The contribution focuses on the ideological-political profile of the political Catholicism leadership in Slovenia – which strived for a corporatist society, organised on the basis of papal encyclicals and Catholic teachings – on the eve of the invasion of the Kingdom of Yugoslavia by the Axis Powers. The old corporatist concepts from “the golden age of the medieval era” represented the model for these endeavours. The Catholic ideologues, however, did not have a clear idea of how to realise these concepts in practice. Furthermore, the political regime in Slovenia was determined by the regime of the wider Yugoslav state. In such circumstances, the unrelenting anti-communism in Slovenia between both world wars was used especially as an instrument which was supposed to assist the Catholic camp with the recatholicisation of the Slovenian society. The social concept, defended by the Catholic hierarchy in Slovenia, was nevertheless entirely compatible with Hitler’s totalitarian and racist “new order”. As such it was related to the destiny of the Axis Powers in the war and thus lost its entire legitimacy in the democratic European social reality after 1945.
