This document is a list of victory titles assumed by Roman Emperors, not including assumption of the title Imperator (is itself a victory title); note that the Roman Emperors were not the only persons to assume victory titles (Maximinus Thrax acquired his victory title during the reign of a previous Emperor). In many ways, the Imperial victory titles give an interesting summary of which wars and which peoples were considered significant by the senior leadership of the Roman Empire. For a more complete list of the Emperors themselves, see List of Roman Emperors.
Germanicus Maximus ("the Greatest German") and Sarmaticus Maximus ("the Greatest Sarmatian"), 285
Diocletian claimed the title Germanicus Maximus five more times (twice in 287, and in 288, 293, and 301) and the title Sarmaticus Maximus three more times (in 289, 294, and 300)
Maximian's victory titles are the same as those of Diocletian, except that he did not share Diocletian's first assumption of the titles Germanicus Maximus and Sarmaticus Maximus in 285
