Yugoslav-Soviet relations, Czechoslovakia, USSR, Yugoslavia, the "Prague Spring", the doctrine of limited sovereignty, military intervention, reform socialism, 1968, Josip Broz Tito
The Soviet-Yugoslav relations oscillated in the postwar period from the divergence and conflict to the cooperation and understanding, and the researchers identified three major crisis between Moscow and Belgrade. The first escalation of hostilities took place in the turning 1948, after the IB Resolution, which resulted in the complete disruption of relations between the two countries. The cause of the second crisis was the draft of the LCY (SKJ), which was prepared for adoption at the VII Congress in 1958, and which was assessed in the Soviet Union as revisionist, anti-Marxist, demanding to withdraw from it. Finally, the third serious antagonism of Yugoslav-Soviet relations was initiated by the aggression against Czechoslovakia, which was performed by the USSR and its East European satellites, as well as by the sharp Yugoslav reaction to the act of breaching the international law and military trampling of a sovereign state.
