Carpians

The Carpi or Carpiani were an ancient people that resided in the eastern parts of modern Romania in the historical region of Moldavia from no later than c. AD 140 and until at least AD 318.

The ethnic affiliation of the Carpi remains disputed, as there is no direct evidence in the surviving ancient literary sources. A strong body of modern scholarly opinion considers that the Carpi were a tribe of the Dacian nation. Other scholars have linked the Carpi to a variety of ethnic groups, including Sarmatians, Thracians, Slavs, Germans, and Celts.

About a century after their earliest mention by Ptolemy, during which time their relations with Rome appear to have been peaceful, the Carpi emerged in c. 238 as among Rome's most persistent enemies. In the period AD 250-270, the Carpi were an important component of a loose coalition of transdanubian barbarian tribes that also included Germanic and Sarmatian elements. These were responsible for a series of large and devastating invasions of the Balkan regions of the empire which nearly caused its disintegration in the "Crisis of the Third Century".

In the period 270-318, the Roman "military emperors" acted to remove the Carpi threat to the empire's borders. Multiple crushing defeats were inflicted on the Carpi in 273, 297, 298-308 and in 317. After each, massive numbers of Carpi were forcibly transferred by the Roman military to the Roman province of Pannonia (modern western Hungary) as part of the emperors' policy of repopulating the devastated Danubian provinces with surrendered barbarian tribes. Since the Carpi are no longer mentioned in known documents after 318, it is possible that the Carpi were largely removed from the Carpathian region by c. 318 or, if any remained, it is possible that they mingled with other peoples resident or immigrating into Moldavia, such as the Sarmatians or Goths.

The Greco-Romans called this people the Carpi or Carpiani. Probably the earliest mention of them, under the name Καρπιανοί (Carpiani in Latin) is in the Geographia of the 2nd-century Greek geographer Ptolemy, composed c. AD 140.
