Südwest was a bit of a special issue since it was the only explicite settler colony. That played a role in the other colonies - especially East Afrika - as well, but a smaller one. Thus in the administration mainly two schools of thought dominated. A traditional one, which mainly saw them as resource provider and a reformist one, which hoped to gain a market by building the colonies up and also claimed (had?) some altruistic motives (the names for the schools are mine, but imo fitting). Now the difference is not always clear cut, many reformists saw swift actions against risings as necessary evil while a number of traditionalists did condemn unnecessary cruelity like that of Carl Peters.Interesting. I didn't know that. With this in mind, how do you think the rest of the colonies would be governed?
Helped by the handling of the Herero rising and some other colonial scandals the reformists temporarily managed to gain control of the colonial administration outside Südwest. That was already on the wane in 1914, but even a governor considered a traditionalist like Schnee in East Africa supported now some of the reformist politics especially the expansion of the public schools. Incidentially the British in East Africa did in 1924 estimate that they would still need some time to reach again the pre-war German education standards.
With the boost Lettow-Vorbeck´s actions will give the perception of the natives as noble subjects, the Germans probably will continue a more or less reformist policy. As I once heard in an interview with the grandson of a German-killed chief from East Africa "they were harsh, sometimes cruel, but they also gave us a lot." That being public education, beginnings of a health car system, a grammar following modern principles for the trade language Swahili and the beginnings of an infrastructure. How progressive they will govern will depend on the exact economic and political circumstances in the various colonies, internationally and in Germany itself.
