Upon Caligula's assassination in January, AD 41, Claudius was the sole surviving Julio-Claudian male. When members of the Praetorian Guard found him cowering behind a curtain in the palace, they immediately acclaimed him as Emperor and brought him to the Castra Praetoria, their fortified camp on the outskirts of Rome. Claudius astutely awarded the Praetorians a substantial bonus, and, with 10,000 heavily armed soldiers backing him, he easily forced the Senate to accept him as the next princeps. On this denarius, Claudius clearly acknowledges his debt to the Praetorians, depicting the walled Castra the legend IMPER RECEPT –- "The Emperor Received."
