Abstract: Sighet, a town situated in the northern extremity of Romania, has fully experienced the horrors of the two totalitarianisms of the 20th century: Nazism and Communism. In the spring of 1944, in Sighet, town with a numerous Jewish community, under the Hungarian administration since 1940, two ghettos were set up, in which were gathered around 12,000 Jews from the town and from the neighborhood. After a few weeks, the Jews from Sighet were deported in the Nazi extermination camps. At the beginning of the 50?s, a part of the former inter-war Romanian political elite  were  imprisoned in the Sighet penitentiary, who were seen by the communist authorities more as  potential adversaries, rather than opponents in the true sense of the term. They were joined by catholic bishops and priests, arrested for refusing the conversion to orthodoxy. The goal of this study is to present, with the help of the archives and of the proper bibliography, certain aspects of the general context in which the events mentioned above took place, the means of organization and functioning of these structures, as well as the institutions and the persons involved.
