Political map of Europe & the Mediterranean  summer 210 (Severus’ invasion of Caledonia): By 207 Septimius Severus felt the need to deal with the growing power of the Maeatae and Caledonians in northern Britain and traveled there with his son Caracalla. Marching beyond Hadrian’s Wall, Severus reestablished the Antonine Wall but was unable to pacify the region before his death in early 211 (Roman invasion of Caledonia 208–210). Now more concerned with the succession, Caracalla abandoned his father’s gains and returned to Rome.
