The League of Communists of Yugoslavia was the ruling political party in the former Socialist Federal Republic of Yugoslavia from its formation in 1952 until the early 1990s. It emerged from the anti-fascist movement during World War II and was led by prominent figures like Josip Broz Tito. The party aimed to establish a socialist society based on self-management and worker participation. The League played a crucial role in the country's governance, promoting a unique form of socialism that differed from the Soviet model. However, internal divisions and rising nationalism contributed to its decline, leading to the breakup of Yugoslavia and the eventual dissolution of the party in 1990.
