<em><u>At the end of the Second World War, Berlin was divided into four sectors of occupation</u></em>: <u>Soviet, French, English and American.
</u>
<u />
<u>Subsequently, in 1949 the eastern area that was held by the Soviets</u> <u><em>was under the jurisdiction of </em></u><u>the so-called German Democratic Republic (RDA)</u> <em><u>and the other three formed a single area governed by</u></em> <u>the Federal Republic of Germany (FRG).</u>
<em><u>In the following years, the western zone began to prosper while the Soviet side suffered economic problems</u></em>. <u>This, caused millions of Berliners who lived under the communist regime to migrate to West Berlin.
</u>
<u>It is for this reason that on the night of August 12, 1961 the authorities of the GDR decided to build a provisional wall that divided the city in two.
