3.1 The Nazi-Soviet Non-Aggression Pact and the Outbreak of World War II

The Nazi-Soviet Non-Aggression Pact of 1939 was a game-changer in European politics. It allowed Germany to avoid a two-front war and gave the Soviet Union time to expand. This unexpected alliance shocked the world and set the stage for World War II.

The pact had far-reaching consequences. It left smaller Eastern European nations vulnerable and neutralized potential alliances against Germany. The Soviet Union's subsequent invasions of neighboring countries escalated tensions and contributed to the global conflict.

1 of 3

• Germany sought to avoid a two-front war by securing its eastern border before initiating a campaign against Poland and Western Europe
• The pact allowed Germany to focus its military efforts on the western front without immediate threat from the Soviet Union
• Germany aimed to prevent the formation of a joint Anglo-French-Soviet alliance that could hinder its expansionist goals
• The pact provided Germany with a sense of security and the ability to allocate more resources to its planned invasion of Poland (September 1, 1939)

Soviet Union's Motivation for Territorial Expansion

• The Soviet Union aimed to gain time to strengthen its military and expand its territory in Eastern Europe, particularly in the Baltic states (Estonia, Latvia, Lithuania) and parts of Poland
• The pact's secret protocol divided Eastern Europe into German and Soviet spheres of influence, granting the Soviet Union control over significant territories
• The Soviet Union sought to create a buffer zone against potential future aggression from Germany by annexing neighboring countries
• The pact allowed the Soviet Union to pursue its expansionist goals without immediate interference from Germany or other European powers

Pact's Impact on European Power

Neutralization of Potential Alliances Against Germany

• The Nazi-Soviet Non-Aggression Pact significantly altered the balance of power in Europe by removing the threat of Soviet opposition to Germany's aggressive actions
• The pact effectively neutralized the possibility of a joint Anglo-French-Soviet alliance against Germany, which had been a potential deterrent to German expansion
• The removal of the Soviet Union as a potential ally against Germany weakened the position of other European powers, particularly France and the United Kingdom
• The pact's secret protocol, which was not initially known to other European powers, caught them off guard and made it difficult for them to respond effectively to the German and Soviet actions that followed

Vulnerability of Smaller Nations in Eastern Europe

• The division of Eastern Europe into German and Soviet spheres of influence left smaller nations, such as Poland, the Baltic states, and Finland, vulnerable to invasion and occupation
• Poland, which was partitioned between Germany and the Soviet Union, faced invasion from both sides (German invasion on September 1, 1939; Soviet invasion on September 17, 1939)
• The Baltic states of Estonia, Latvia, and Lithuania were annexed by the Soviet Union in June 1940, following the pact's provisions
• Finland was attacked by the Soviet Union in November 1939 (Winter War) and forced to make territorial concessions in March 1940

Soviet Union's Role in Early World War II

Invasion and Annexation of Neighboring Countries

• Following the signing of the Nazi-Soviet Non-Aggression Pact, the Soviet Union invaded and annexed the Baltic states of Estonia, Latvia, and Lithuania in June 1940
• The Soviet Union also invaded and occupied eastern Poland in September 1939, as per the secret protocol of the pact, while Germany invaded Poland from the west
• In November 1939, the Soviet Union launched an attack on Finland (Winter War), which lasted until March 1940 and resulted in territorial concessions from Finland to the Soviet Union
• The Soviet Union's actions were driven by its desire to expand its territory and create a buffer zone against potential future aggression from Germany

Collaboration with Germany and Escalation of Conflict

• The Soviet Union's role in the early stages of World War II was characterized by its collaboration with Germany, which allowed both countries to pursue their expansionist goals without immediate opposition from each other
• The Soviet Union's actions, particularly its invasion of Poland and the Baltic states, contributed to the escalation of the conflict and the suffering of the occupied populations
• The collaboration between Germany and the Soviet Union through the Nazi-Soviet Non-Aggression Pact played a significant role in the early stages of World War II
• The pact's impact on the balance of power and the subsequent actions taken by Germany and the Soviet Union set the stage for the global conflict that followed
