The Liberation Front of the Slovenian People, established 26 April 1941 in Ljubljana as Anti-Imperialist Front, was the political organization of the Slovenian resistance to Axis occupation during World War II. The founding members were the Communist party of Slovenia, the Slovenian Christian Socialists, the Slovenian Sokol and a group of cultural workers. The Liberation Front proclaimed as its goals the liberation from fascism, unification of all Slovenians inside Yugoslavia, and establishment of a fairer society than the one that had existed in the Kingdom of Yugoslavia. It organized a partisan army together with other Yugoslav partisans. After 1942, the Allies fought a guerilla war against the Axis and local Quisling forces.
In September 1941, the Front's Supreme Plenum proclaimed itself Slovenian National Liberation Committee, the supreme political authority of the new Slovenia. In territories liberated by the partisan army, the Front organized local government in the form of National Liberation Committees, which organized education, cultural life, health services, and supplies for the partisan army, etc. In early 1943 the founding members made the Dolomite statement, which formally establish the Communist Party, which had been the major force in the Front since its formation, as the leading faction and disorganised the other parties.
After the capitulation of Italy in September 1943, elections were held for a meeting of National Representatives, which elected the new 120-member Supreme Plenum and 10-member Executive of the Front. This also acted as the Slovenian National Liberation Committee and the Committee's Presidency. In February 1944 in Črnomelj, the Liberation Front established the Slovenian National Liberation Council, an elected regular legislature, with departments, committees and institutes. On 5 May 1945 in Ajdovščina, the Council proclaimed the National Government Act and appointed the new national government, which moved to liberated Ljubljana on 10 May.
After the war, the Liberation Front was transformed into the Socialist Union of Working People.
