Prussia after WWII

After World War I, West Prussia was lost to Poland, and East Prussia was separated from the rest of German Prussia in 1919, under the terms of the Treaty of Versailles. The other provinces of Prussia between the two World Wars were Rhine, Brandenburg, Pomerania, Berlin, Saxony, Schleswig-Holstein, Hannover, Westphalia, Grenzmark Posen-Westpreussen, Hessen-Nassau, and Hohenzollern, and Silesia. In 1947, after World War II, Prussia was abolished as a political unit and, with the exception of East Prussia, split into different parts of the four zones of occupation in Germany, which was controlled by France, Great Britain, the United States, and USSR. The northeastern part of East Prussia was annexed by the USSR, and the remainder was put under Polish control. Berlin was the capital of Prussia prior to World War II, and the principal cities included Frankfurt am Main, Cologne, Essen, Dortmund, Düsseldorf, Magdeburg, and Königsber. The state of Prussia was legally abolished in 1947 by the Allied Control Council, a group formed after World War II to resolve issues relating to Germany.
