What was an effect of the division of Berlin?
Also, how did the division of Germany affect the Cold War?
The division of Germany into occupation zones at the end of World War II was actually agreed upon before the end of the war. Berlin, divided but within East Germany itself, was especially problematic, and the Soviets in an attempt to unify the city under communist control sealed off the city from West Germany.
Just so, what did the Berlin Wall cause?
The wall was built to keep the country's people in. But the Soviets and East German government said it was to keep capitalism out. They said that West Germany refused to recognize East Germany as an independent country because they wanted to take over North-East Germany just like Hitler took over Poland.
The Berlin Wall was more than just a barrier, and a physical division of East and West Berlin. It was a symbolic boundary between communism and capitalism. West Germany would become a thriving capitalist and democratic state whilst East Germany communist.
