League of Prizren is established, to oppose the decisions of the Congress of Berlin and the Treaty of San Stefano, as a consequence of which the Albanian lands in the Balkans were being partitioned and given to the neighbor states of Serbia, Montenegro, Bulgaria, and Greece.

The League of Prizren was founded on June 10, 1878, to unite Albanian leaders against the territorial partitioning by the Congress of Berlin and the Treaty of San Stefano.
On June 10, 1878, delegates from various Albanian regions met in Prizren to form the League of Prizren, aiming to defend Albanian-inhabited lands against division by neighboring states. The league opposed the decisions of the Congress of Berlin and the Treaty of San Stefano, which threatened to allocate Albanian territories to Serbia, Montenegro, Bulgaria, and Greece. Under the leadership of figures like Abdyl Frashëri, the organization sought autonomy within the Ottoman Empire, the promotion of Albanian-language schools, and administrative reforms. While lacking a formal army, the league organized local militias to protect communities and assert political demands. It employed diplomatic channels in Istanbul and European capitals to argue its cause. Although suppressed by Ottoman authorities in 1881, the League of Prizren served as a foundation for Albanian national identity and future independence movements. Its legacy endures as a symbol of unity and resistance in Albanian history.
