Ottomans authorities cancelled their assistance when the league, under Abdyl Frashëri, became focused on working toward Albanian autonomy and requested merging four vilayets, including Kosovo, Shkodër, Monastir and Ioannina, into an unified vilayet, the Albanian Vilayet. The league used military force to prevent the annexing areas of Plav and Gusinje assigned to Montenegro. After several successful battles with Montenegrin troops, such as the Battle of Novšiće, the league was forced to retreat from their contested regions. The league was later defeated by the Ottoman army sent by the sultan.
