 The "Upper German" dialects of German are today found along the old Danubian frontier of the Roman empire, although eventually replaced by a Slavic language in Moravia and Slovakia, and probably descend from the languages of the southern Suebi such as the Quadi.The western area, inhabited by the Alemanni in late classical times, is home to Alemannic dialects.Dialects of Bavaria and Austria are in the related linguistically Bavarian group, which is geographically closer to the Quadi homeland.
