Armenian Revolt
ArmeniaUnder Diocletian, Rome installed Tiridates III as ruler of Armenia, and in 287 he was in possession of the western parts of Armenian territory. The Sassanids stirred some nobles to revolt when Narseh left to take the Persian throne in 293. Rome nevertheless defeated Narseh in 298, and Khosrov II's son Tiridates III regained control over Armenia with the support of Roman soldiers.
