In 2019 the Austrian government passed a law forbidding the display of Ustaše symbols, along with previously banned Nazi symbols, largely as a result of the display of same by Croatian nationalists at the annual, Croatian government-sponsored Bleiburg commemorations, where Austrian police have repeatedly arrested Croat nationalists for Nazi and fascist salutes. Three Austrian EU parliamentarians declared the Bleiburg ceremony, which tens-of-thousands of Croat nationalist attend, "the largest fascist gathering in Europe" The Austrian Catholic Church banned a Mass by the Croatian Catholic Church at Bleiburg because, as they stated, "the Mass at Bleiburg has become part of a manifestation that is politically instrumentalised and is part of a political-national ritual that serves to selectively experience and interpret history", adding that it misuses "a religious service for political purposes while not distancing itself from the Fascist worldview."
