Episode notes
Rapid Rise To Power
- Tiberius named Caligula joint heir, and when Tiberius died in 37 the Praetorian Guard quickly declared Caligula emperor.
- The Senate confirmed him and his rival Gemellus was soon dead, leaving Caligula sole ruler.
Honeymoon Then Rapid Decline
- Caligula's early months were popular because he reversed Tiberius' repressive policies and sponsored games and public generosity.
- This initial goodwill faded as his behavior and fiscal demands escalated after a severe illness.
Illness As Turning Point
- A near-fatal illness in late 37 coincided with a sharp change in Caligula's behavior and governing style.
- Gary Arndt notes historians link the illness to encephalitis or poisoning but its role remains central to narratives of his madness.
