Final answer:
The rise of the Berlin Wall occurred in August 1961, when East German troops divided East and West Berlin with fences and cement walls to restrict free passage. The fall of the Berlin Wall happened in November 1989, when peaceful protestors tore down large portions of the wall, symbolizing the decline of Communism in Eastern Europe.
Step-by-step explanation:
The rise of the Berlin Wall occurred in August 1961 when East German troops erected a barbed wire fence to divide East and West Berlin. This was followed by the construction of cement walls to further restrict free passage between the two sides. The Berlin Wall was intended to prevent East Germans from fleeing to the West.
On the other hand, the fall of the Berlin Wall took place in November 1989. Peaceful protestors in East Germany, motivated by a larger movement for freedom sweeping across Eastern Europe, marched through checkpoints at the Berlin Wall. This led to a massive gathering of people from both East and West Berlin, who began tearing down chunks of the wall, symbolizing the decline of Communism in Eastern Europe.
