List of Thirty Tyrants (Roman)

The Thirty Tyrants (Latin: "Tyranni Triginta") were a series of thirty rulers who appear in the "Historia Augusta" as having ostensibly been pretenders to the throne of the Roman Empire during the reign of the emperor Gallienus.
Given the notorious unreliability of the "Historia Augusta", the veracity of this list is debatable; there is a scholarly consensus that the author deliberately inflated the number of pretenders in order to parallel the Thirty Tyrants of Athens.
The "Historia" actually gives 32 names; however, because the author (who wrote under the name of Trebellius Pollio) places the last two during the reigns of Maximinus Thrax and Claudius II respectively, this leaves thirty alleged pretenders during the reign of Gallienus.
