Was Diocletian a good or bad emperor?

Answer 1

Vespasian was a good emperor. He is sometimes referred to as "the man who saved Rome". The treasury was depleted when he came into power due to Nero's extravagance and the previous civil war. Vespasian, consequently, was forced to tax just about everything--even urine. Fortunately for Rome, Titus was able to conquer Jerusalem and bring back the temple treasure to enrich the Roman state. After this Vespasian was able to embark on his building program of his temple and the Colosseum.

Answer 2

Diocletian did both good and bad things for Rome. But he is a good emperor because for one, he wasn't crazy for power. He also changed taxation and max prices to be fair for the people and changed the military. So yes, he was not a bad emperor, more of leaning towards good/decent.
