Cohors Primae Dacorum

The First Cohort of Daci

This unit was a one-thousand strong infantry unit levied from among the various iron-age tribes of the Roman province of Dacia, which lay in the region of modern eastern Romania, including parts of south-eastern Hungary and northern Yugoslavia. The unit is attested in numerous inscriptions from Birdoswald in Cumbria, all dating from the early third century, on an altarstone dedicated to Jupiter from Bewcastle, also from a single undated building inscription from the vallum to the rear of Hadrian's Wall, between Turret-7b and Milecastle-8. They are also possibly mentioned on a tombstone from High Rochester, north of the Wall, but the unit name may equally be Cohors I Dalmatarum.
