Berlin Wall and the end of the Cold War in the 1990s.
