Answer
Brief Explanations:
The fall of the Berlin Wall in 1989 was a significant event marking the end of the Cold - War division in Europe. After its fall, there was a trend towards greater European integration. The European Union continued to develop and expand, and efforts were made to create a single economic market. Europe was no longer as strictly divided along ideological lines as during the Cold War. Not all European nations joined NATO.
Answer:
