Lucius Domitius Aurelianus, known in English as Aurelian, was the second of several highly successful "soldier-emperors" who helped the Roman Empire regain its power during the latter part of the third century and the beginning of the fourth. During his reign, the Empire was reunited in its entirety, following fifteen years of rebellion, the loss of two-thirds of its territory to break-away empires (the Palmyrene Empire in the east and the Gallic Empire in the west) and devastating barbarian invasions. His successes started the end of the empire's Crisis of the Third Century.
