Aryan
Aryans, according to Nazi ideology, were the superior race to which Germans belonged. As such, they hoped to rid the world of non-Aryans. 

In an alternate timeline, extermination camps were a way of dealing with non-Aryans, though in 1944, Vosk suggested to a German general that they could create a deadly water-borne pathogen targeting non-Aryans. ()

In a World War II holoprogram in 2374, a German Kapitän told Karr that German blood was pure, and that "degenerate races" had brought corruption to their land, hence the need for Europe to be "purified". ()
