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 neighbouring peoples had already attained a
high degree of culture, the Dalmatians were as yet unacquainted with
money, and divided their land, without recognizing any special right
of property in it, afresh every eight years among the members of

These tribes had in earlier times stood in a loose relation of
dependence on the rulers of Scodra, and had so far shared in the
chastisement inflicted by the Roman expeditions against queen
Teuta(6) and Demetrius of Pharos;(7) but on the accession of king
Genthius they had revolted and had thus escaped the fate which involved
southern Illyria in the fall of the Macedonian empire and rendered it
permanently dependent on Rome.(8)
