TETRICUS II (273-274)

"The Last Gallic Usurper" He was the final self-proclaimed ruler of the so-called Imperium Galliarum, with its capital in Trier, and one of the successors of Marcus Cassianus Postumus, who declared himself emperor in 260 CE. He ruled alongside his father, Tetricus I, as Caesar and held the title princeps iuventutis.

Numismatic evidence, such as coins bearing the inscription IMPP AVGG (Imperatores Augustorum), suggests he was later elevated to the rank of Augustus as a co-ruler. He voluntarily surrendered to the legitimate Roman Emperor, Aurelian, in 274 CE. A year later, he, along with the defeated Queen Zenobia of Palmyra, was paraded in Emperor Aurelian’s grand triumphal procession.
