Because it was a divided city with various sectors under the control of different countries and located in an area controlled only by the Soviet Union.
The German city of Berlin was known as the divided city. After World War II, Berlin was split into East Berlin and West Berlin.
East Berlin was the capital of what was commonly referred to as East Germany. The three main Western allies in World War Two, the British, French and US forces held one half of Berlin and the East German government held the other half. As an aside, East Germany was a proxy state of the Soviet Union.
The Berlin Wall was built by the German Democratic Republic during the Cold War to prevent its population from escaping Soviet-controlled East Berlin to West Berlin, which was controlled by the major Western Allies. It divided the city of Berlin into two physically and ideologically contrasting zones.
The Soviet Union.
The western half of Germany was controlled by the French, Americans and Brits after World War 2 concluded. The French controlled the section near the border of France and Germany. The US controlled a "middle section" and the Brits controlled the northern area. The allies also controlled different sections of the capitol city of Berlin. The Soviets controlled East Berlin and East Germany and Eastern Europe after the war.
BERLIN
West Berlin was isolated within soviet controlled germany. the berlin airlift stopped the city from staving to death when the soviets cut off the only road from west germany to west berlin.
The Berlin Airlift was a military operation designed to provide food and supplies to the city of Berlin from 1948-1949. After World War II, German and the city of Berlin were divided into four sections, each controlled by a separate power: the United States, Great Britain, France, and the Soviet Union. Berlin was in the Soviet section of German and the Soviet Union wanted to take complete control of Berlin, so they blocked all of the roads and railways into Western Berlin in order to force the other nations to abandon the city. In response, the Western governments began flying supplies into the city in order to circumvent the Soviet blockade.
Berlin was part of the axis powers as it was a German city.
Berlin was the city in Europe that was divided into four sectors following World War II. The sectors were controlled by the United States, the United Kingdom, France, and the Soviet Union. This division symbolized the broader geopolitical tensions of the Cold War and ultimately led to the construction of the Berlin Wall in 1961, separating East and West Berlin.
Berlin was divided into East Berlin and West Berlin because the Soviets refused to let East Berlin and East Germany be a free, democratic nation and city.
