__NOTOC__
Year '''432 BC''' was a year of the [[Roman calendar|pre-Julian Roman calendar]]. At the time, it was known as the '''Year of the Tribunate of Mamercus, Albinus and Medullinus''' (or, less frequently, '''year 322 ''[[Ab urbe condita]]'''''). The denomination 432 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.
