The Berlin Blockade of 1948 was a significant confrontation during the early Cold War, where the Soviet Union blocked all ground access to West Berlin in an attempt to force the Allies out of the city. This act was a response to the introduction of a new currency in West Germany and aimed to undermine Western influence in Berlin. The blockade lasted for nearly a year, leading to a major airlift operation by the Allies to supply the city and symbolizing the growing tensions between East and West.
