Roman expansion in Italy from 500 BC to 218 BC through the Latin War (light red), Samnite Wars (pink/orange), Pyrrhic War (beige), and First and Second Punic War (yellow and green). The Roman Republic in 290 BC is marked with dark and light red, pink and orange.
Year 290 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Rufinus and Dentatus (or, less frequently, year 464 Ab urbe condita). The denomination 290 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.
