In time, part of western Illyria, and to the north, Noricum and Rhaetia, came under the jurisdiction of Aquileia. Roman cities like Verona, Trent, Pola, Belluno, Feltre, Vicenza, Treviso and Padua were among its suffragans in the 5th and 6th centuries. As metropolitans of such an extensive territory, and representatives of Roman civilization among the Ostrogoths and Lombards, the archbishops of Aquileia sought and obtained from their barbarian masters the honorific title of patriarch, personal, however, as yet to each titular of the see. This title aided in promoting and at the same time justifying the strong tendency towards independence that was quite manifest in the relations of Aquileia with Rome, a trait it shared with its rival, Ravenna, which, less fortunate, never obtained the patriarchal dignity.
