Year **255 BC** was a year of the [pre-Julian Roman calendar](/source/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](/source/Ab_urbe_condita)***). The denomination 255 BC for this year has been used since the early medieval period, when the [Anno Domini](/source/Anno_Domini) [calendar era](/source/Calendar_era) became the prevalent method in Europe for naming years.

## Events

### By place

#### Roman Republic

- The [Battle of Adis](/source/Battle_of_Adis) (or Adys) is fought near the city of that name, 40 miles (64 kilometres) southeast of [Carthage](/source/Carthage), between Carthaginian forces and a [Roman](/source/Roman_Republic) army led by [Marcus Atilius Regulus](/source/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](/source/Sicily), [Corsica](/source/Corsica) and [Sardinia](/source/Sardinia) to Rome, renounce the use of their navy, pay an [indemnity](/source/Indemnity), and sign a [vassal](/source/Vassal)-like treaty. These terms are so harsh that the people of Carthage resolve to keep fighting.[1]

- The Carthaginians, angered by Regulus' demands, hire [Xanthippus](/source/Xanthippus_of_Carthage), a [Spartan](/source/Sparta) mercenary, to reorganize the army. The revitalised Carthaginian army, led by Xanthippus, decisively defeat the Romans in the [Battle of Tunis](/source/Battle_of_Tunis) and capture their commander Marcus Atilius Regulus. A Roman fleet, sent to rescue Regulus and his troops, is [wrecked in a storm](/source/Sinking_of_the_Roman_fleet_(255_BC)) off Sicily.[2]

#### Egypt

- In the [Second Syrian War](/source/Syrian_Wars), [Ptolemy II](/source/Ptolemy_II_Philadelphus) loses ground in [Cilicia](/source/Cilicia), [Pamphylia](/source/Pamphylia), and [Ionia](/source/Ionia), while [Antiochus II](/source/Antiochus_II_Theos) regains [Miletus](/source/Miletus) and [Ephesus](/source/Ephesus). A peace is then concluded between Antiochus and Ptolemy under which Antiochus is to marry Ptolemy's daughter [Berenice Syra](/source/Berenice_(Seleucid_queen)).[3]

#### Bactria

- [Diodotus I](/source/Diodotus_I), [Seleucid](/source/Seleucid) [satrap](/source/Satrap) of [Bactria](/source/Bactria), rebels against Antiochus II and becomes the founder of the [Greco-Bactrian Kingdom](/source/Greco-Bactrian_Kingdom).[4]

#### China

- [King Hui of Zhou](/source/Duke_Wen_of_Eastern_Zhou) becomes the last claimant king of the [Zhou dynasty](/source/Zhou_dynasty) of [China](/source/China).[5]
