Olusoga and Erichsen's book is really in two parts. The first tells the story of German colonialism in South West Africa, showing how German policy towards the native Herero and Nama peoples developed into one of genocide. In chapters that are crucial reading to all who seek to understand the motives behind 19th century colonialism and imperialism the authors show how a philosophy of white racial supremacy emerged out of the ideas of Charles Darwin and was put into practice. Survival of the fittest becomes justification for white dominance over "inferior" indigenous peoples and genocide an acceptable option. This process is shown though as not just a German process and the German experience is placed in a global context: with British colonists in Tasmania, the US frontier wars, the Argentine wars of the desert all showing the same features.
In the German genocide against Herero and Nama we read of extermination orders, forced labour and concentration camps designed to kill off indigenous peoples who were articulate, politically able and well resourced, but ultimately doomed as the Kaiser's troops introduce a policy of "absolute terror and cruelty... by shedding rivers of blood and money" (General von Trotha) in which the missionary churches were actively complicit.
This alone is a story that needs telling widely, but the second part of the work shows the significance of this colonial experience for future nazism. The colonies first Governor was the father of Hermann Göring, the uniform of the SA was that of the Wilhelm II's brown shirted colonial army. More significantly, the colonial period saw the emergence of the pseudo science of eugenics and the legal framework to protect the purity of German settlers from racial contamination. Terms appear that are to be more infamously used later: Rassenschande (Racial shame), Rassenreinheit (Racial purity). Interracial marriage is made illegal. This was all to make the colony racially safe for emigration for a Volk that needed Lebensraum (living space) to expand into and escape population pressure at home. In the final chapters Olusoga and Erichsen skillfully show how these ideas survive the collapse of 1918 and become a core element of the politics of the right. Hitler uses his Landsberg imprisonment to read much of the work on race that emerged out of the Wilhelmine colonial experience. After 1933 races considered impure, German Jews and Gypsies, are subjected to the treatment first employed in South West Africa: Nuremberg Laws to end racial mixing; control and internment in concentration camps, forced labour, extermination. One chilling story is that of the 400 "Rhineland Bastards", children fathered by French colonial troops occupying the Rhineland after 1918. By 1937 all are sterilised.
There is a final twist in the argument. Hitler's war, it is argued, was ultimately one for colonial Lebensraum in the east. The German treatment of the eastern populations and Red Army was different to the western conflict as Hitler considered the eastern peoples to be similar to uncivilised indigenous colonial peoples. Fighting was more brutal, civilians were treated with even less regard. Necessary he believed to ensure Lebensaum and civilisation. The nazis compared this push East to how Wilhelm's troops had fought the Herero, or the British the Sudanese & Tasmanians, the US the Native Indians, or the Argentines with the tribes of the south.
Thought provoking, this is an important, thorough and well written work. It ranks with Hochschild's "King Leopold's Ghost" as an indictment of European colonialism but develops its arguments beyond normally considered confines to place the events of a short-lived German colony in a far wider context.
