In this book, Jake Nabel analyzes Roman-Parthian interstate politics by focusing on a group of princes from the Arsacid family—the ruling dynasty of Parthia—who were sent to live at the Roman court. Although Roman authors called these figures “hostages” and scholars have studied them as such, Nabel draws on Iranian and Armenian sources to argue that the Parthians would have seen them as the emperor’s foster-children. These divergent perspectives allowed each empire to perceive itself as superior to the other, since the two sides interpreted the exchange of royal children through conflicting cultural frameworks. Moving beyond the paradigm of great powers in conflict, The Arsacids of Rome advances a new vision of interstate relations with misunderstanding at its center.
