Greek Unity: Federation against Barbarians
Beyond the family and city-state, the third concentric circle of kinship and loyalty is that of the league of cities or indeed the Greek nation itself. In the Republic, Plato had argued that Greeks should be gentle with one another on account of their shared blood, limiting their engagement in all-out warfare and enslavement to conflicts with barbarians. In the Laws, Plato returns to this theme, praising the federation of Greek city-states against foreign invasion.
After the family, the collection of families, and the city-state “being founded in succession over a vast period,” finally “we discover this fourth state” (683a), the generally loose and fractious leagues or confederations of Greek city-states as a potentially even higher form of social organization.
Plato discusses the mythical history of three city-states founded by the descendants of Hercules — Sparta, Argos, and Messene — which had together formed the Dorian League. The confederation was meant to protect not just themselves but the Greek nation itself:
Well then, it’s pretty obvious that they intended the arrangements they made to protect adequately not only the Peloponnese but the Greeks in general against any possible attack by non-Greeks — as for example occurred when those who then lived in the territory of Ilium trusted to the power of the Assyrian empire, which Ninos had founded, and provoked the war against Troy by their arrogance. You see, a good deal of the splendor of the Assyrian empire still remained, and the dread of its united organization was the counterpart in that age of our fear of the Great King of Persia today. Troy, which was part of the Assyrian empire, had been captured a second time [as recounted in the Iliad]. To meet such dangers the Dorian army formed a single unified body, although at that period it was distributed among the three states under the command of the kings (who were brothers, being sons of Hercules). (685b–d)
Plato laments however that the Dorian League was short-lived, despite the fact that all three cities were ruled by brothers: “if they had done as they intended and had agreed a common policy, their power would have been irresistible, militarily speaking” (686b). Read more
