The Euboian League was a short-lived federal alliance formed among the cities of Euboea — principally Chalkis, Eretria, and Histiaia — following the expulsion of Spartan influence from the island around 378–377 BC. Athenian backing made the league possible, but that dependency created its own tensions. The alliance collapsed entirely after the Battle of Mantinea in 362 BC weakened Athenian regional authority, and Philip II's campaigns through northern Greece delivered the final blow by 357 BC.

Federal coinage of this type is rare relative to the individual city issues that preceded and followed it. The BCD specimen cited in the Copenhagen corpus represents one of the better-documented die linkages for the series.
