Umvolkung (German: [ˈʔʊmˌfɔlkʊŋ]) is a term in Nazi ideology used to describe a process of assimilation of members of the German people (the Volk) as a way for them to forget about their language and their origin.
The term was invented by Albert Brackmann, a leader of the Ostforschung, a research organization that investigated the character and attitudes (Verhalten) of people living in areas east of the German Reich, such as Poland, Ukraine, Slovakia and Romania.
[citation needed] In contemporary politics, the term (or translations thereof, e.g. Dutch "omvolking"), is increasingly used by far-right groups and political parties to describe the process of replacement migration.
It suggested by left-wing groups and parties that this term concept denotes a nazi-conspiracy theory (or otherwise, a modern conspiracy known as the Great Replacement), suggesting that right-wing politicians spread the belief that "the elite" is intentionally replacing indigenous people by stimulating immigration and thus the growth of originally foreign populations, in order to ultimately exterminate European peoples, also known as the White genocide conspiracy theory.
[citation needed] Within nazism, the term was not used to suggest that, say, the Jews wanted to destroy the Germanic race through immigration.
