Why did the Ottoman authorities suppress the Albanian League in 1881?

The Ottoman authorities suppressed the Albanian League in 1881 primarily because the sultan’s government became increasingly alarmed by the organization's strong nationalistic orientation.1

While the league was initially supported by the Ottoman Turks to help influence the Congress of Berlin, the relationship soured as the league’s objectives evolved. The Ottoman authorities grew annoyed and concerned by the league's persistent demands for political autonomy, specifically its goal to unify all Albanian territories—then divided among four provinces—into a single autonomous state within the framework of the Ottoman Empire.21

By 1881, the league's military actions and its growing influence as a symbol of national awakening prompted the Ottoman government to send an army into Albania to crush the movement.21
