Langarus (Greek: Λάγγαρος; died 335 BC), king of the Agrianians, was a contemporary of Alexander the Great (336–323 BC), with whom he ingratiated himself even before the death of Philip II, previous king of Macedon. He rendered Alexander important services shortly after his accession, in his expedition against the Illyrians and Taulantians, when the Autariatae were preparing to attack him on his march. Langarus by an invasion of their territory prevented them from carrying their purpose into effect. Alexander conferred on him the most distinguished marks of his regard and favour, and promised him his half-sister Cynane in marriage; but Langarus died soon after his return home.[1]
