No means were found of reconciling the two parties: the rich could not persuade themselves to surrender their property; the poor were unwilling to die of hunger. According to Aristotle all revolutions have their origin in the distribution of wealth. "Every civil war," says Polybius, "is initiated to subvert wealth."

They fought savagely, as is always the case between neighbors. "At Miletus the poor were at first predominant and forced the rich to flee the city. But afterwards, regretting that they had not killed them all, they took the children of the exiles, assembled them in barns and had them trodden under the feet of cattle. The rich reëntered the city and became masters of it. In their turn they seized the children of the poor, coated them with pitch, and burned them alive."

Democracy and Oligarchy.—Each of the two parties—rich and poor—had its favorite form of government and set it in operation when the party held the city. The party of the rich was the Oligarchy which gave the government into the hands of a few people. That of the poor was the Democracy which gave the power to an assembly of the people. Each of the two parties maintained an understanding with the similar party in the other cities. Thus were formed two leagues which divided all the Greek cities: the league of the rich, or Oligarchy, the league of the poor, or Democracy. This régime began during the Peloponnesian War. Athens supported the democratic party, Sparta the oligarchic. The cities in which the poor had the sovereignty allied themselves with Athens; the cities where the rich governed, with Sparta. Thus at Samos when the poor gained supremacy they slew two hundred of the rich, exiled four hundred of them, and confiscated their lands and houses. Samos then adopted a democratic government and allied itself with Athens. The Spartan army came to besiege Samos, bringing with it the rich exiles of Samos who wished to return to the city by force. The city was captured, set up an oligarchy, and joined the league of Sparta.

The Tyrants.—At length, the poor perceived that the democratic form of government did not give them strength enough to maintain the contest. In most of the cities they consented to receive a chief. This chief was called Tyrant. He governed as master without obeying any law, condemning to death, and confiscating property at will. Mercenaries defended him against his enemies. The following anecdote represents the policy of the tyrants: "Periander, tyrant of Corinth, sent one day to Thrasybulus, tyrant of Miletus, to ask what conduct he ought to follow in order to govern with safety. Thrasybulus led the envoy into the field end walked with him through the wheat, striking off with his staff all heads that were higher than the others. He sent off the envoy without further advice." The messenger took him for a fool, but Periander understood: Thrasybulus was counselling him to slay the principal citizens.

Everywhere the rich were killed by the tyrant and their goods confiscated; often the wealth was distributed among the poor. This is why the populace always sustained the tyrant.

There were tyrants in Greece from the sixth century; some, like Pisistratus, Polycrates, and Pittacus, were respected for their wisdom. At that time every man was called tyrant who exercised absolute power outside the limits of the constitution; it was not a title of reproach.

But when the tyrants made incessant warfare on the rich they became sanguinary and so were detested. Their situation is depicted in the famous story of Damocles. This Damocles said to Dionysius, tyrant of Syracuse, "You are the happiest of men." "I will show you the delight of being a tyrant," replied Dionysius. He had Damocles served with a sumptuous feast and ordered his servants to show the guest the same honors as to himself. During the feast Damocles raised his eyes and perceived a sword suspended to the ceiling held only by a horse hair, and hanging directly over his head. The comparison was a striking one—the tyrant's life hung only by a thread. The rich, his enemies, watched for an opportunity to cut it, for it was regarded as praiseworthy to assassinate a tyrant. This danger irritated him and made him suspicious and cruel. He dared not trust anybody, believed himself secure only after the massacre of all his enemies, and condemned the citizens to death on the slightest suspicion. Thus the name tyrant became a synonym of injustice.

Exhaustion of Greece.—The civil wars between rich and poor continued for nearly three centuries (430-150 B.C.). Many citizens were massacred, a greater number exiled. These exiles wandered about in poverty. Knowing no trade but that of a soldier, they entered as mercenaries into the armies of Sparta, Athens, the Great King, the Persian satraps—in short, of anybody who would hire them. There were 50,000 Greeks in the service of Darius against Alexander. It was seldom that such men returned to their own country.

Thus the cities lost their people. At the same time families became smaller, many men preferring not to marry or raise children, others having but one or two. "Is not this," says Polybius, "the root of the evil, that of these two children war or sickness removes one, then the home becomes deserted and the city enfeebled?" A time came when there were no longer enough citizens in the towns to resist a conqueror.
