What is "leitkultur"

The German language term Leitkultur is a concept, first introduced in 1998 by the German-Arab sociologist Bassam Tibi. It can be translated as 'guiding culture' or 'leading culture', less literally as 'common culture', 'core culture' or 'basic culture'. Tibi himself saw it as a form of multiculturalism, but from 2000, the term figured prominently in the national political debate in Germany about national identity and immigration. The term then became associated with a monocultural vision of German society, with ideas of European cultural superiority, and with policies of compulsory cultural assimilation.
