Do you guys know all the emperors, or do you get lost?
Some of my friends know the entire emperor list (including the years of their rule).
I know up to the 6 emperors of 235 AD, I think, though not the exact dates for most of them.
Augustus, Tiberius, Caligula, Claudius, Nero — Julio-Claudians
Galba, Otho, Vitellius, Vespasian, Titus, Domitian — 4 emperors of 69 AD, and then the Flavians
Nerva, Trajan, Hadrian, Antoninus Pius, Marcus Aurelius (with Lucius Verus) — 5 Good Emperors
Commodus — not really part of any grouping, but son of M. Aurelius
Pertinax, Didius Julianus, Septimius Severus, Pescennius Niger and Clodius Albinus (usurpers) — 5 emperors of 193 AD, and Sept. Sev. is the beginning of the Severan dynasty
Caracalla (with his brother Geta until he murdered him), Macrinus, Elagabalus, Severus Alexander* — Rest of the Severans
Maximinus Thrax, Gordian I and Gordian II, Balbinus and Pupienus**, Gordian III (6 emperors of 235 AD)
*this is an anagram of "Asexual Reverend", for those who are interested in such things
**this name sounds funny to an immature English speaker if pronounced out loud
OK, just checked, my list is correct except I forgot Macrinus' son Diadumenianus co-ruling with him.
