East Central German

East Central German or East Middle German (Ostmitteldeutsch) is the eastern Central German language and is part of High German. Present-day Standard German as a High German variant, has actually developed from a compromise of East Central (especially Upper Saxon that was promoted by Johann Christoph Gottsched) and East Franconian German. East Central German dialects are mainly spoken in Central Germany and parts of Brandenburg, and were formerly also spoken in Silesia and Bohemia.
