The Praetorian Guard and its origin:
Originally, a general in the Republic was protected by a guard called the 'Cohors Praetoria," named after the commander's headquarters (praetorium). The Praetorian Guard was named in imitation of the Cohors Praetoria, and when Augustus became the first ruler in 27 BC he decided such a formation was useful certainly not only in war, but also in politics.
