Publius Licinius Valerianus (c. 200 - after 260), known in English as Valerian, was Roman Emperor from 253 to 260.

Unlike the majority of the pretenders during the Crisis of the Third Century, Valerian was of a noble and traditional senatorial family. Details of his early life are elusive, but for his marriage to Egnatia Mariniana, who gave him two sons: later emperor Publius Licinius Egnatius Gallienus and Valerianus Minor.

In 238 he was princeps senatus, and Gordian I negotiated through him for Senatorial acknowledgement for his claim as emperor. In 251, when Decius revived the censorship with legislative and executive powers so extensive that it practically embraced the civil authority of the emperor, Valerian was chosen censor by the Senate. Under Decius he was nominated governor of the Rhine provinces of Noricum and Raetia and retained the confidence of his successor, Trebonianus Gallus, who asked him for reinforcements to quell the rebellion of Aemilianus in 253. Valerian headed south, but was too late: Gallus' own troops had killed him and joined Aemilianus before his arrival. The Raetian soldiers then proclaimed Valerian emperor and continued their march towards Rome. At the time of his arrival in September, Aemilianus' legions defected, killing him and proclaiming Valerian emperor. In Rome, the Senate quickly acknowledged him, not only for fear of reprisals, but also because he was one of their own.

Valerian's first act as emperor was to make his son Gallienus his colleague. In the beginning of his reign the affairs in Europe went from bad to worse and the whole West fell into disorder. In the East, Antioch had fallen into the hands of a Sassanid vassal, Armenia was occupied by Shapur I (Sapor). Valerian and Gallienus split the problems of the empire between the two, with the son taking the West and the father heading East to face the Persian threat.



By 257, Valerian had already recovered Antioch and returned the province of Syria to Roman control but in the following year, the Goths ravaged Asia Minor. Later in 259, he moved to Edessa, but an outbreak of plague killed a critical number of legionaries, weakening the Roman position. Valerian was then forced to seek terms with Shapur I. Sometime towards the end of 259, or at the beginning of 260, Valerian was defeated in the Battle of Edessa and taken prisoner by the Persians, making him the only Roman Emperor taken captive. According to the Augustan Histories, Valerian's capture was effected by treachery; the Persians agreed to meet with him, then seized him when they met.

According to the Catholic Encyclopedia article on Valerian: :"In 258, by a new and absolutely merciless edict, bishops, priests, and deacons were executed immediately, men of senatorial and equestrian rank were punished with degradation and confiscation of goods to be followed by death if they refused to offer heathen sacrifice, women were threatened with confiscation of their property and exile, and Christians in the imperial household were sent in chains to perform forced labour on the imperial domains. In this persecution Christian Rome and Carthage lost their leaders: Pope Sixtus was seized on 6 August, 258, in one of the Catacombs and was put to death; Cyprian of Carthage suffered martyrdom on 14 September. Another celebrated martyr was the Roman deacon St. Lawrence. In Spain Bishop Fructuosus of Tarragona and his two deacons were put to death on 21 January, 259. There were also executions in the eastern provinces (Eusebius, VII, xii). Taken altogether, however, the repressions were limited to scattered spots and had no great success."

An early Christian source, Lactantius, maintained that for some time prior to his death Valerian was subjected to the greatest insults by his captors, such as being used as a human footstool by Shapur when mounting his horse. According to this version of events, after a long period of such treatment Valerian offered Shapur a huge ransom for his release. In reply, according to one version, Shapur was said to have forced Valerian to swallow molten gold (the other version of his death is almost the same but it says that Valerian was killed by being flayed alive) and then had the unfortunate Valerian skinned and his skin stuffed with straw and preserved as a trophy in the main Persian temple. It was further alleged by Lactantius that it was only after a later Persian defeat against Rome that his skin was given a cremation and burial. The role of a Chinese prince held hostage by Shapur I, in the events following the death of Valerian has been frequently debated by historians, without reaching any definitive conclusion.



Some modern scholars believe that, contrary to Lactantius' account, Shapur I sent Valerian and some of his army to the city of Bishapur where they lived in relatively good condition. Shapur used the remaining soldiers in engineering and development plans. Band-e Kaisar (Caesar's dam) is one of the remnants of Roman engineering located near the ancient city of Susa. In all the stone carvings on Naghshe-Rostam, in Iran, Valerian is respected by holding hands with Shapur I, in sign of submission.

Other modern scholars tend to give at least some credence to Lactantius' account.

Valerian and Gallienus' joint rule was threatened several times by usurpers. Despite several usurpation attempts, Gallienus secured the throne until his own assassination in 268.

Owing to imperfect and often contradictory sources, the chronology and details of this reign are very uncertain.

* Gallienus * Valerianus Minor was the son of the Roman Emperor Valerian I. He was probably killed by usurpers, some time between the assassination of his father in 260 AD and that of his brother Gallienus in 268 AD.

*Gallienus usurpers for all the usurpers of Valerian and Gallienus reign.
