Biography
Publius Licinius Cornelius Saloninus Valerianus was a Roman emperor who ruled for a short time during the Crisis of the Third Century, a tumultuous period in the Roman Empire from 235 to 284 CE. Born around 242 CE in what is now Cologne, Saloninus was the grandson of Emperor Valerian I and the son of Emperor Gallienus. His brief time as emperor happened when the empire was dealing with threats from barbarian invasions, economic troubles, and political splits.
In 258 CE, at about sixteen, Saloninus was made Caesar by his grandfather Valerian I. This move was meant to ensure a clear line of succession during a time when imperial power was constantly under threat. Saloninus was given administrative duties over the German frontier, working from the key city of Cologne. This role placed him at the center of Rome's defense efforts against Germanic tribes along the Rhine.
Saloninus's situation worsened after a disagreement with Postumus, a powerful Roman general with a strong military following in Gaul. The conflict was over the division of war plunder, likely captured from barbarian raiders. Postumus had gained significant victories against Germanic tribes and wanted fair rewards. As the dispute grew, Saloninus found himself cut off from the empire's main support, as his father Gallienus was busy with threats elsewhere and his grandfather Valerian was fighting the Sassanid Empire.
In 260 CE, Saloninus's soldiers declared him Augustus, promoting him from Caesar to full emperor. This move was probably driven by the soldiers' loyalty and their resistance to Postumus's increasing power. Sadly, this decision was a grave mistake. Postumus reacted by besieging Cologne, where Saloninus had set up his headquarters. The siege was short but decisive, ending with the capture and execution of Saloninus and his praetorian prefect Silvanus. Postumus then proclaimed himself emperor, creating the breakaway Gallic Empire that would control Gaul, Britain, and parts of Spain for the next fourteen years. Saloninus’s death at eighteen marked the end of his brief but important part in the political struggles during the Crisis of the Third Century.
Before Fame
Saloninus was born into the top level of Roman society during a time of great crisis. As the son of Gallienus, who became emperor in 253 CE, and the grandson of Valerian I, his early life was shaped by the military and political duties of his imperial family. The Crisis of the Third Century meant that young members of the imperial family took on roles of authority much earlier than in past centuries.
His upbringing probably included the typical education for a Roman aristocrat, covering rhetoric, philosophy, military strategy, and the skills needed for governance. However, the chaotic political scene of the 250s meant his theoretical knowledge quickly had to be matched with practical experience on the frontier, where the empire's survival depended on effective military leadership and diplomatic skill in dealing with both Roman armies and barbarian threats.
