Trust is a fragile thing, and throughout history, betrayal has broken entire nations. Leaders tend to choose elite guards and brilliant generals to keep them safe from harm. Anyway, some stories demonstrate that the biggest threat is often from the person holding the shield. So here are some situations when the ones assigned with protection turned into villains.
#1: The Praetorian Guard & Emperor Pertinax (193 CE)
The Roman Emperor created the Praetorian Guard for personal security, but these soldiers preferred playing politics. In 193 CE, a strict reformer named Pertinax took the throne and tried to stop the Guard’s financial corruption. The angry protectors broke into the palace, murdered the emperor, and took his head through the streets.
