The German colonial empire is sometimes treated as a footnote — too short to matter. The historians who study its through-line to 1933–45 disagree[10].

Phase one
Land grab, 1884 – 1900
Otto von Bismarck, having previously dismissed colonies as luxury, joined the scramble at the Berlin Conference of 1884–85. Germany acquired South-West Africa, East Africa, Cameroon, and Togoland in quick succession, and the Pacific holdings shortly after. Administration was handed to chartered companies, then taken into the state after their financial failures.
Phase two
South-West Africa: the first 20th-century genocide
The Herero rising of January 1904 met the most explicit extermination order in the modern colonial record. General Lothar von Trotha's Vernichtungsbefehl of 2 October 1904 instructed German troops to shoot "every Herero, with or without a rifle, with or without cattle" inside the German borders. The Nama rising of 1905 was met with the same policy. Survivors were held in concentration camps; Shark Island had a mortality above 60%[10].
“The colonial experience in South-West Africa created an institutional and personal continuity with the Nazi system that historians can no longer ignore.”
Researchers at Shark Island — including Eugen Fischer, later a leading Nazi racial theorist and mentor to Josef Mengele — used Herero and Nama skulls and prisoners for racial-science experiments. See the dedicated page on the Herero & Nama Genocide.
Phase three
East Africa & Maji Maji, 1905 – 1907
The Maji Maji rebellion across southern German East Africa was triggered by forced cotton cultivation. German suppression — pioneered by Governor Gustav Adolf von Götzen — used scorched-earth tactics: burning villages, destroying granaries, starving regions into submission. The post-rebellion famine killed many more than the fighting; estimates run from 75,000 to 300,000.
The through-line
Why this matters disproportionately to its size
Hermann Göring's father, Heinrich Ernst Göring, was Imperial Commissioner of German South-West Africa. The personnel, the bureaucratic forms, the concentration-camp template, the racial-science legitimation — all crossed from the African colonies into the German metropole and re-emerged in the policies of the 1930s and 1940s. The argument from Zimmerer, Madley, Schaller and others is not that colonialism caused the Holocaust. It is that the Holocaust did not arrive without rehearsal.
