Berlin History

Berlin History

In 1945, after the end of World War II, Germany was divided in sections which were being controlled by different foreign governments. There were 4 sections: British, American, French in the West and Soviet in the East. They started to put restrictions on passing through the sections like the Interzonenpass which people had to carry and show to travel between sections.
Then, many other limitations happened like the Berlin blockade which only lasted a year and then on 1949, the Federal Republic of Germany (West Germany) was founded. Months later, the German Democratic Republic (East Germany) was founded; this brought the two sections even farther apart and was one of the many causes to the Berlin Wall.
On 1952, the border between East and West Germany was closes, only the borders between East and West Berlin were still open. By 1957, things were very controlled and leaving one part without permission could even lead up to prison. In 1961, the Brandenburg Gate and the sectorial border between East and West Berlin were closed; barriers were built between East and West.
Ten years later on 1971 due to the Four Power’s Agreement over Berlin became visiting easier for West Berlin. In 2 different years, two U.S. presidents tried to end this situation but they were unsuccessful.
Finally on 1989 the Berlin Wall was opened and later in the same year, the Brandenburg Gate was also opened. By 1990, Germany was reunited.
