The Greater Germanic Reich (German: Großgermanisches Reich), fully styled the Greater Germanic Reich of the German Nation (German: Großgermanisches Reich der Deutschen Nation), was the official state name of the political entity that Nazi Germany tried to establish in Europe during World War II. The territorial claims for the Greater Germanic Reich fluctuated over time. As early as the autumn of 1933, Adolf Hitler envisioned annexing such territories as Bohemia, western Poland, and Austria to Germany and the formation of satellite or puppet states without independent economies or policies of their own.
This pan-Germanic Empire was expected to assimilate practically all of Germanic Europe into an enormously expanded Reich. Territorially speaking, this encompassed the already-enlarged German Reich itself (consisting of pre-1938 Germany proper, Austria, Bohemia, Moravia, Czech Silesia, Alsace-Lorraine, Eupen-Malmedy, Memel, Lower Styria, Upper Carniola, Southern Carinthia, Danzig, and Poland), the Netherlands, Belgium, Luxembourg, Denmark, Norway, Sweden, Iceland, Liechtenstein, parts of northern and northeastern France, and the German-speaking and French-speaking parts of Switzerland.
