The following dioceses were situated in Süd-Tirol / Trentino-Alto Adige, that part of Austria that was ceded to Italy after World War I: Trient (1929: Trento AD, 1964: Trento [Metr.]), Säben, and Brixen (1964: Bozen-Brixen / Bolzano-Bressanone).
All the territory of Lavant has been outside Austria since 1923 (is now in Slovenia), and the diocese was renamed Maribor in 1962.
