Numerian

Numerian was the younger son of Carus. In 282, the legions of the upper Danube in Raetia and Noricum proclaimed as emperor Numerian's father, the praetorian prefect Marcus Aurelius Carus, after a mutiny against the emperor Probus, in which the latter was killed. By one account, Carus had himself rebelled against the emperor, and Probus' army, stationed in Sirmium (Sremska Mitrovica, Serbia), decided they did not wish to fight Carus and assassinated their emperor instead. According to the Historia Augusta, Carus was not responsible for Probus's death, and inflicted severe punishment upon the murderers. Carus, already sixty, wished to establish a dynasty and immediately elevated Carinus and Numerian to the rank of Caesar. In 283, Carus left Carinus in charge of the West and moved with Numerian and his praetorian prefect Arrius Aper to the East to wage war against the Sassanid Empire. The Sassanids had been embroiled in a succession dispute since the death of Shapur and were in no position to oppose Carus' advance. According to Zonaras, Eutropius, and Festus, Carus won a major victory against the Persians, taking Seleucia and the Sassanid capital of Ctesiphon (near modern Al-Mada'in, Iraq), cities on opposite banks of the Tigris.
