After the
World War I, most of
Austrian Silesia (including Opavian Silesia) became a part of the newly formed
Czechoslovakia.
Hlučín Region, a part of
Germany, became a part of Czechoslovakia on 4 February 1920 without a referendum. This was largely due to the fact that most of the regions inhabitants spoke
Czech.
Głubczyce (German:
Leobschütz, 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
World War II Głubczyce found itself within
Poland. From 1945 to 1946, the majority of the German population of Opavian Silesia was
expelled. ==See also==
