During the reign of Demetrius Zvonimir (1075–1089), the mythical golden age of the Kingdom of Croatia, the highest court offices of  (comes camerarius) and  (comes palatinus) were held by Budez and Dominicus, both of the lineage. During the 13th and 14th centuries Brebers were many times called to cover the post of count in the townships of Split, Trogir, Skradin and Omiš, primarily clashing with Domald of Sidraga, Kačić and Nelipić family. In the documents, it is possible to identify six different branches of the Breber clan. The most illustrious of which is the one descended from iupanus Miroslaus Brebriensis, filius Bogdanizi (1184). His great-grandson Paul, mentioned above, reached the peak of power towards the end of the 13th century. He was Ban of Croatia and Dalmatia, his rule extended to Bosnia, and with his brothers he controlled the maritime cities of Dalmatia. In these regions he was champion of the Pope and was instrumental in placing Charles, the firstborn of the King of Naples, on the throne of Hungary and Croatia. He was related to the King of Naples, the King of Serbia, the Da Camino lords of Treviso, and the Tiepolo and Dandolo patricians of Venice. When he died in 1312, his eldest son Mladen tried to maintain the hold over the other Croatian clans, but was unsuccessful and bit by bit lost land, castles and towns.
