Question: Who led the Partisans and was a Yugoslav communist revolutionary and statesmen?
Context: Đilasism refers to the Yugoslav communist politics of the influence of Yugoslav Communist Milovan Đilas.  Đilasism arose as a break from Titoism pursued by the Yugoslav government of Josip Broz Tito.  The word was often used as pejorative, including by Tito, while Đilas himself personally denied that such an ideology existed. The Partisan Supreme Headquarters was created in June 1941 by the Central Committee of the Yugoslav Communist Party after the German-led Axis invasion of Yugoslavia of 6 April.  Initially titled Partisan Chief Headquarters when it was created on 4 June 1941, it was renamed at the Stolice conference of 26–27 September 1941.  Its full name became the Supreme Headquarters of the People's Liberation Partisan Detachments.  From January 1942, the headquarters became the Supreme Headquarters of the People's Liberation Partisan and Volunteer Army of Yugoslavia to allow for the incorporation of "Volunteer Detachments" consisting of insurgents that were not willing to formally become Partisans, most of whom were Serb-chauvinist Chetniks.  By November 1942, this experiment had clearly failed, and it was again renamed the Supreme Headquarters of the People's Liberation Army and Partisan Detachments of Yugoslavia.  Finally, on 1 March 1945, it became the General Staff of the Yugoslav Armed Forces. Ivan "Ivo Lola" Ribar (23 April 1916 – 27 November 1943), was a Yugoslav communist politician and military leader of Croatian descent.  In the 1930s, he became one of the closest collaborators of Josip Broz Tito, leader of the Yugoslav Communist Party.  In 1936, Ribar became secretary of the Central Committee of SKOJ (Young Communist League of Yugoslavia).  During the World War II in Yugoslavia, Ribar was among the main leaders of the Yugoslav Partisans and was a member of the Partisans' Supreme Command.  During the war, he founded and run several leftist youth magazines.  In 1942, Ribar was among the founders of the Unified League of Anti-Fascist Youth of Yugoslavia (USAOJ).  He was killed by German bomb in 1943 near Glamoč while boarding an airplane for Cairo, where he was to become the first representative of Communist Yugoslavia to the Middle East Command. The German–Yugoslav Partisan negotiations were held between German commanders in the Independent State of Croatia and the Supreme Headquarters of the Yugoslav Partisans in March 1943 during World War II.  The negotiations – focused on obtaining a ceasefire and establishing a prisoner exchange – were conducted during the Axis Case White offensive.  They were used by the Partisans to delay the Axis forces while the Partisans crossed the Neretva river, and to allow the Partisans to focus on attacking their Chetnik rivals led by Draža Mihailović.  The negotiations were accompanied by an informal ceasefire that lasted about six weeks before being called off on orders from Adolf Hitler.  The short-term advantage gained by the Partisans through the negotiations was lost when the Axis Case Black offensive was launched in mid-May 1943.  Prisoner exchanges, which had been occurring between the Germans and Partisans for some months prior, re-commenced in late 1943 and continued until the end of the war. Military operations in World War II in Yugoslavia began on 6 April 1941, when the Kingdom of Yugoslavia was swiftly conquered by Axis forces and partitioned between Germany, Italy, Hungary, Bulgaria and client regimes.  Subsequently, a guerrilla liberation war was fought against the Axis occupying forces and their locally established puppet regimes, including the Independent State of Croatia and the Serbian Government of National Salvation, by the KPJ-led republican Yugoslav Partisans.  Simultaneously, a multi-side civil war was waged between the Yugoslav communist Partisans, the Serbian royalist Chetniks, Croatian fascist Ustaše and Home Guard, as well as Slovene Home Guard troops. Milan Basta (1 March 1921 – 4 December 2007) was a Yugoslav World War II general, a member of the Partisan Movement and a publicist.  He was born in 1921 in Kurjak, a village in Lika – a region in today’s Croatia.  He attended grammar school in Zagreb, Croatia where he joined the League of Communist Youth of Yugoslavia (SKOJ) in 1939.  In 1941 he became a member of the Yugoslav Communist Party.  After joining the Yugoslav Partisans, he participated actively in the preparation of the uprising against the German occupier.  During the liberation war in Yugoslavia he was appointed political commissar of the “Krbava” battalion, 2nd Lika Detachment and 3rd Lika Proletarian Brigade.  He was the head of the political department of the 20th division and 12th Vojvodina Brigade.  In 1945 he performed duty of the political commissar of the 51st Vojvodina Division which took part in the battles at the Yugoslav-Austrian border. Josip Broz (Cyrillic: Јосип Броз, ] ); 7 May 1892 – 4 May 1980), commonly known as Tito (Cyrillic: Тито, ] ), was a Yugoslav communist revolutionary and statesman, serving in various roles from 1943 until his death in 1980.  During World War II he was the leader of the Partisans, often regarded as the most effective resistance movement in occupied Europe.  While his presidency has been criticized as authoritarian, and concerns about the repression of political opponents have been raised, some historians consider him a benevolent dictator.  He was a popular public figure both in Yugoslavia and abroad.  Viewed as a unifying symbol, his internal policies maintained the peaceful coexistence of the nations of the Yugoslav federation.  He gained further international attention as the chief leader of the Non-Aligned Movement, working with Jawaharlal Nehru of India, Gamal Abdel Nasser of Egypt and Sukarno of Indonesia. Vojo Kushi (August 3, 1918 – October 10, 1942) was an Albanian and Yugoslav communist guerilla fighter (partisan) and one of the founders of the Communist group based in Shkodër, following the Italian occupation of Albania in April 1939.  He was proclaimed a National Hero of Yugoslavia by the Yugoslav communist government on February 12, 1945, and then a Hero of Albania by the Albanian communist government in 1946. Operation Hydra was a failed British attempt during World War II in Yugoslavia to develop contact with the Partisans led by Josip Broz Tito, in Montenegro in February 1942. Konstantin "Koča" Popović (; 14 March 1908 – 20 October 1992) was a Yugoslav communist volunteer in the Spanish Civil War, 1937–1939 and Divisional Commander of the First Proletarian Division of the Yugoslav Partisans.  Sometimes he was known as "the man who saved Yugoslav Partisans" because he broke through the German lines during the crucial Battle of Sutjeska and saved Tito and the rest of the resistance movement.  After the war, he served as the Chiefs of the General Staff of the Yugoslav People's Army, before moving to the position of Foreign Minister and spent the final years of his political career as the Vice President of Yugoslavia.
