5.2 The Berlin Blockade: causes and consequences

The Berlin Blockade was a pivotal moment in post-war Europe. As tensions rose between the Allies and Soviets, Germany became ground zero for the emerging Cold War. The blockade of West Berlin in 1948 marked a dramatic escalation, pushing the world to the brink of conflict.

The Western Allies responded with a massive airlift, flying in supplies to sustain West Berlin. This show of resolve not only thwarted Soviet aims but also solidified Western commitment to a free Berlin. The blockade's failure set the stage for the formal division of Germany and the hardening of Cold War battle lines.
