Aryan race
Chamberlain grouped all European peoples – not just Germans, but Celts, Slavs, Greeks, and Latins – into the "Aryan race", a race built on the ancient Proto-Indo-European culture. In fact, he even included the Berber people of North Africa in the Aryan race: "The noble Moor of Spain is anything but a pure Arab of the desert, he is half a Berber (from the Aryan family) and his veins are so full of Gothic blood that even at the present day noble inhabitants of Morocco can trace their descent back to Teutonic ancestors."
