Year 459 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Vibulanus and Uritinus (or, less frequently, year 295 Ab urbe condita). The denomination 459 BC for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
Athens allies itself with the city state of Megara which is under pressure from Corinth. This alliance leads to war between Corinth and Athens. The first battle of the war, at Haliesis in the Gulf of Argolis, results in a Corinthian victory, but the next battle, at Cecryphalea (modern Angistrion), goes Athens' way.
The Aequi occupy Tusculum. In response to the threat, the Roman Senate decide to send an army to help the allied city, under the command of consul Lucius Cornelius Maluginensis. In addition, the consul Fabius Vibulanus, who was at that point besieging Antium, moves his forces to attack Tusculum. The Tusculans are able to recapture their city. A truce is then arranged with the Aequi.
