Political map of Europe & the Mediterranean 31 July 59 AD (War of the Armenian Succession): In 54 AD the Armenians rose up against Rhadamistus’ rule, restoring the Parthian prince Tiridates (Tiridates I of Armenia) to power. The Roman emperor Nero—who had succeeded Claudius that year—asked Tiridates to Rome to receive his crown as a client king, but was rebuffed. In response, the Romans invaded Armenia (Roman–Parthian War of 58–63), deposing Tiridates and placing their own candidate (Tigranes VI of Armenia) on the throne.
