Trajan's final campaign against the Parthians was sparked by Parthia's replacement of the pro-Roman king of Armenia with one of their own in AD 114. Armenia had been a strategic and semi-independent kingdom which served as an important buffer between Parthia and Rome. The last conflict over this region, during Nero's reign, resulted in a delicate balance that stabilized the situation for over fifty years. The move by Parthia now upset the balance and posed a threat to Rome's wealthy Syrian cities. Trajan’s campaign was swift and decisive; by 115, Armenia was restored as a Roman client state. To secure the eastern frontier, he then moved southward through Mesopotamia, and captured the Parthian capital, Ctesiphon, in 116. Although short-lived, these victories were celebrated on much of Trajan's later coinage.
