With the cessation of political life and the establishment of the universal monarchy, the nationality and the distinctive civilisation of the separate districts are restricted to religion, which has become theology. The development of oriental civilisation then subsides in the competition of these religions and the unavoidable coalescence consequent thereupon. This is true even of that nation which experienced the richest intellectual development, and did the most important work of all oriental peoples—the Israelites. When the great political storms from which the universal monarchy arose have spent their rage, Israel, the nation, has developed into Judaism; and under the Persian rule and with the help of the kingdom it organises itself as a church which seeks to put an end to all free individual movement, upon which the greatness of ancient Israel rests.
It was just the same with the ruling nation, the Persians, however vigorous their entrance into history under Cyrus. The Persian kingdom is, indeed, a civilised state, but the civilisations that it includes lack the highest that a civilisation can offer: an energetic, independent life, a combination of the firm institutions and permanent attainments of the past with the free, progressive, and creative movement of individuality. So the East, after the Persian period, was unable of its own force to create anything new. It stagnated, and, had it not received new elements from without, had it been left permanently to itself, would perhaps in the course of centuries have altered its external form again and again, but would hardly have produced anything new or have progressed a step beyond what had already been attained.
But when Cyrus and Darius founded the Persian kingdom, the East no longer stood alone. The nations and kingdoms of the East came into communication with the coast of the Mediterranean very early—not later than the beginning of the second millennium B.C.; and under their influence, about 1500 B.C., a civilisation arose among the Greeks bordering the Ægean. We call it the Mycenæan, and in spite of its formal dependence upon the East it could, in the field of art (where alone we have an exact knowledge of it), take an independent and equal place beside the great civilisations of the East.
How Greek civilisation continued to advance from step to step for many centuries in the field of politics and society as well as in that of the intellect; how it spread simultaneously over all the islands and coasts of the Mediterranean, from Massalia on the coast of the Ligurians and Cumæ in the land of the Oscans to the Crimea and the eastern coast of the Black Sea, and in the south as far as Cyprus and Cilicia; how Greek culture at the same time took root in much more remote districts, especially in Asia Minor; and how under its influence an energetic civilisation arose among the tribes of Italy, cannot be depicted here.
When the Persian kingdom was founded the Hellenes had developed from a group of linguistically related tribes into a nation possessing a completely independent culture whose equal the world had never yet seen, a culture whose mainspring was that very political and intellectual freedom of the individual which was completely lacking in the East.
Hence its character was purely human, its aim the complete and harmonious development of man; and if for that very reason it always strove to be moderate and to adapt itself to the moral and cosmical forces that govern human life, nevertheless it could accomplish this only in free subordination, by absorbing the moral commandment into its own will. Therefore it did not permit the opposing theological tendencies to gain control, strong as was their development in considerable districts of Greece in the sixth century. At that very period, on the other hand, it was stretching out to grasp the apples on the tree of knowledge; in the most advanced regions of Hellas science and philosophy were opposing theology. National as it was, this culture lacked but one thing: the political unity of the nation, the co-ordination of all its powers in the vigorous organism of a great state.
The instinct of freedom itself, upon which the greatness of this civilisation rested, favoured by the geographical conformation of the Greek soil, had caused a constantly increasing political disunion, which saw in the complete and unlimited autonomy of every individual community, even of the tiniest of the hundreds of city states into which Hellas was divided, the highest ideal of liberty, the only fit existence for a Hellene. And, internally, every one of these dwarf states was eaten by the canker of political and social contrasts which could not be permanently suppressed by any attempt to introduce a just political order founded upon a codified law and a written constitution—whether the ideal were the rule of the “best,” the rule of the whole, i.e. of the actual masses, or that of a mixed constitution. The smaller the city and its territory, the more apt were these attempts to become bloody revolutions. Lively as was the public spirit, clearly as the justice of the demand for subordination to law was recognised, every individual and every party interpreted it according to its own conception and its own judgment, and at all times there were not a few who were ready to seize for themselves all that the moment offered.
To be sure, manifold and successful attempts to found a greater political power were brought about by the advancing growth of industry and culture, as well as by the development of the citizen army of hoplites, which had a firm tactical structure and was well schooled in the art of war. In the Peloponnesus Sparta brought the whole south under the rule of its citizens and not only effected the union of almost the whole peninsula into a league, but established its right, as the first military power of Hellas, to leadership in all common affairs.
In middle Greece, Thebes succeeded in uniting Bœotia into a federal state, while its neighbour Athens, which had maintained the unity of the Attic district since the beginning of history, began to annex the neighbouring districts of Megara, Bœotia, and Eubœa, and laid the foundation of a colonial power, as Corinth had formerly done. In the north the Thessalians acquired leadership over all surrounding tribes. In the west, in Sicily, usurpers had founded larger monarchical unified states, especially in Syracuse and Agrigentum.
But all these combinations were after all only of very limited extent and by no means firmly united; on the contrary, the weaker communities felt even the loosest kind of federation, to say nothing of dependence, as an oppressive fetter which impaired the ideal of the individual destiny of the autonomous state, and which at least one party,—generally the one that happened to be out of power,—felt justified in bursting at the first opportunity.
However, as things lay, the nation found itself forced, with this sort of constitution, to take up the struggle for its political independence. The Greeks of Asia Minor, formerly subjects of the kings of Sardis, had become subjects of the Persian kingdom under Cyrus; the free Hellenes had the most varied relations with the latter, and more than once gave him occasion to intervene in their affairs. The Persian kingdom, which under Darius no longer attempted conquests that were not necessary for the maintenance of its own existence, took no advantage of these provocations until the revolt of the Greeks of Asia Minor, supported by Athens, made war inevitable.
After the first attempt had failed Xerxes repeated it on the greatest scale. Against the Hellenic nation, whose alien character was everywhere a hindrance in its path, the Orient arose in the east and the west for a decisive struggle; the Phœnician city of Carthage, the great sea power of the west, was in alliance with the Persian kingdom. Only the minority of the Hellenes joined in the defence; in the west the princes of Syracuse and Agrigentum, in the east Sparta and the Peloponnesian league, Athens, the cities of Eubœa and a few smaller powers. But in both fields of operation the Hellenes won a complete victory; the Carthaginians were defeated on the Himera, in the east Themistocles broke the base of the Persian position by destroying their sea power with the Athenian fleet that he had created, and on the battle-field of Platæa the Persian land forces were defeated by the superiority of the Greek armies of hoplites.
