Roman Emperor (Crisis of The Third Century) - History

History

The situation of the Roman Empire became dire in A.D. 235, when the emperor Alexander Severus was murdered by his own troops. Many Roman legions had been defeated during a campaign against Germanic peoples raiding across the borders, while the emperor was focused primarily on the dangers from the Sassanid Persian Empire. Leading his troops personally, Alexander Severus resorted to diplomacy and paying tribute in an attempt to pacify the Germanic chieftains quickly. This may have cost him the respect of his troops, who may have felt they should be punishing the tribes who were intruding on Rome's territory.

In the years following the emperor's death, generals of the Roman army fought each other for control of the Empire and neglected their duties in preventing invasions from foreigners. Provincials became victims of frequent raids by foreign tribes, such as the Carpians, Goths, Vandals, and Alamanni, along the Rhine and Danube Rivers in the western part of the Empire, as well as attacks from Sassanids in the eastern part of the Empire. Additionally, in 251, the Plague of Cyprian (possibly smallpox), broke out, causing large-scale mortality which may have seriously affected the ability of the Empire to defend itself.

By 258, the Roman Empire broke up into three competing states. The Roman provinces of Gaul, Britain and Hispania broke off to form the Gallic Empire and, two years later in 260, the eastern provinces of Syria, Palestine and Aegyptus became independent as the Palmyrene Empire, leaving the remaining Italian-centered Roman Empire-proper in the middle.

An invasion by a vast host of Goths was beaten back at the Battle of Naissus in 269. This victory was significant as the turning point of the crisis, when a series of tough, energetic soldier-emperors took power. Victories by the emperor Claudius II Gothicus over the next two years drove back the Alamanni and recovered Hispania from the Gallic Empire. When Claudius died in 270 of the plague, Aurelian, who had commanded the cavalry at Naissus, succeeded him as the emperor and continued the restoration of the Empire.

Aurelian reigned (270–275) through the worst of the crisis, defeating the Vandals, the Visigoths, the Palmyrenes, the Persians, and then the remainder of the Gallic Empire. By late 274, the Roman Empire was reunited into a single entity, and the frontier troops were back in place. More than a century passed before Rome again lost military ascendancy over its external enemies. However, dozens of formerly thriving cities, especially in the Western Empire, had been ruined, their populations dispersed and, with the breakdown of the economic system, could not be rebuilt. Major cities and towns, even Rome itself, had not needed fortifications for many centuries; many now surrounded themselves with thick walls.

Finally, although Aurelian had played a significant role in restoring the Empire's borders from external threat, more fundamental problems remained. In particular, the right of succession had never been clearly defined in the Roman Empire, leading to continuous civil wars as competing factions in the military, Senate and other parties put forward their favoured candidate for emperor. Another issue was the sheer size of the Empire, which made it difficult for a single autocratic ruler to effectively manage multiple threats at the same time. These continuing problems would be radically addressed by Diocletian, allowing the Empire to survive in the West for over a century, and in the East for over a millennium.
