The notion of a distinct northern European race was also rejected by several anthropologists on scientific racist theories on the " Aryan race . " During the 1885 Anthropology Congress in Karlsruhe, Virchow denounced the " Nordic mysticism, " while Josef Kollmann, a collaborator of Virchow, stated that the people of Europe, be they German, Italian, English or French, belonged to a " mixture of various races, " furthermore declaring that the " results of craniology " led to " struggle against any theory concerning the superiority of this or that European race ".
