__NOTOC__
Year '''255 BC''' was a year of the [[Roman calendar|pre-Julian Roman calendar]]. At the time it was known as the '''Year of the Consulship of Nobilior and Paullus''' (or, less frequently, '''year 499 ''[[Ab urbe condita]]'''''). The denomination 255 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.

* The [[Battle of Adis]] (or Adys) is fought near the city of that name, {{convert|40|mi|km|abbr=off}} southeast of [[Carthage]], between Carthaginian forces and a [[Roman Republic|Roman]] army led by [[Marcus Atilius Regulus]]. The Romans inflict a crushing defeat upon the Carthaginians, and the latter then sue for peace. The ensuing negotiations between the parties lead to Regulus demanding Carthage agree to an unconditional surrender, cede [[Sicily]], [[Corsica]] and [[Sardinia]] to Rome, renounce the use of their navy, pay an [[indemnity]], and sign a [[vassal]]-like treaty. These terms are so harsh that the people of Carthage resolve to keep fighting.<ref>{{Cite web |last=LLC |first=Arcadian Venture |title=First Punic War {{!}} Battle of Adys |url=https://punicwars.org/first-punic-war/battle-of-adys |access-date=2022-12-01 |website=Arcadian Venture LLC |language=en}}</ref>
