The Carpi or Carpiani were an ancient tribe (perhaps Dacian-speaking), that resided, between not later than ca. AD 100 and until at least ca. AD 300, in the eastern Carpathian Mountains, and in what became later the Principality of Moldavia (modern eastern Romania, Moldova, and small neighboring areas of Ukraine). The Carpi were one of the tribes of Dacia that apparently escaped subjugation by the Roman Empire when it annexed the central part of Dacia in AD 106. However, it is possible that the Carpi did not enter the Dacian region until (and maybe because of) the Dacian Wars (101-106), as they are not mentioned in the classical sources until the mid 2nd century. The group is first mentioned in the period following the Roman annexation of Dacia. After 150 years of obscurity, the Carpi emerged in ca. 240 as a major and persistent adversary of the Romans. In the period 240-70, the Carpi were an important component of a loose coalition of Transdanubian barbarian tribes that includedalso Germanic and Sarmatian elements.
