11. The Soviet Blockade of Berlin (1948-1949)
In 1948, the Soviet Union imposed a blockade on West Berlin, cutting off all land and water access to the city. This action aimed to force the Western Allies out of Berlin and was a significant early confrontation in the Cold War. In response, the Allies organized the Berlin Airlift, supplying the city by air for nearly a year. The blockade ended on May 12, 1949, but tensions between East and West continued to escalate (britannica.com).
