The Year of the Four Emperors was a period of civil war in the Roman Empire between June 68 and December 69 when no less than four people became Roman Emperor and enjoyed the fruits of such power for a period of several weeks or even months if they were lucky. It ended with the last of these emperors, Vespasian, who managed to get everyone across the empire to "settle down" and "chill" and began a new imperial dynasty.
