After the Second World War German (and Austrian) law doctrine has kept on producing syntheses which thirsted for the honoured academic name of Staatslehre. But the last classic season is the one which begins with the Allgemeine Staatslehre by Georg Jellinek in 1900 and ends up with the Staatslehre by Hermann Heller (1934). During these three decades we have the impotant syntheses by Max Weber, Hans Kelsen, Carl Schmitt, Rudolf Smend, which try to give a unitary answer to the separation between social doctrine and law doctrine of the State put forward by Jellinek. Recently Jellinek’s theory has been taken up again, also in order to redefine the nature of the cathegories of public law.
