Since the reign of Charlemagne, this country is divided into High and Low Germany... the provinces of Lower Germany towards the north conſiſt of the Low Country of the Rhine, Triers, Cologn, Mentz, Weſtphalia, Heſſe, Brunſwic, Miſnia, Luſatia, High Saxony upon the Elbe, Low Saxony upon the Elbe, Mecklenburg, Lauenburg, Brandenburg, Magdeburg, and Pomerania.

Men like Fritz Reuter (employing the Mecklenburg dialect) and Klaus Groth (employing the Holstein dialect) have tried to raise it [= New-Low-German, or Plattdeutsch] to a written language.
