Berlin Blockade (1948-1949) was one of the first major international crises of the Cold War. During the multinational occupation of post–World War II Germany, the Soviet Union blocked the Western Allies' railway, road, and canal access to the sectors of Berlin under Western control. The Soviets offered to drop the blockade if the Western Allies withdrew the newly introduced Deutsche mark from West Berlin. In response, the Western Allies organized the Berlin airlift (26 June 1948 – 30 September 1949) to carry supplies to the people of West Berlin, a difficult feat given the size of the city's population.
