The Year of the Six Emperors refers to the year 238, during which six people were recognised as emperors of Rome.
The emperor at the beginning of the year was Maximinus Thrax, who had ruled since 235. Later sources claim he was a cruel tyrant, and in January 238 a revolt erupted in North Africa. The Historia Augusta states:
"The Romans could bear his barbarities no longer — the way in which he called up informers and incited accusers, invented false offences, killed innocent men, condemned all whoever came to trial, reduced the richest men to utter poverty and never sought money anywhere save in some other's ruin, put many generals and many men of consular rank to death for no offence, carried others about in waggons without food and drink, and kept others in confinement, in short neglected nothing which he thought might prove effectual for cruelty — and, unable to suffer these things longer, they rose against him in revolt."
