In their attempt to scientifically prove the racial inferiority of Slavs, German (and Austrian) racial scientists were forced to gloss over their findings which consistently proved that Early Slavs were dolicocephalic and fair haired, i.e., "Nordic", while the South Slavic "Dinaric" sub-race was often viewed favourable. Nazis used the term "Slavic race", and considered Slavs to be non-Aryan The concept of a Slavic "Untermensch" accompanied their political goals, and it was particularly aimed at Poles and Russians. Germany's immediate goal was "Drang nach Osten" or expansion into the East, which was the first phase in its ultimate plan to conquer Europe, and Ukraine's "chernozem" (black earth) soil was regarded as a particularly desirable zone for colonization by the ""Herrenvolk"" (master race).
