What was the Immediate Cause of the Second World War?

The Second World War was a complex and multifaceted conflict that can be attributed to a multitude of factors. However, the immediate cause of the war is widely agreed to be the invasion of Poland by Nazi Germany on September 1, 1939.

The Lead-Up to War

Before the invasion of Poland, Europe was already a highly volatile and unstable region. The Treaty of Versailles, which had ended World War I, had left deep-seated resentment among the German people and led to a surge in militarism and nationalism.

• The Rise of Hitler and the Nazi Party

  • In 1933, Adolf Hitler was appointed Chancellor of Germany by President Paul von Hindenburg.
  • Hitler capitalized on the economic and political crisis in Germany to consolidate his power and purge his enemies.
  • He transformed Germany into a totalitarian state, suppressing all opposition and dissent.

• Expansionist Policies

  • Hitler’s Nazi Party aggressively pursued an expansionist foreign policy, aiming to achieve "Lebensraum" (living space) for the German people.
  • Germany remilitarized the Rhineland, annexed Austria, and occupied Czechoslovakia.
  • Hitler’s ambitions were clearly stated in his book, "Mein Kampf," where he outlined his plans for German expansionism.

The Invasion of Poland

The invasion of Poland was the immediate catalyst for the Second World War. On September 1, 1939, German forces, led by General Heinz Guderian, crossed the border into Poland.

• The Polish Army’s Inadequate Preparedness

  • Poland had largely neglected its military modernization and was not prepared for a war against Germany and the Soviet Union.
  • The Polish Army consisted of outdated equipment and ill-trained troops.

• The Soviet Union’s Cooperation

  • On August 23, 1939, Germany and the Soviet Union signed the Molotov-Ribbentrop Pact, a non-aggression treaty that included a secret protocol dividing Eastern Europe into Soviet and German spheres of influence.
  • The Soviet Union invaded Poland on September 17, 1939, from the east.

The Outbreak of War

The invasion of Poland led to a prompt response from the United Kingdom and France, who had guaranteed Poland’s independence.

• Mobilization and Declarations of War

  • On September 3, 1939, the United Kingdom and France declared war on Germany.
  • The invasion of Poland and the resulting declarations of war marked the beginning of the Second World War.

The Bigger Picture

While the invasion of Poland was the immediate cause of the war, it was part of a larger pattern of aggressive expansionism and militarization in Europe.

• The Rise of Fascist and Nationalist Movements

  • Fascist and nationalist movements were rising to power in many parts of Europe, including Germany, Italy, and Austria.
  • These movements were characterized by a hatred of democracy, a veneration of authoritarianism, and a belief in the superiority of their respective nations.

• The Disarmament of the Western Powers

  • After World War I, many Western powers had disarmed and reduced their military forces, believing that the lessons of the war had established a lasting peace.
  • This left Germany with a significant military advantage over its neighbors.

Conclusion

The invasion of Poland was the immediate cause of the Second World War. The complex web of events and factors that led to this invasion included the rise of Hitler and the Nazi Party, Germany’s aggressive expansionism, and the Molotov-Ribbentrop Pact with the Soviet Union. The war had far-reaching consequences, affecting millions of people and resulting in unprecedented destruction and devastation.
