Abstract
"Völkisch" nationalism, whose origins date back to the 19th century, has expanded its influence since the time of the German Empire and survives to this day. The biographical article about Houston Stewart Chamberlain shows how the author of the famous book "Grundlagen des 19.
Jahrhunderts", who was also the son-in-law of the famous composer, Richard Wagner, influenced not only the conservative ideology of the 20. Century but also the national socialist ideology.
