«Trojan horse» in socialist «camp»: the Soviet Union and Yugoslavia in 1957-1958

The article considers the conflict between the Soviet Union and Yugoslavia in 1957-1958 caused by different understanding of the principles of relations between socialist states by the Soviet and Yugoslav leaderships. The Soviet Union failed to force Yugoslavia to join the Soviet bloc due to Yugoslavia's position outside the bloc and search for its own way in organizing the social regime. Yugoslavia's split with the Soviets meant a political and economic blockade and severe anti-Yugoslav campaign.
