Year 422 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Tribunate of Capitolinus, Mugillanus and Merenda (or, less frequently, year 332 Ab urbe condita). The denomination 422 BC 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.
