Imper(ium) recept(um): la qualificazione costituzionale dell'investitura di Claudio

The rise to power of emperor Claudius constituted a break with previous ways of imperial succession.
By examining the sources, the legal bibliography, not considered in the doctrina of the Roman Law, and the iconography coins with legendae IMPER RECEPT and PRAETOR RECEPT, this study tries to show that the imperial acclamation by Praetorian Guard should be viewed not as a simple political event but as a constitutional innovation in the practice of imperial succession, which will be followed by many emperors of the first century, especially by Vespasian.
