The activities of Croatian and Slovenian societies and associations (Sokol, reading rooms, etc.) had already been forbidden during the occupation, but specifically so later with the Law on Associations (1925), the Law on Public Demonstrations (1926) and the Law on Public Order (1926).
Helped by the Ustaše, a Croatian fascist movement animated by Catholicism and ultranationalism, the Italian occupation continued its repression of Partisan activities and the killing and imprisonment of thousands of Yugoslav civilians in concentration camps (such as the Rab concentration camp) in the newly annexed provinces.
