The Berlin Blockade was a significant event during the early stages of the Cold War that began in June 1948 and lasted until May 1949. It occurred when the Soviet Union blocked all ground routes to West Berlin, aiming to force the Allies to abandon the city. This action was a response to the introduction of a new currency in West Germany, which the Soviets opposed. In response to the blockade, the United States and its allies organized the Berlin Airlift, supplying West Berlin with food and fuel by air. Over the course of nearly a year, planes delivered essential goods, demonstrating the commitment of the Western powers to support the city and resist Soviet pressure. The blockade was lifted in May 1949, marking a pivotal moment in post-war Europe.
