In 85 AD the Dacian army began minor raids upon the heavily fortified Roman province of Moesia, located south of the Danube. In 86 King Duras ordered a more vigorous attack south into Moesia. Roman sources refer to the attack being led by "Diurpaneus" (or "Dorpaneus"). Many authors have taken this person to be Duras himself, and refer to him as "Duras-Diurpaneus". Other scholars argue that Duras and Diurpaneus are different individuals, or that Diurpaneus is identical to Decebalus. Recent sources take the view that "Diurpaneus" is most likely Decebalus.
