After World War II, Germany was occupied by Britain, France, the United States and the Soviet Union. At the same time, because of the defeat of Nazi Germany, the Soviet Union and western countries began to have differences. And then gradually separated.
1June, 948, the United States, Britain and France merged the three divisions occupied by Germany. On May 23rd of the following year, the United States, Britain and France established the Federal Republic of Germany in this occupied area, namely "West Germany".
At the same time, in this year, the Soviet Union, the old rival of western countries, also introduced a means to establish the German Democratic Republic, that is, "East Germany", in the areas it occupied in the east. That is, from this day on, the former Germany became two different sovereign countries.
In this way, the two sides confronted 1990. At that time, German Chancellor Kohl seized the opportunity because the Soviet Union began to loosen its control over Eastern Europe. Then Cole successfully persuaded the United States, the Soviet Union, Britain, France and Poland, and then the five countries agreed to German reunification.
However, after the reunification of Germany, the long-term estrangement also caused some disharmony between the people of West Germany and East Germany. Although East Germany is a local tyrant in Eastern European countries, it is like a younger brother in front of West Germany. And there are cultural differences.
Generally speaking, the development of West Germany is much better than that of East Germany, so under such circumstances, it is inevitable that West Germany discriminates against East Germany.
