Agri Decumātes
“Tithe-lands.” The name given by the Romans to a part of Germany, east
of the Rhine and north of the Danube, which they took possession of when the Germans retired
eastward, and which they gave to the Gauls, and subsequently to their own veterans, on the
payment of a tenth of the produce (
decuma). Towards the beginning of the
second century A.D. these lands were incorporated in the Roman Empire.
