Operation Barbarossa: Germany Invades the Soviet Union

On the timeline · around June 22, 1941 · Operation Barbarossa: Germany Invades the Soviet Union19411942

What happened

Germany launched Operation Barbarossa, invading the Soviet Union with roughly three million Axis troops along a vast front — the largest military operation in history. The attack broke the 1939 Nazi-Soviet Pact and opened the Eastern Front.

Why it matters

The Eastern Front became the deadliest theater of the war and the setting for much of the Holocaust; the invasion ultimately overextended and doomed Nazi Germany.
