Maximian Herculeus

Marcus Aurelius Valerius Maximianus Herculius (c. 250 – c. July 310), commonly referred to as Maximian, was Caesar (junior Roman Emperor) from July 285 and Augustus (senior Roman Emperor) from April 1, 286 to May 1, 305. He shared the latter title with his co-emperor and superior, Diocletian, whose political brain complemented Maximian's military brawn. Maximian established his residence at Trier but spent most of his time on campaign. In the late summer of 285, he suppressed rebels in Gaul known as the Bagaudae. From 285 to 288, he fought against Germanic tribes along the Rhine frontier. Together with Diocletian, he ran a scorched earth campaign deep into the territory of the Alamanni tribes in 288, temporarily relieving the Rhenish provinces from the threat of Germanic invasion.
Maximian Hercules defeated the mauri, to exterminate the pirates (earning the nickname of Hercules) and returned to Rome in 303 for victory with Diocletian.
