In the eyes of the European public, Slovenia is still considered a Catholic country. Since before the last World War, this has had a double meaning. First of all, the Roman Catholic Church has been the leading ecclesiastical institution since the Christianization of the territory settled by Slovenes, decisively influencing the constitution of the cultural and political life of the Slovene nation, as well as its character. In spite of changed social conditions and its fate in the period of “real-socialist” rule from 1945 to 1990, the Church has preserved this role to the present time, although in different forms.
