Play this story's trivia (3 questions)The phrase soviet union history often leads straight to World War II, and the story of the Eastern Front is one of the war’s defining chapters. It begins with a pact, turns into a massive German invasion, and ends with Soviet troops in Berlin.
Why did the Soviet Union sign a pact with Nazi Germany?
The Soviet Union signed a non-aggression pact with Nazi Germany in 1939 after failing to build an anti-Nazi coalition in Europe. That agreement bought time, but it did not stop the clash that came two years later.
Stalin refused to believe Hitler would invade and forbade defensive preparations. When Germany invaded the Soviet Union in 1941, the Soviet Union was caught completely unprepared for the attack.
What was Operation Barbarossa?
Operation Barbarossa was the Axis invasion of the Soviet Union. It opened the Eastern Front of World War II on 22 June 1941, and that front would run until 9 May 1945.
The invasion brought Germany and the Soviet Union into a struggle that stretched across cities, rivers, and vast stretches of territory. The Soviet Union became a crucial part of the Allies and played a decisive role in defeating the Axis powers.
The United States and the United Kingdom did not send ground troops to the Eastern Front, but they did provide substantial material aid to the Soviet Union through Lend-Lease.
How did the Eastern Front turn against Germany?
The Axis offensive on Moscow stalled and failed to capture the city. That was a major setback, but it was only the beginning of a longer collapse for German offensive power.
The Battle of Stalingrad was the bloodiest battle in the war and one of the key turning points of the front. Another major Axis defeat at Kursk crippled German offensive capabilities permanently.
Later, Operation Bagration destroyed Germany’s Army Group Center. By then, the balance on the Eastern Front had shifted so far that the endgame was closing in on Germany itself.
Why is the Eastern Front so central to World War II?
The Eastern Front accounted for enormous destruction and loss. The Soviet Union suffered around twenty-seven million casualties in World War II, the most deaths of any country in the war.
The final chapter came with the capture of Berlin and the German Instrument of Surrender on 8 May. The Eastern Front had begun with surprise and disaster for the Soviet Union, but it ended with Soviet forces in the heart of Germany.
For anyone tracing Soviet Union history in World War II, the arc is clear: a pact with Hitler, a devastating invasion, turning-point battles at Stalingrad and Kursk, and the drive that ended in Berlin.
