Soviet empire

The term "Soviet empire" collectively refers to the world's territories that the Soviet Union dominated politically, economically, and militarily. This phenomenon, particularly in the context of the Cold War, is used by Sovietologists to describe the extent of the Soviet Union's hegemony over the Second World. In a wider sense, the term refers to Soviet foreign policy during the Cold War, which has been characterized as imperialist: the nations which were part of the "Soviet empire" were nominally independent countries with separate governments that set their own policies, but those policies had to stay within certain limits decided by the Soviet Union. These limits were enforced by the threat of intervention by Soviet forces, and later the Warsaw Pact. Major military interventions took place in East Germany in 1953, Hungary in 1956, Czechoslovakia in 1968, Poland in 1981–83 and Afghanistan from 1979 to 1989. Countries in the Eastern Bloc were Soviet satellite states.
