Marcus Aurelius Probus (; 230–235 – September 282) was Roman emperor from 276 to 282. Probus was an active and successful general as well as a conscientious administrator, and in his reign of six years he secured prosperity for the inner provinces while withstanding repeated invasions of barbarian tribes on almost every sector of the frontier. After repelling the foreign enemies of the empire Probus was forced to handle several internal revolts, but demonstrated leniency and moderation to the vanquished wherever possible. In his reign the constitutional authority of the Roman Senate was fastidiously maintained, and the victorious Emperor, who had carried his army to victory over the Rhine, professed himself dependent on the sanction of the Senate. Upon defeating the Germans, Probus re-erected the ancient fortifications of emperor Hadrian between the Rhine and Danube rivers, protecting the Agri Decumates, and exacted from the vanquished a tribute of manpower to resettle depopulated provinces within the empire and provide for adequate defense of the frontiers. Despite his widespread popularity, Probus was killed in a mutiny of the soldiers while in the middle of preparations for the Persian war, which would be carried out under his successor Carus. Early life Probus was born between 230 and 235 (exact date of birth unknown) in Sirmium (modern day Sremska Mitrovica), Pannonia Inferior, the son of Dalmatius. According to the Alexandrian Chronicle, he was born sometime in the year 232. The unreliable Historia Augusta gives his father's name as Maximus and claims that his mother was of higher status than his father, that he had a sister named Claudia, that he was related to emperor Claudius Gothicus, his personal wealth was modest and his nearest kin unimportant. Besides his best known nomina Aurelius which can be found on most inscriptions, papyri and coinage, as well as Equitius attested on his coins from Ticinum and Pseudo-Aurelius Victor, the Historia Augusta gives him Valerius and Malalas Aelius. Military career Probus entered the army around 25 upon reaching adulthood. He rose rapidly through the ranks, repeatedly earning high military decorations. Appointed at a very young age as a military tribune by the emperor Valerian, in recognition of his latent ability, he justified the choice by a distinguished victory over the Sarmatians on the Illyrian frontier. During the chaotic years of the reign of Valerian, Illyria was the only province, generaled by such officers as Claudius, Aurelian and Probus,
