Macrinus is proclaimed emperor on eleventh of april, two and the birthday of septimius severus. He doesn't want to give the army the idea that there's been an upheaval. But he's completely a misleading them. Well, he even takes the name severus as well. Marcus r opelius ar severus macrinus am is his full titlature. We better know him as caracala but that he was named after the antonine dynasty.
