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
While the Roman
aristocracy thus took care of itself and got whatever occupied land
was still in its hands converted into its own property, it at the same
time pacified the Italian allies, not indeed by conferring on them the
property of the Latin domain-land which they and more especially their
municipal aristocracy enjoyed, but by preserving unimpaired the rights
in relation to it guaranteed to them by their charters.
The opposite
party was in the unfortunate position, that in the most important
material questions the interests of the Italians ran diametrically
counter to those of the opposition in the capital; in fact the
Italians entered into a species of league with the Roman government,
and sought and found protection from the senate against the
extravagant designs of various Roman demagogues.
