Reincke in Der alte Reichstag and der neue Bundesrat (Tubingen, 1906) points out a marked resemblance between the medieval archchancellor and the German imperial chancellor of the present day.
This threefold division of the office of imperial archchancellor was acknowledged in 1356 by the Golden Bull of the emperor Charles IV., but the duties of the office were performed by the elector of Mainz.
However this may be, during the 12th century the elector of Trier took the title of archchancellor for the kingdom of Arles, although it is doubtful if he ever performed any duties in connexion with this office.
He assumed the title of archchancellor of Gaul and Arles (or Burgundy), and in 1315 admitted the claim of the archbishop of Cologne to the highest place of ter the archbishop of Mainz among the spiritual princes of the empire.
However, the duties of archchancellor for Italy were generally discharged by deputy, and after the virtual separation of Italy and Germany, the title alone was retained by the elector.
