"The Praetorian Guard (Latin: Praetoriani) was a force of bodyguards used by Roman Emperors. The title was already used during the Roman Republic for the guards of Roman generals, at least since the rise to prominence of the Scipio family around 275 BC. The Guard was dissolved by Emperor Constantine I in the 4th century. They were distinct from the Imperial Germanic bodyguard that provided close personal protection for the early Roman emperors."@en . . .
