Rome

Tiberius ruled from AD 14 to AD 37. He was a good general but a reluctant emperor. After the death of his son he exiled himself from Rome and left his prefects in charge. He died at age 77.
Caligula ruled from AD 37 to AD 41. He won a power struggle after Tiberiusdies. He was known for cruelty, extravagance, and perversity. He was an insane tyrant. He was assassinated by praetorian guards, Senators, and the imperial court trying to re-establish the republic.
Claudius ruled from AD41 to AD54. Many think he had cerebral palsy. He took over because he was the last male left in the family. He ruled well and ended up starting the conquest of Britian. He died by poisoning. This was his wife's plan so the son could rule.
Nero ruled from 54-68. He was big on arts. There was a huge fire in 64. He wanted Rome to be more majestic. He over spent, raided the temples for money. Historians don't look kindly on him.
