(1948–49) International crises that arose from an attempt by the Soviet Union to force the Allied powers (U.S., Britain, and France) to abandon their postwar jurisdictions in West Berlin.
The Soviets, regarding the economic consolidation of the three Allied occupation zones in Germany in 1948 as a threat to the East German economy, blockaded all transportation routes between Berlin and West Germany. The U.S. and Britain responded by supplying the city with food and other supplies by military air transport and airlifting out West Berlin exports. An Allied embargo on exports from the Eastern bloc forced the Soviets to lift the blockade after 11 months.
