Titoism is described as the post-World War II policies and practices associated with Josip Broz Tito during the Cold War, characterized by an opposition to the Soviet Union. It usually represents Josip Broz Tito's Yugoslav doctrine in Cold War international politics. It emerged with the Yugoslav Partisans' liberation of Yugoslavia independently of, or without much help from, the Red Army, resulting in Yugoslavia being the only Eastern European country to remain "socialist, but independent" after World War II as well as resisting Soviet Union pressure to become a member of the Warsaw Pact. The term was originally used by the government of the Soviet Union to denote it as a heresy. Today it is used to refer to Yugo-nostalgia.
