Edvard Kardelj (pronounced [ˈéːdʋaɾt kaɾˈdéːl]; 27 January 1910 – 10 February 1979), also known under the pseudonyms Bevc, Sperans and Krištof, was a journalist from Ljubljana, Slovenia, and one of the leading members of the illegal Communist Party of Slovenia before World War II. During the war he was one of the leaders of the Liberation Front of the Slovenian People and a Slovene Partisan, and after the war a federal political leader in socialist Yugoslavia who led the Yugoslav delegation that negotiated peace talks with Italy over the border dispute in the Julian March. He is considered the main creator of the Yugoslav system of workers' self-management. He was an economist and a full member of both the Slovene Academy of Sciences and Arts and Serbian Academy of Sciences and Arts.
Kardelj was born in Ljubljana. At the age of 16 he joined the Communist Party of Yugoslavia, where he was drafted under the influence of the Slovenian journalist Vlado Kozak. He studied to become a teacher but never worked as one. In 1930, he was arrested in Belgrade and convicted of being a member of the illegal Communist Party. He was released in 1932 and returned to Ljubljana, where he became one of the leaders of the Slovenian section of the party after most of its former members had either left the party or perished in Joseph Stalin's purges.
