The main war that Thucydides describes is between the Athenian Empire and the Peloponnesian League, but there is another, even larger conflict that rages throughout: a class war between the aristocratic class and the new class of plutocrats.
In democratic Athens the plutocrats, wealthy commercial men like Cleon the leather merchant and Nicias the silver mine magnate, are in charge. There is a direct relationship between wealth and political power. The Athenians have found democracy so much to their liking that they have forced most of their colonies and client states to adopt democracy on the Athenian model.In Sparta the situation is very different. The old military class, the Hómoioi or “Peers”, has relaxed a bit from the iron discipline handed down from Lycurgus, but they still rule. Sparta is an oligopoly and her leaders are born into a life devoted to the service of the state. When they speak of their fight for “freedom” they are generally referring to the freedom to no be forced into the Athenian system.
In the rest of the Hellenic world, there is still open conflict between the forces of democracy and oligopoly. In many cities, the two factions are perpetually on the verge of civil war–a situation which both the Athenians and Spartans happily exploit. In the smoldering trouble-spot of Corcyra, for example, the democratic faction has recently seized control and a group exiled aristocrats have been waging a guerrilla war on their own people, becoming little better than pirates. Now, in Book III, the Corcyran situation reaches a moment of crises and a chaotic revolution breaks out. The democratic faction called for help and Athens sends ships. However, a nearby Spartan force also hears of the chaos and sails to Corcyra to aid their own partisans. A confusing battle results in which the Spartans come our somewhat ahead but decide to withdraw. The democratic faction uses the confusion of the battle to slaughter all of the remaining aristocrats and the city briefly descended into anarchy as men grasped the opportunity to eliminate private enemies.
According to Thucydides, the Corcyran revolt is the first of many over the next few years,
So bloody was the march of the revolution, and the impression which it made was the greater as it was one of the first to occur. Later on, one may say, the whole Hellenic world was convulsed; struggles being every where made by the popular chiefs to bring in the Athenians, and by the oligarchs to introduce the Lacedaemonians. In peace there would have been neither the pretext nor the wish to make such an invitation; but in war, with an alliance always at the command of either faction for the hurt of their adversaries and their own corresponding advantage, opportunities for bringing in the foreigner were never wanting to the revolutionary parties.
Revolution thus ran its course from city to city, and the places which it arrived at last, from having heard what had been done before, carried to a still greater excess the refinement of their inventions, as manifested in the cunning of their enterprises and the atrocity of their reprisals.
Political affiliations become even more important than ties of blood, but politics are based on a desire to cease power that could not have been satisfied if the whole ecumene were not in the grips of war. While the various revolutionary leaders might espouse the causes of either democracy or oligarchy, all are mainly motivated by personal greed and ambition.
Class warfare was hardly a new phenomenon in Greece. The Athenian democracy itself had been born from the reforms of Solon, a compromise intended to restore order after a massive wealth imbalance had created intolerable tensions between the commoners and aristocrats,
Now, in the 4th century, there is no compromise. The plutocrats and oligarchs fight it out. Eventually, the oligarchs win, but only after impoverishing themselves so much in wealth and numbers that the whole country is easy prey for the Macedonian conquest a few generations later. The first great age of democracy ends with the Peloponnesian war and the world will not see another true democracy until the Renaissance.
The poor, finding their situation worse with each year–the government and the army in the hands of their masters, and the corrupt courts deciding against them–began to talk of a violent revolt, and a thoroughgoing redistribution of wealth. The rich, unable any longer to collect the debts legally due them, and angry at the challenges to their savings and property, invoked ancient laws and prepared to defend themselves by force against a mob that seemed to threaten not only property but all established order, all religion, and all civilization.” Durant, The Life of Greece p. 112
Class conflict never truly stopped, however, rising to the forefront of history whenever real or perceived inequalities became too extreme. As I continue these notes on the Great Books, we will see that many of the Great Thinkers wrote about social class, class consciousness, and class warfare; these concepts seem critical to any understanding of civilization itself.
Nowadays, as has periodically been the case, Western society is again under extreme social tension because of wealth inequality between plutocrats and proletarians, to say nothing of the reactionary flailings of a bourgeoisie feeling a marked decrease in its size and influence. Perhaps studying history in the form of the Great Books will hold the key to finding a wise compromise like the reforms of Solon, rather than plunging our society into decades of internecine warfare and revolution like the Peloponnesian Wars.
