The Velika Kladuša Castle is first mentioned in historical sources in 1280 under King Ladislaus IV of Hungary.

The castle boasted great strategic importance for the Ottoman conquests towards Croatia.

They sent out a declaration form or royal firman (mandate or decree) to the dizdar of the castle.

The last Dizdar (castle captain) of Velika Kladuša was Husein Alagić, whose family served in the same position for the prior 150 years.

The troops of the general of Karlovac defeated the army of the captain Murad Beširević.

The battle raged in the city of Velika Kladuša for ten days between one battalion of the attacking Austro-Hungarian army.
