After the First World War, most of Austrian Silesia (including Opavian Silesia) became a part of the newly formed Czechoslovakia. Hlučínsko, a part of Germany, became a part of Czechoslovakia on On February 4, 1920 without a referendum. This was largely due to the fact that most of the regions inhabitants spoke Czech. Leobschütz (Polish: "Głubczyce", Czech: "Hlubčice" or "Glubčice"), a town in northern Opavian Silesia, was supposed to come under the administration of Czechoslovakia if the rest of the Upper Silesian Plebiscite area fell to Poland. That however never happened, and after the Second World War Leobschütz/Głubczyce found itself within Poland.
