Formation of a Soviet Bloc (AQA A-Level History): Revision Notes
Formation of a Soviet Bloc
The conclusion of the Second World War established Soviet military control across eastern and central Europe. This occupation provided the foundation for constructing a Soviet bloc (also termed the "Soviet Empire"). The USSR expanded its territorial boundaries and exploited its military presence alongside political leverage over local communist parties to install governments sympathetic to Soviet interests. By 1948, the majority of these nations had become closely aligned with the USSR as satellite states.
Understanding key terms
Satellite states were countries that maintained their national identity while operating under pro-Soviet governments. These regimes, sometimes labelled "puppet states", fell progressively under Soviet control from 1949 onwards.
Buffer states described those satellite states of Eastern Europe which Stalin intended to function as a protective barrier for the USSR's western frontiers, creating a zone that would shield against future invasion from the west.
Soviet territorial expansion after 1945
The map of post-war Europe underwent substantial reconfiguration. The USSR directly absorbed several territories:
- Estonia, Latvia, and Lithuania (the Baltic States)
- Eastern Poland (including areas around Kaliningrad Oblast)
- Belarus and Ukraine (expanded territories)
- Moldova (formerly Romanian territory)
Beyond direct annexation, neighbouring states transformed into Soviet spheres of influence:
- Poland
- Czechoslovakia
- Hungary
- Romania
- Bulgaria
- Albania
- East Germany (Soviet zone of occupation)
This strategic arrangement created Stalin's desired buffer zone, intended to prevent future western invasion and provide a defensive perimeter around Soviet borders.
Origins of Soviet expansion: the Nazi-Soviet Pact
The Soviet bloc's foundations predated the war's end. Under the Nazi-Soviet Pact of 1939, the USSR invaded and occupied eastern Poland. In 1940, secret protocols within this pact enabled Soviet forces to occupy the Baltic States. These annexations formed part of a long-term strategy, implemented without mercy.
Stalin's methods for establishing Soviet control were characterized by systematic brutality aimed at eliminating any nationalist opposition that could challenge communist authority. Two events particularly exemplify this ruthless approach: the Katyn Forest Massacre and the Warsaw Uprising.
The Katyn Forest Massacre
Historical Case: The Katyn Forest Massacre (1940)
Between April and May 1940, approximately 22,000 captured Polish army officers were executed by the NKVD. This massacre aimed to eliminate Polish nationalist elements who might challenge communist authority.
The Cover-Up: Soviet forces 'discovered' the mass graves at Katyn Forest near Smolensk in 1943, subsequently attributing the atrocity to the Nazis. This fabrication persisted as official communist Poland policy until the 1980s. Under Gorbachev's administration, the USSR finally acknowledged responsibility in 1990, expressing regret.
The same brutal approach continued in 1944 when the Red Army was instructed to halt its advance, permitting the Nazis time to suppress the Warsaw Uprising.
The Warsaw Uprising
On 1 August 1944, as the Red Army approached Warsaw, Polish resistance fighters from the AK (Home Army) launched an uprising to liberate their city from German occupation and establish an independent Polish Underground State. Soviet forces halted their advance east of the Vistula River, providing no assistance to the insurgents. The AK fought for over 60 days before the uprising was suppressed. Warsaw suffered devastating destruction.
Subsequently, claims emerged about "operational difficulties" explaining the Red Army's inaction, but the underlying motives were overwhelmingly political. Allowing the Nazis to destroy the non-communist resistance removed obstacles to Soviet-controlled government installation.
Installing communist governments: methods and stages
From the 1930s, exiled communist party groups from various European countries had received training in Moscow, preparing to infiltrate post-liberation governments. When the Red Army entered Poland, a provisional government dominated by pro-Moscow communists was established at Lublin. In Yugoslavia, communist partisans led by Josip Tito seized control of the post-war government. Tito's regime became an essential component of the Soviet bloc. Communist regimes also controlled Bulgaria and Romania. The eastern region of Germany became a Soviet occupation zone, with Moscow-trained Communists achieving political dominance by 1946.
Establishing Soviet control in east central Europe required more gradual approaches in countries where democratic national governments had been elected. Moscow instructed local communist parties to form coalitions with non-communists and "bourgeois liberals", creating a political foothold that could be slowly expanded.
Salami tactics
This infiltration strategy, dubbed "salami tactics", enabled pro-Soviet governments to consolidate power incrementally. The Hungarian communist leader Miklos Rakosi coined this term to explain the method of subverting bourgeois parties and gaining control from within through small steps.
Historical Application: Salami Tactics in Practice
The strategy worked through multiple approaches:
- Quiet infiltration of trade unions, journalism, and local government structures
- Targeted harassment or violence against opposition figures
- Systematic elimination of political opponents
Key Cases:
- Hungary (1947): Communist parties eliminated opposition despite initially sharing power in coalition governments
- Czechoslovakia (1948): In a dramatic example, anti-Soviet foreign minister Jan Masaryk died falling from a high window in Prague. Evidence suggested the communists had eliminated him.
American historian Robert Tucker described salami tactics as integral to Stalin's overarching strategy for pushing communism into Europe's heartland.
The progressive expansion of Soviet influence generated mounting diplomatic tensions and anxieties about potential open conflict between the USSR and the capitalist West.
Remember!
Key Points to Remember:
- The Soviet bloc formed through military occupation followed by political manipulation, creating satellite states that functioned as buffer states protecting the USSR's western borders.
- By 1948, most eastern and central European countries had fallen under Soviet control through direct annexation (Baltic States, eastern Poland) or puppet governments (Poland, Czechoslovakia, Hungary, Romania, Bulgaria, Albania).
- Stalin employed ruthless methods to eliminate nationalist opposition, exemplified by the Katyn Forest Massacre (1940) and deliberately allowing the Warsaw Uprising to fail (1944).
- "Salami tactics" described the gradual communist infiltration strategy, whereby pro-Soviet parties formed coalitions before systematically removing opposition through infiltration, harassment, and violence.
