During the second half of the 19th century Dutch was banned from all levels of education by both Prussia and France and lost most of its functions as a cultural language. In both Germany and France the Dutch standard language is largely absent and speakers of these Dutch dialects will use German or French in everyday speech. Dutch is not afforded legal status in France or Germany, either by the central or regional public authorities and knowledge of the language is declining among younger generations.
