326

At the time, it was known as the Year of the Consulship of Constantinus and Constantinus (or, less frequently, year 1079 Ab urbe condita). The denomination 326 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.
