Albanian intervention occurred when after the Congress of Berlin in 1878, parts of Chameria, were to be ceded by the Ottoman Empire to the Kingdom of Greece. Even before negotiations started, the Ottoman side used a number of Albanian national figures for delaying purposes and appointed Abedin bey Dino, as Ottoman foreign minister. Moreover, Abedin Dino managed to gather various Albanian personalities in Preveza, from all over Albania and Epirus, who believed that the Ottomans will provide full support to the Albanian movement and were against annexation of Epirus to Greece. They also organized a meeting there in January 1879 and on 28 February 1879, signed a petition with a threat to take arms to prevent an annexation of Preveza to Greece. As a result of the unrest created, led by Abdyl Frashëri, another Albanian national figure, the local Ottoman governor was recalled. Abedin Dino was also recalled from Preveza, while the recently arrived Albanians left the city and returned to their homelands.
