The Gusić family, also known as Gušić, was one of the twelve noble tribes of the Kingdom of Croatia, mentioned in the Pacta conventa. They originated from the hinterland of Biograd in the medieval Luka and Sidraga županijas, where they are recorded at least since the 11th century. Their main regions of influence were Krbava and Gacka, where they often served as župans and knezes at least since the early 13th century. In the 14th century branched Posedarski who seated in Posedarje, and Kurjakovići who as magnates managed to gather much wealth and have high official positions at the Hungarian royal court as well two of their members became Ban of Croatia. As experienced warriors, they actively participated in the Croatian–Ottoman and late Ottoman–Venetian Wars. Direct descendants of the tribe with the surname Gusić, and possibly Gušić, live even today in Croatia and Slovenia.

The Smiljanić family (Smogianich) were a Vlach/Morlach family originating from Lika and first mentioned in the 17th century, when the oldest member Petar Smiljanić was a harambaša and capo (head) of the Morlach troops in Venetian service during the Cretan War (1645–69), in Venetian Dalmatia. He was born in Udbina, in the Lika region, then moved with his family to Venetian Dalmatia in 1647. From the family originated nine serdars, who participated in the Cretan War (1645–69) and Morean War (1684–1699). The family and its members are also perceived as Croatian, and Serbian in national historiographies.
