Pupienus

Marcus Clodius Pupienus Maximus was born around 164 and ascended to the purple in 238, sharing power with Balbinus during one of the most chaotic stretches in imperial history. The sources that survive from the period are thin, leaving much of his reign in shadow. Contemporary writers called him "Maximus" rather than Pupienus, a detail preserved more reliably than the policies or battles that filled his three months. His co-rule ended the same year it began, in 238, when both emperors were killed.
