Year '''321''' ('''[[Roman numerals|CCCXXI]]''') was a [[common year starting on Sunday]] of the [[Julian calendar]]. In the [[Roman Empire]], it was known as the '''Year of the Consulship of Crispus and Constantinus''' (or, less frequently, '''year 1074 ''[[Ab urbe condita]]'''''). The denomination 321 for this year has been used since the early medieval period, when the [[Anno Domini]] [[calendar era]] became the prevalent method in Europe for naming years.
