CARPI, a Dacian tribe established upon the lower Danube from the 1st century B.C. They rose to considerable power during the 3rd century A.D., and claiming to be superior to the Goths accordingly demanded that their incursions into Roman territory likewise should be bought off by tribute. When this was refused they invaded in force, but were beaten back by the emperor Philip. After this they joined with the Goths in their successful inroads until both nations were defeated by Claudius Gothicus. Later, after repeated defeats under Diocletian and Galerius, they were taken under Roman protection and the greater part established in the provinces of Pannonia and Moesia; some were left beyond the Danube, and they are last heard of as allies of the Huns and Sciri in the time of Theodosius I. Ptolemy speaks of Harpii and a town Harpis. This was no doubt the form the name assumed in the mouths of their Germanic neighbours, Bastarnae and Goths. (E. H. M.)
