In all Germanic languages, the variant of "folk" means "people" or something related to the people.
In German it is commonly used as prefix in words such as Volksentscheid (plebiscite) or Völkerbund (League of Nations), or the car manufacturer Volkswagen (literally, "people's car").
A number of völkisch movements were set up in Germany after World War I. Combining interest in folklore, ecology, occultism and romanticism with ethnic nationalism, their ideologies were a strong influence on the Nazi party, which itself was inspired by Adolf Hitler's membership of the Deutsche Arbeiterpartei (German Workers' Party).
During the years of the Third Reich, this term and its adjective völkisch became heavily politicised, particularly in slogans such as Volk ohne Raum — "(a) people without space" or Völkischer Beobachter ("popular observer"), an NSDAP party newspaper. Also the political slogan Ein Volk, ein Reich, ein Führer ("One people, one country/empire, one leader"). Today, the term völkisch is largely restricted to historical contexts describing that era.
The Nazi-era use of Volk could, depending on context, be interpreted as "race," "Germanic," or "European."
Because Volk is the generic German word for "people", its use does not necessarily denote any particular political views in post-1945 Germany.
