By the end of the Second World War, the main military and political force of the nation, the Communist party sent forces to northern Albania against the nationalists to eliminate its rivals. They faced open resistance in Nikaj-Mërtur, Dukagjin and Kelmend led by Prek Cali. On 15 January 1945, a clash took place between partisans of the first Brigade and nationalist forces at the Tamara Bridge, resulting in the defeat of the nationalist forces. About 150 Kelmendi people were killed or tortured. This event was the starting point of many other issues which took place during Enver Hoxha's dictatorship. Class struggle was strictly applied, human freedom and human rights were denied. The Kelmend region was almost isolated by both the border and by a lack of roads for another 20 years, the institution of agricultural cooperatives brought about economic decline. Many Kelmendi people fled, and some were executed trying to cross the border.
