The Battle of Una (Croatian: Bitka na Uni) was fought on 29 and 30 October 1483 between the regional Ottoman forces, mostly from the Sanjak of Bosnia, and the Kingdom of Croatia near Brod Zrinski (modern-day Novi Grad in Bosnia and Herzegovina) at the Una River crossing and was one of the first major Croatian victories against the Ottoman Empire. The Croatian army was led by the Ban of Croatia Matthias Geréb and several members of the House of Frankopan, joined by other Croatian nobles and the Despot of Serbia, Vuk Grgurević. Their goal was to intercept the Ottomans that were moving towards the Una River. In the battle that lasted for 2 days the Ottomans were defeated and soon a 7-year truce was signed with Sultan Bayezid II.

Following the fall of Počitelj on the Neretva River in 1471, the whole land between Cetina and Neretva rivers except the coastline fell into Ottoman hands. To prevent further Ottoman expansion, King Matthias Corvinus named Nicholas of Ilok titular King of Bosnia. The Kingdom of Bosnia was conquered by the Ottomans in 1463 and their last king Stephen Tomašević was beheaded by Mehmed II. Soon Nicholas of Ilok was named Ban of Croatia and Slavonia, making them a single administrative unit. His task was to take the parts of Bosnia that were still held by the Ottomans, but he failed to do so. Following his death King Matthias broke into Bosnia and reached Sarajevo, however, his success was temporary. In 1482 the Ottomans conquered Herzegovina. That same year Ottoman forces from the Sanjak of Bosnia plundered Carniola, while in 1483 they ravaged the surroundings of Ptuj in southern Styria.
