Conquest strategy and political discourse: new evidence for the conquest of Dacia from LiDAR analysis at Sarmizegetusa Regia

Abstract

By the end of the 1st c. A.D., Dacia had been an intermittent thorn in Rome's side for almost two centuries. The ambitions of Burebista and the actions of his various successors continued to threaten Roman hegemony along the lower Danube, culminating in the rise of the powerful kingdom of Decebalus and a substantial Roman defeat in Moesia. Domitian sent troops against the Dacians to restore the dignity of Rome (85-86 and 88-88/89), but with mixed success, finally having to settle for buying peace at a substantial price in order to free himself to deal with threats to security in both Germany and Pannonia. No doubt both the costs involved and the perceived lack of success further contributed to the hostility of Roman authors towards Domitian and left unfinished business on the Danube frontier. It is no great surprise, therefore, that Dacia was the first area to which Trajan — to whom the attitude of contemporary sources (e.g., Pliny's Panegyricus) could not have been in greater contrast — turned his attention within three years of his accession.
