My chapter begins with an examination of the situation in Slovakia during World War II, paying particular attention to the character of the regime and its policies with regard to those termed "internal enemies," the Jews, Czechs and political opponents (especially former communists). In what follows, I introduce the Slovak prisoners of the Mauthausen camp, and traces their routes to the case by following the biographies of Otto Wagner, Pavel Branko and Ján Šagát, who were all born in Slovakia in the early 1920s.
