Jaron, your reading comprehension skills are somewhere between abysmal and nonexistant.
IF I DID think there WAS/IS a master race (which I noted that I -don't-), I'd pick the Germanic peoples. Not "German". "Germanic".
Who rose from an insignificant island to conquering a quarter of the globe?
Hint, it wasn't Japan.
I'm reasonably sure that sheer luck played a role. I'm also fairly sure that there's a reason why England conquered other than sheer luck.
I'm reasonably sure that Germany going from a group of princedoms to a power capable of threatening to take over the majority of Europe...twice...in the 1870s is a feat not to be taken lightly.
I'm reasonably sure that the kingdoms which rose as Rome fell were "Germanic".
You want to actually read the "if" instead of skimming over it? If I thought that the Germans (or simply Germanic barbarian descendants) were a Superior Race without question or doubt, I'd say so. I don't. I do think that they managed to do a great deal more than oh, the native tribes of the Americas and Africa.
Plenty of perfectly capable individuals of all races, but given that we all started at the same point, the fact that in 1850 Englishmen are using rifles and Zulus are using spears indicates that someone figured out how to advance technology and thusly power more effectively.
I despise the idea that there is an inherent superiority of any group over any other. I do think that some groups have managed to do better than others for reasons other than wild, unpredictable luck.
I'm positive that there are/were as many Africans who could be Nelsons as there are/were Englishmen. For some reason, they didn't appear.
In an alternate world, where Europe collapses into barbarism and stays there, and China doesn't stagnate, then I would be saying that Europe appears to be "cursed" (quotes intentional).
In -this- world, the descendants of the Franks, Goths, Lombards, Saxons, and so on who carved kingdoms out of the Roman Empire are the ones who dominated the planet.
In brief, for those who don't feel like reading a full explaination:
I'd put Shaka Zulu against Charlemagne with a pretty high level of confidence in Shaka, if it was a contest of tactics and strategy and so on.
I'm rather less than impressed that the Zulus are using spears in the era in which Europe is using repeating rifles and machine guns.
