After the fall of the Bosnian Kingdom into Ottoman hands in 1463, the southern and central parts of the Kingdom of Croatia remained unprotected, the defense of which was left to the Croatian gentry who kept smaller troops in the fortified border areas at their own expense. The Ottomans meanwhile reached the river Neretva and having conquered Herzegovina in 1482, they found their way toward Croatia, skillfully avoiding the fortified border towns. Through the conquest of the Kingdom of Croatia, the Ottoman light cavalry pushed its way towards the towns of Carinthia and Carniola, threatening thus to a border area of Venice as well.
