How and why did the Soviet Union get involved in WWII?
The Soviet Union’s involvement in World War II is a complex narrative marked by strategic, ideological, and geopolitical motivations.
The Soviet entry into the war was not immediate but evolved through various phases, starting from cautious neutrality and shifting to active participation following a direct attack by Nazi Germany.
This extensive involvement was instrumental in shaping the course of the war and had profound implications for global politics in the decades that followed.
Pre-War Period and the Molotov-Ribbentrop Pact
Before the outbreak of World War II, the Soviet Union was primarily concerned with its own security and territorial interests. The rise of Nazi Germany posed a significant threat, especially after Adolf Hitler made clear his aggressive intentions towards Eastern Europe.
The Soviets were initially part of negotiations with Britain and France to form a potential alliance against Germany, but these talks faltered over mutual distrust and strategic disagreements.
In a surprising turn of events, in August 1939, the Soviet Union signed the Molotov-Ribbentrop Pact with Nazi Germany. This non-aggression treaty included secret protocols that divided Eastern Europe into German and Soviet spheres of influence, effectively allowing the Soviet Union to secure its western borders and assert control over the Baltic states and parts of Romania and Poland. This pact was primarily a strategic maneuver by Stalin to avoid a two-front war while the Soviet military was still underprepared.

The Winter War with Finland
Shortly after the pact, the Soviet Union sought to secure its northern borders by demanding territorial concessions from Finland. When negotiations failed, the Soviets invaded Finland in November 1939, initiating the Winter War.
The conflict proved costly and embarrassing for the Soviet military, which struggled against Finnish resistance. The war ended in March 1940 with the Moscow Peace Treaty, where Finland ceded some territories but preserved its independence. This conflict, however, exposed weaknesses in the Soviet military and led to significant reforms and purges within the Soviet armed forces.
Occupation of the Baltic States and Eastern Poland
Taking advantage of the Molotov-Ribbentrop Pact, the Soviet Union also occupied Eastern Poland in September 1939, following Germany’s invasion from the west. This occupation was justified by the Soviets as a means to protect Belarusians and Ukrainians from the chaos of the Polish collapse.
In 1940, the Soviet Union further extended its influence by annexing the Baltic states (Estonia, Latvia, and Lithuania) and parts of Romania (Bessarabia and Northern Bukovina), again citing security reasons and the protection of local Slavic populations.

The Turn of the Tide: Operation Barbarossa
The fragile peace between Nazi Germany and the Soviet Union came to an abrupt end on June 22, 1941, when Germany launched Operation Barbarossa, a massive invasion of the Soviet Union that caught Stalin and his military largely unprepared. The scale and ferocity of the attack were unprecedented, with millions of German troops advancing along a broad front from the Baltic Sea to the Black Sea.
The initial months of the invasion were devastating for the Soviets, with significant territories quickly overrun and the Wehrmacht approaching Moscow.
However, the harsh Russian winter and overstretched German supply lines, coupled with fierce Soviet resistance and strategic counter-offensives like those at Stalingrad and Kursk, gradually turned the tide in favor of the Allies.
Soviet Role in the Allied Victory and Beyond
The Soviet Union’s involvement in WWII became one of the critical elements leading to the defeat of Nazi Germany. The Eastern Front was the largest and bloodiest theater of war, inflicting substantial casualties on the German military. Soviet forces eventually pushed through Eastern Europe and captured Berlin in May 1945, a pivotal moment that marked the end of the war in Europe.
Post-war, the Soviet Union emerged as a superpower, its role in the war having significantly expanded its influence across Eastern Europe. This expansion set the stage for the Cold War, a period of geopolitical tension between the Soviet Bloc and the Western Bloc that lasted until the dissolution of the Soviet Union in 1991.
World War II not only reshaped the Soviet Union’s military and domestic policies but also its international standing, deeply influencing global political dynamics for much of the 20th century. Image: A 1939 image showing troops of the Soviet Union on parade in Lwów, Ukraine.
