Krbava (; ) is a historical region located in Mountainous Croatia and a former Catholic bishopric (1185–1460), precursor of the diocese of Modruš and present Latin titular see. It can be considered either located east of Lika, or indeed as the eastern part of Lika. The town of Udbina is the central settlement of the Krbava karst field, the Krbavsko Polje. History Overview Krbava was one of twelve medieval regions that later comprised the later Lika-Krbava County. Numerous historical sources, mainly in Latin, referred to toponyms within Krbava, most of which have been correlated with modern-day toponymy. The most important historical event in Krbava was the Battle of Krbava Field in 1493. During Croatia in the union with Hungary, nobility were given the title "of Krbava" (de Corbauia). Ecclesiastical history Its capital Udbina became the seat of a Catholic bishopric of Corbavia (Latin = Curiate Italian) / Corbavien(sis) (Latin adjective) when the council of Split (Spalato) in 1185 detached a new suffragan see from the Archdiocese of Spalato (which became its Metropolitan). It comprised the county of Corbavia, part of the county of Lika and the territories of Modruš, Novigrad and Vinodol (Novi Vinodolski, Italian Novi in Valdivino), south-east of Fiume. Pope Urban III approved the erection and the nomination as first bishop of Matteo with the synodal acts. During the 1460s, due to the Ottoman (Turkish) advance in Dalmatia, the diocese of Corbavia was formally suppressed by Pope Pius II, but its territory immediately reassigned to establish as successor see the Diocese of Modruš (Croatian = Curiate Italian) / Modrussa / Modrussen(sis) (Latin), named after its new see, near Fiume (Rijeka), at the rock fortress of the Frankopan counts (now in the comune Josipdol). Again it was a suffragan of the Metropolitan Archdiocese of Spalato (Split).
