The Berlin Airlift, which lasted from June 1948 to May 1949, was significant as it marked one of the first major crises of the Cold War. After World War II, Berlin was divided into East and West, with the Western Allies controlling West Berlin. In response to the Soviet blockade of all ground routes into West Berlin, the United States and its allies initiated an extensive airlift to supply the city. Over 200,000 flights delivered food, fuel, and essentials to the isolated population. The successful airlift not only showcased Western resolve against Soviet aggression but also solidified the division of Germany and Europe.
