Episode notes
Army, Not Senate, Decides Power
- The auction shows the emperor's power rested on military support, not just senatorial approval.
- Control of the army defined real authority in Rome, exposing the imperial system's brittle reality.
Buying The Empire At The Gate
- Didius Julianus rushed to the Praetorian camp and shouted his bids from outside the gate when he couldn't enter.
- A soldier ran back and forth to relay his offers, and he ultimately showed boxes of money to win the auction.
Experienced Man, Tarnished Throne
- Didius Julianus had an extensive senatorial and military career, including legions and proconsulships.
- Yet his reputation was ruined by how he took power and by hostile sources written after his defeat.
