Nymphidius Sabinus was born as the son of a Roman freedwoman. After Nero died, he supported first Galba, and then offered himself for the purple by claiming to be the bastard son of the late Emperor Caligula. Nobody seems to have taken his claim seriously, and he was murdered before Galba arrived at Rome.
Say Sabinus had survived (and was the son of Caligula as he claimed). What effects might this have had on Rome's history? Could he have found significant support to go against Galba etc? Or would he just be jotted down as a forgotten footnote of the Year of the Four Emperors as he usually is?
Thoughts?
