The league was established at the meeting of 47 Ottoman beys. An initial position of the league was presented in the document known as Kararname. With this document, Albanian leaders emphasized their intention to preserve and maintain the territorial integrity of the Ottoman Empire in the Balkans by supporting the porte, and "to struggle in arms to defend the wholeness of the territories of Albania". Although it said nothing about the reforms, schools, autonomy or about the union of the Albanian population within one vilayet, under influence of Abdyl Frashëri, this initial position has changed radically and resulted in demands of autonomy of Albanians and open war against the Ottoman Empire.

The Prizren Castle contains in itself an important part of the ancient history of the city.

It is located in the eastern part of the city, over a conical-shaped hill.
