with Constantius' praetorian prefect, Asclepiodotus. Constantius himself had landed near Dubris (Dover) and marched on Londinium (London), whose citizens greeted him as a liberator. Campaigns in North Africa With Constantius' victorious return, Maximian was able to focus on the conflict in Mauretania (Northwest Africa). As Roman authority weakened during the third century, nomadic Berber tribes harassed settlements in the region with increasingly severe consequences. In 289, the governor of Mauretania Caesariensis (roughly modern Algeria) gained a temporary respite by pitting a small army against the Bavares and Quinquegentiani, but the raiders soon returned. In 296, Maximian raised an army, from Praetorian cohorts, Aquileian, Egyptian, and Danubian legionaries, Gallic and German auxiliaries, and Thracian recruits, advancing through Spain later that year. He may have defended the region against raiding Moors before crossing the Strait of Gibraltar into Mauretania Tingitana (roughly modern Morocco) to protect the area from Frankish pirates. By March 297, Maximian had begun a bloody offensive against the Berbers. The campaign was lengthy, and Maximian spent the winter of 297–298 resting in Carthage before returning to the field. Not content to drive them back into their homelands in the Atlas Mountains – from which they could continue to wage war – Maximian ventured deep into Berber territory. The terrain was unfavorable, and the Berbers were skilled at guerrilla warfare, but Maximian pressed on. Apparently wishing to inflict as much punishment as possible on the tribes, he devastated previously secure land, killed as many as he could, and drove the remainder back into the Sahara. His campaign was concluded by early 298 and, on 10 March, he made a triumphal entry into Carthage. Inscriptions there record the people's gratitude to Maximian, hailing him – as Constantius had been on his entry to London – as redditor lucis aeternae ("restorer of the eternal light"). Maximian returned to Italy in early 299 to celebrate another triumph in Rome. After his Mauretanian campaign in 299, Maximian returned to the north of Italy, living a life of leisure in palaces in Milan and Aquilea, and leaving warfare to his subordinate Constantius. Maximian was more aggressive in his relationship with the Senate than Constantius, and Lactantius contends that he terrorized senators, to the point of falsely charging and subsequently executing several, including the prefect of Rome in 301–2. In contrast, Constantius kept up good relations with the senatorial aristocracy and spent his time in active
