Totalitarianism is a political regime in which citizens constitute a single bloc in the service of the state, through a single party. Totalitarian regimes were fascist, national-socialist and, of course, communist. Totalitarian movements aimed to organize masses rather than social classes, such as the old European parties. While political groups depended on a relative force, totalitarian movements are closely linked to the crowd's force. The main development factors of right-wing totalitarianism in Romania between the two world wars are closely linked to: the reaction to left-wing totalitarianism; national minorities; the deficiencies of Romanian democracy; intergenerational conflict. The defects, boundaries and weaknesses of Romanian inter-war democracy also contributed to the development of the right-wing totalitarianism. In the first years after the Great Union, a number of politicians, in opposition to the liberals who dominated the political scene, began to accredit the idea that the Romanian democratic system is a fake, unviable and corrupt one. On this background, the far right said that democracy itself contributes to the ruin of the nation through the "unitary bloc of Jewish power." In such a context, the punishment of the "culprits" took the form of actions with a terrorist carter. In this paper we will highlight the features of totalitarian regimes, as well as the practices that have been contributed to the development of the Iron Guard in Romania.
