Caligula Assassinated
The Praetorian Guard murders its own emperor
In the underground corridors beneath Rome's Palatine Hill, members of the Praetorian Guard cornered Emperor Caligula and struck him down with their swords. The assassination, led by the officer Cassius Chaerea, ended a reign of terror marked by cruelty, excess, and madness. As Caligula's blood pooled on the palace floor, the guards proclaimed his uncle Claudius the new emperor, plucked from hiding behind a curtain to ascend the throne of the world.
