The Berlin Crises
How Berlin became the flashpoint of Cold War confrontation, from the 1948 blockade to the construction of the Wall in 1961.
A City Divided
After Germany's defeat in 1945, the Allied powers divided the country into four occupation zones: American, British, French, and Soviet. Berlin, located deep within the Soviet zone, was similarly split. This arrangement was meant to be temporary, but as the wartime alliance collapsed, the division hardened into a permanent standoff. West Berlin became a capitalist island surrounded by communist territory, a geographical anomaly that both sides saw as symbolically essential.
The Western powers introduced the Deutschmark in their zones in June 1948, a move Stalin interpreted as a step toward a permanently divided Germany aligned with the West. His response was dramatic: on June 24, 1948, Soviet forces blocked all road, rail, and canal access to West Berlin, cutting off 2.5 million people from food, fuel, and supplies. The Berlin Blockade was the first major crisis of the Cold War, and it forced the West into a stark choice: abandon Berlin, break through by force, or find another way.
