In the Balkan Peninsula there is little to show for the floods of Nordic blood that have poured in for the last 3,500 years, beginning with the Achæans of Homer, who first appeared _en masse_ about 1400 B. C. and were followed successively by the Dorians, Cimmerians and Gauls, down to the Goths and the Varangians of Byzantine times. The tall stature of the population along the Illyrian Alps from the Tyrol to Albania on the south is undoubtedly of Nordic origin and dates from some of these early invasions, but these Illyrians have been so crossed with Slavs that all other blond elements have been lost and the existing population is essentially of brachycephalic Alpine type. They are known as the Dinaric race. What few remnants of blondness occur in this district, more particularly in Albania, as well as the so-called Frankish elements in Bosnia, may probably be attributed to later infiltrations. The Tyrolese seem to be largely Nordic except in respect to their round skull. In Russia and in Poland the Nordic stature, blondness and long skull grow less and less pronounced as one proceeds south and east from the Gulf of Finland. It would appear that in all those parts of Europe outside of its natural habitat, the Nordic blood is on the wane from England to Italy and that the ancient, acclimated and primitive populations of Alpine and Mediterranean race are subtly reasserting their long lost political power through a high breeding rate and democratic institutions. In western Europe the first wave of the Nordic tribes appeared about three thousand years ago and was followed by other invasions with the Nordic element becoming stronger until after the fall of Rome whole tribes moved into its provinces, Teutonizing them more or less for varying lengths of time.
