The Sacred Band of Carthage is the name used by Greek historians to refer to an infantry unit of Carthaginian foot citizens that served in Carthaginian armies during the fourth century BC. The presence of Carthaginian citizens fighting as infantry in these armies is unusual as Carthaginian citizens usually only served as officers or cavalry in the Carthaginian armed forces and the bulk of Carthaginian armies were usually made up of mercenaries, infantry from allied communities (who might be Punic colonists) and subject levies.
