In October 1938 Hlučín Area (Hlučínsko in Czech, Hultschiner Ländchen in German) of Moravian-Silesian Region which had been ceded to Czechoslovakia under the Treaty of Versailles was annexed by the Third Reich as a part of areas lost by Czechoslovakia in accordance with the Munich agreement. However, as distinct from other lost Czechoslovakian domains, it was not attached to Sudetengau (administrative region covering Sudetenland) but to Prussia (Upper Silesia).
