Old Catholic Church of Croatia

[5] The Old Catholic Church of Croatia was created after First World War and was recognized by state authorities of Kingdom of Serbs, Croats and Slovenes (Yugoslavia) in 1923.

During Second World War, the Old Catholic Church of Croatia was banned by the Ustaše regime.

Among executed Old-Catholic clerics were: Ante Donković, Davorin Ivanović, Josip Ivelić, Ivan Cigula and Luka Malinarić.

[6] The church also suffered from several internal divisions (since 1933), and for a long time it was split in two groups that were finally united in 1974.

[7] In spite of that, the church never recovered fully, and it was placed by the Union of Utrecht under a delegated administration of Bishop Nikolaus Hummel of the Old Catholic Church of Austria (1975–1994),[8] and his successors.
