Key idea: The history of the war between Sparta and Athens. As Thucydides said he, "an Athenian, wrote the history of the war between the Peloponnesians and the Athenians, beginning at the moment that it broke out". He was able to get the information from the eye-witnesses as well as from his own experience.
The richest soils were always most subject to this change of masters; such as the district now called Thessaly, Boeotia, most of the Peloponnese, Arcadia excepted, and the most fertile parts of the rest of Hellas.
The goodness of the land favoured the aggrandizement of particular individuals, and thus created faction which proved a fertile source of ruin. It also invited invasion...
As the power of Hellas grew, and the acquisition of wealth became more an object, the revenues of the states increasing, tyrannies were by their means established almost everywhere
The Athenians and Peloponnesians had these antecedent grounds of complaint against each other: the complaint of Corinth was that her colony of Potidaea, and Corinthian and Peloponnesian citizens within it, were being besieged;
that of Athens against the Peloponnesians that they had incited a town of hers, a member of her alliance and a contributor to her revenue, to revolt, and had come and were openly fighting against her on the side of the Potidaeans.
For all this, war had not yet broken out: there was still truce for a while; for this was a private enterprise on the part of Corinth.
The allies of Lacedaemon
These were the allies of Lacedaemon: all the Peloponnesians within the Isthmus except the Argives and Achaeans, who were neutral; Pellene being the only Achaean city that first joined in the war, though her example was afterwards followed by the rest. Outside Peloponnese the Megarians, Locrians, Boeotians, Phocians, Ambraciots, Leucadians, and Anactorians. Of these, ships were furnished by the Corinthians, Megarians, Sicyonians, Pellenians, Eleans, Ambraciots, and Leucadians; and cavalry by the Boeotians, Phocians, and Locrians. The other states sent infantry. This was the Lacedaemonian confederacy.
The allies of Athens
That of Athens comprised the Chians, Lesbians, Plataeans, the Messenians in Naupactus, most of the Acarnanians, the Corcyraeans, Zacynthians, and some tributary cities in the following countries, viz., Caria upon the sea with her Dorian neighbours, Ionia, the Hellespont, the Thracian towns, the islands lying between Peloponnese and Crete towards the east, and all the Cyclades except Melos and Thera. Of these, ships were furnished by Chios, Lesbos, and Corcyra, infantry and money by the rest. Such were the allies of either party and their resources for the war.
In the same winter the Athenians gave a funeral at the public cost to those who had first fallen in this war... and Pericles, son of Xanthippus, was chosen to pronounce their eulogium.
Our constitution does not copy the laws of neighbouring states; we are rather a pattern to others. han imitators ourselves. Its administration favours the many instead of the few; this is why it is called a democracy.
If we look to the laws, they afford equal justice to all in their private differences; if no social standing, advancement in public life falls to reputation for capacity, class considerations not being allowed to interfere with merit; nor again does poverty bar the way, if a man is able to serve the state, he is not hindered by the obscurity of his condition.
The freedom which we enjoy in our government extends also to our ordinary life.
There, far from exercising a jealous surveillance over each other, we do not feel called upon to be angry with our neighbour for doing what he likes, or even to indulge in those injurious looks which cannot fail to be offensive, although they inflict no positive penalty.
But all this ease in our private relations does not make us lawless as citizens. Against this fear is our chief safeguard, teaching us to obey the magistrates and the laws, particularly such as regard the protection of the injured, whether they are actually on the statute book, or belong to that code which, although unwritten, yet cannot be broken without acknowledged disgrace...
Further, we provide plenty of means for the mind to refresh itself from business. We celebrate games and sacrifices all the year round, and the elegance of our private establishments forms a daily source of pleasure and helps to banish the spleen...
If we turn to our military policy, there also we differ from our antagonists. We throw open our city to the world, and never by alien acts exclude foreigners from any opportunity of learning or observing, although the eyes of an enemy may occasionally profit by our liberality; trusting less in system and policy than to the native spirit of our citizens; while in education, where our rivals from their very cradles by a painful discipline seek after manliness, at Athens we live exactly as we please, and yet are just as ready to encounter every legitimate danger.
Nor are these the only points in which our city is worthy of admiration. We cultivate refinement without extravagance and knowledge without effeminacy; wealth we employ more for use than for show, and place the real disgrace of poverty not in owning to the fact but in declining the struggle against it.
Our public men have, besides politics, their private affairs to attend to, and our ordinary citizens, though occupied with the pursuits of industry, are still fair judges of public matters; for, unlike any other nation, regarding him who takes no part in these duties not as unambitious but as useless, we Athenians are able to judge at all events if we cannot originate, and, instead of looking on discussion as a stumbling-block in the way of action, we think it an indispensable preliminary to any wise action at all...
As soon as it was day Nicias put his army in motion, pressed, as before, by the Syracusans and their allies, pelted from every side by their missiles, and struck down by their javelins. The Athenians pushed on for the Assinarus, impelled by the attacks made upon them from every side by a numerous cavalry and the swarm of other arms, fancying that they should breathe more freely if once across the river, and driven on also by their exhaustion and craving for water.
Once there they rushed in, and all order was at an end, each man wanting to cross first, and the attacks of the enemy making it difficult to cross at all; forced to huddle together, they fell against and trod down one another, some dying immediately upon the javelins, others getting entangled together and stumbling over the articles of baggage, without being able to rise again.
Meanwhile the opposite bank, which was steep, was lined by the Syracusans, who showered missiles down upon the Athenians, most of them drinking greedily and heaped together in disorder in the hollow bed of the river. The Peloponnesians also came down and butchered them, especially those in the water, which was thus immediately spoiled, but which they went on drinking just the same, mud and all, bloody as it was, most even fighting to have it.
At last, when many dead now lay piled one upon another in the stream, and part of the army had been destroyed at the river, and the few that escaped from thence cut off by the cavalry, Nicias surrendered himself to Gylippus, whom he trusted more than he did the Syracusans, and told him and the Lacedaemonians to do what they liked with him, but to stop the slaughter of the soldiers...
This was the greatest Hellenic achievement of any in thig war, or, in my opinion, in Hellenic history; at once most glorious to the victors, and most calamitous to the conquered. They were beaten at all points and altogether; all that they suffered was great; they were destroyed, as the saying is, with a total destruction, their fleet, their army, everything was destroyed, and few out of many returned home. Such were the events in Sicily.
