wrong the west made it
The soviets and east Germany
The Soviet Union didn't build the Berlin Wall. The Soviets merely told East German dictator Walter Ulbricht to stop the flow of defections from East to West or he would. East German Army engineer units built the Wall.
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.
East Berlin
The Berlin Wall was built, with the intentions of keeping East Berliners from escaping to free West Berlin.
It was build in East Berlin, by the East German government (presumably at the behest of the Soviet Union), on the East Geman side of the border between East and West Berlin. Its purpose was to prevent the escape of East German citizens to West Berlin.
east and west germany
To divide East and West Germany.
Western Allied troops were able to reach Berlin about the same time as the Soviets (Russians) did. Resulting in a future cold war of EAST and WEST Berlin. Had the allies NOT landed successfully, the Russians (Soviets) might have had Berlin all to themselves.
Berlin. It was divided into West Berlin (capitalist) and East Berlin (communist) by the Berlin Wall. The Berlin Wall was torn down in 1989, and East Berlin and West Berlin were formally reuinted in 1990.
East was communist and run by the Soviets. The West side was run by the Allies and remained free of Communism.
East Berlin and West Berlin are in Germany, not the Soviet Union. The city of Berlin was divided into four "sectors" after World War II. The Soviets got the eastern third of the city. The French got a small sector in the north of Berlin, the British got the middle part and the Americans the south.
