Himmler approved the idea of recruiting divisions of the Waffen-SS with volunteers from all nations under the banner of the struggle against Communist Russia and in defence of Europe and its civilisation. This was the restoration of the function that the Order of Teutonic Knights had in the beginning as guardian of the East and, at the same time, of the spirit that had animated the Freikorps, the voluntary groups that, on their own initiative, had fought against the Bolsheviks in the eastern regions and the Baltic countries after the end of the First World War. In the end, more than seventeen nations were represented in the Waffen-SS, often with their own complete divisions: French, Belgians, Dutch, Scandinavians, Ukrainians, Spaniards, even Swiss, with a total of about 800,000 men, of whom only a part came from the Germanic area.
