Areas along the northern, southern, and western borders of Bohemia, Moravia and Silesia inhabited by German speakers known as “Sudeten Germans.” The Sudetenland belonged to Austria-Hungary until 1918 when, following the First World War, the Austro-Hungarian state was dissolved and these territories were ceded to the new Czechoslovakian state. Hitler demanded the return of the Sudetenland to the German Reich under threats of war. Following negotiations with Great Britain, France and Italy in September 1938 (Munich Agreement), Germany annexed the Sudetenland in exchange for a pledge to keep the peace.
