Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
When the plebeians
were admitted into the curies, they were certainly also allowed to
constitute themselves -de jure- as--what in the earlier period they
could only have been -de facto-(10)--families and clans; but it is
distinctly recorded by tradition and in itself also very conceivable,
that only a portion of the plebeians proceeded so far as to constitute
-gentes-, and thus the new curiate assembly, in opposition to its original
character, included numerous members who belonged to no clan.
All the political prerogatives of the public assembly--as well the
decision on appeals in criminal causes, which indeed were essentially
political processes, as the nomination of magistrates and the adoption
or rejection of laws--were transferred to, or were now acquired by,
the assembled levy of those bound to military service; so that the
centuries now received the rights, as they had previously borne the
burdens, of citizens.
