In 1455, the southern territories of the Serbian Despotate were annexed by the Ottomans, and organized into the beylerbeylik of Rumelia. Gora, in its broadest meaning, became a nahiyah of the Sanjak of Prizren. The Ottoman conquest resulted in the old trade routes that linked the Adriatic to the Aegean and Black sea lost their importance because of the insecurity on the roads, and the towns and villages along the roads stopped growing. There are no sources which name Opolje a nahiya in the 15th century.
