After a few unsuccessful Ottoman attacks at the beginning of the 16th century, apart from minor frictions and looting at the border, there were no major conflicts in Croatia and Hungary.
Unlike raids in the previous years, these actions constituted a war campaign of a wider scale to establish the means for further conquests of Croatia.
Berislavić fully pledged to stop the Ottoman invasion and defend the Croatian border on the line from Srijem, through Bosnia and Jajce, to Veliki Prolog in Dalmatia.
Centralist reforms of King Matthias Corvinus were abolished, and the nobility reestablished their old privileges, gaining tax and war subsidy exemptions.
On 13 June 1513, during the Fifth Council of the Lateran, bishop of Modruš Simon Kožičić Benja also presented the difficult position of Croatia which was under constant Ottoman attacks.
[7] Ottoman forces, led by sanjak-bey Junuz-aga,[8] entered the area between Una and Kupa rivers in early summer 1513 with 7,000 cavalrymen and attacked Blinja near Petrinja.
Berislavić was awarded a blessed sword from Pope Leo X on 25 December 1513, while King Vladislaus named him Count of Dubica and Prior of Vrana.
[9] Berislavić spent seven years in constant fighting with the Ottomans, faced with continuous money shortages and an insufficient number of troops until he was killed in an ambush during the battle of Plješevica on 20 May 1520.
