While the Roman emperor Trajan's two campaigns against the Dacian people (AD 101���02 and 105���06) are widely known, the earlier conflicts between the Dacians and their Roman neighbours are also important. Drawing upon the latest research and findings, this fully illustrated study investigates the emperor Domitian's Dacian war (AD 86���88) as well as Trajan's campaigns. Inhabiting an area of Europe from the Tisza River to the Black Sea, the Dacians mounted raids into Roman territory throughout the 1st century AD. In 85 Dacian forces invaded Roman territory; after defeating the invaders, the Roman Army moved into Dacia. Distracted by other crises, Domitian made peace and Dacia became a client kingdom of Rome. In AD 101, the emperor Trajan launched a pre-emptive strike on Dacia, prompting the Dacians to sue for peace in 102. In 105, Trajan's troops commenced a new campaign; the Romans besieged the Dacian capital, Sarmizegetusa. After the Dacian king committed suicide, a new Roman province of Dacia was established. Featuring specially commissioned full-colour artwork and mapping, this study pits the might of the Roman Army against the formidable Dacians, showing how the fighting men of both sides adapted their tactics and technologies as the fighting progressed.
