Who was the last emperor of the Julio-Claudian dynasty? (r. 54-68 AD)

The story behind the answer

Nero is correct: he ruled from AD 54 to 68 and was the fifth and final emperor of the Julio-Claudian line. The others reigned earlier—Augustus was the first, Caligula ruled 37–41, and Claudius 41–54—so none could be the last.

Nero’s death by suicide in 68 ended the dynasty and plunged Rome into the Year of the Four Emperors (69), a brief civil war. His reign is famous for artistic patronage and notorious for the Great Fire of Rome (AD 64), the lavish Domus Aurea, and persecution of Christians. To remember the dynasty’s order, try: “All Tigers Can Climb Nets” = Augustus, Tiberius, Caligula, Claudius, Nero.
