The euphrates as a boundary between rome and parthia in the late Republic and early empire

Abstract It is generally agreed that during the first century BC the Euphrates River came to represent a negotiated boundary of Roman and Parthian power in the Near East, and that this remained the case until the overthrow of the Parthians by the Sassanians in the third century AD. It was during the first century BC that the term imperium began to be used in the context of expressions of corporate Roman power; this eventually saw an additional important usage of the term evolve to that of an expression of physical territory, that is, empire, by the end of the reign of Augustus. This paper argues that it is possible to link the development of the Euphrates as a boundary of Roman and Parthian power in the first century BC with developments and changes in the usage of the term imperium. It traces the history of Roman and Parthian agreements and conflicts throughout the first century BC in the context of the development of the Euphrates as a boundary. The paper also argues that only the upper section of the Euphrates came to play this role and that previous analyses of the middle Euphrates have produced a misleading understanding of Roman and Parthian activity on this section of the river. The analysis of archaeological evidence from the first centuries BC and AD from the middle Euphrates site of Dura Europos is employed to illuminate the analysis of the Euphrates as a boundary. We arrive at a better understanding of Duras history during this period if we considert Dura in the broader context of the Euphrates’ role in dividing Roman and Parthian power.
