TheRoman theology of victory also referred to asJovian theology is a concept that considered victory as a legitimator of a political power or a claimant's divine right to rule.[1] It is invoked to support a political authority in the case of the failure or absence of traditional institutions.[2]

According toJ. Rufus Fears, the theology of victory originated in the ancientMediterranean world.[1][2] There are sources that specifically consider it ofGraeco-Roman origin.[3] It was fundamental, for instance, in establishing Hellenistic monarchs such asAlexander the Great.[2]
The concept was inherited during the third century by the Romans, who modified the concept their own way.[4] The theology of victory, thereafter, became associated with Rome with the way it was developed and embedded into the Roman imperial policy. Innovations were introduced beginning in Augustus' reign so that it was widely embraced by the time Commodus became the emperor.[5]
In Rome, the logic of the concept emphasized howfelicitas (good fortune or luck) is granted to the victor, who demonstratedvirtus or courage, manliness, and aggression.[1] During the republican period, this virtue was equivalent to human characteristics such as "bravery", "manliness", and "valor". When Rome eased into thePrincipate, however, thefelicitas connoted divine gift and formed part of the imperial theology of victory.[6] The idea is that earthly authority depended on heavenly accord. It was the basis of the view thatpax Romana (peace of Rome) mirroredpax deum (peace of the gods).[5]

The theology of victory was used to legitimize political power once the traditional ways of sanctioning political power failed.[1] Its efficacy drew from divine foundation since victory was considered an epiphany of the goddessVictoria. It held that successful conquest indicated a projection of supernatural gifts, legitimizing both sovereignty and divine status.[7]
The theology operates on the basis offelicitas. Gods granted this good fortune or luck to those who demonstratedvirtus (the masculine virtue for courage, manliness, and aggression) in battle so that those who won in the conflict were perceived to have been granted excessivevirtus. This meant that their victory manifested the god's choice of one potential ruling power or figure over another.[1]
Jupiter was a key figure to the Roman theology of victory. He was associated with the "religio-magical aspects of warfare, battle, and victory".[8] His authority was the basis of military prowess and articulated in the tradition that all victory stemmed from Jupiter's providence. Using this propaganda cemented that stature of new emperor's such asDiocletian, particularly, among a restive Roman military and in an empire fresh from a bruising civil conflict.[8] Coins commemoratingDomitian also represented him as Jupiter's vice-regent on earth.[9] He was depicted being crowned by Victoria while holding Jupiter's thunderbolt in his right hand.[9]
The Flavian dynasty's claim to power was linked to their victory inJudea.[10] It is said that its founderVespasian, who was from the plebeian class,[11] used the theology of victory to legitimize his ascension to the Principate. He applied the theology by promoting his victory over the Jews.[1] Aside from the records chronicling his campaign, his exploits were commemorated on victory arches as well as theFlavian Amphitheater.[10] The propaganda communicated that the Roman gods were superior to the gods of the Jews and that Vespasian and his son earned the approval of the gods having been granted good fortune.[1] This cemented that Flavian position due to the view that Rome ruled the world because god was on its side.[10] The Flavians would reinforce this through the adoption of Christianity and the imperial policy of peaceful co-existence in the drive to get the Roman empire to be viewed as a benefactor of the world.[5]
Some scholars cite the construction of Christian buildings and how subjects from the furthest reaches of the empire go to church as a testament and celebration of the triumph of the Roman empire.[12] This appropriation and reformulation of the Roman theology of victory replaced the imprint of the emperor's boot on a subdued people's back with the embrace of religion as the measure of subjection.[12] It is also referred to as the Byzantine theology of imperial victory.[6] The imperial rule and Christianity intersected and was successful due to the alignment of their respective goals: the subjugation of barbarian nations andJesus' command to evangelize nations.[12]
Some scholars challenged the tenets of the theology of victory. There were Roman authors who cited that the theology favors the warlords, citing that their victory was not only over their enemy but also over their own people. It is argued that the unequaledfelicitas is employed to legitimize the victors' infractions of the law and customs.[13]
