The Berlin Blockade (1948-1949) was a significant event during the Cold War, representing a high point of tension between the Western Allies and the Soviet Union. In response to the merging of the Western sectors of Germany and the introduction of the Deutschmark, the USSR blocked all ground access to West Berlin, hoping to force the Allies to withdraw. In retaliation, the Allies organized the Berlin Airlift, supplying West Berlin with essential goods through an extensive air operation. The successful airlift not only prevented the blockade's objective but also solidified the division of Germany into East and West, establishing a clear frontline in the Cold War.
