Croatia in personal union with Hungary The castle was first mentioned in 1364 in medieval documents as the name of a land district. Built from the
cut stone, it was an important
stronghold of Croatian troops during the
Wars of Ottoman expansion in the 15th century. At the time of the Battle of Krbava, it was owned by Croatian Kurjaković noble family, a.k.a.
dukes of
Krbava (Corbavia). Before the battle itself, Karlo Kurjaković, a distinguished Croatian nobleman, who possessed a large part of
Lika, including Udbina, suddenly died, leaving his wife Dorotea Kurjaković née
Frankopan and his little son,
Ivan (* 1485; † 1531), future
ban (Viceroy) of Croatia (who ruled 1521–1524 and 1527–1531) and the last male member of the Kurjaković family, in the castle. Both of them observed the course of the battle in the field below, without interfering. The castle wasn't involved in the battle at all, since the winning Ottoman akinjis left further for
Bosnia, taking
captives and
loot along.
Ottoman Empire Despite the Croatian defeat in 1493, it was only in 1527 that the castle fell into Ottoman hands and became their stronghold in the region. They expanded and enhanced the fortifications, making them harder to capture. However, Ottomans were routed from Udbina during the Great Turkish War in 1689, after
Habsburg-Croatian army besieged the castle (following the lack of water in it, which led Turks to surrender).
Habsburg Monarchy The Ottoman forces then withdrew back to Bosnia in 1689 and the whole area, including the Udbina Castle, became part of the
Croatian Military Frontier. During the course of 19th century it was left for a slow and continuing ruination. ==Architecture==
