Ancient Greece to the End of the Peloponnesian Wars37They could hold land in their own right and were capa-
ble of dealing with hostile and rebellious helots. Their
courage, like that of the Spartan men, was legendary.
In spite of their military virtues, the Spartans were
not an aggressive power until late in their history. The
constant threat of helot insurrection made them wary
of foreign entanglements, and Spartan policy was tradi-
tionally defensive and inward-looking. This changed in
the course of the fifth century B.C. when the Persian in-
vasion and the subsequent expansion of Athens forced
them to take a more active role. They would eventually
be drawn into a fatal rivalry with the Athenians, whose
army was inferior but whose superior navy and greater
wealth made them formidable antagonists. The story of
those struggles forms the political background of the
Greek classical age.
The Persian War
The Greeks developed their unique civilization in large
part because for centuries they were isolated from the
turbulent politics of the Asian land mass. That isolation
came to an abrupt end in the Persian War of 499–479
B.C. (see map 2.1). The tiny states whose competition
with one another had long since become traditional
now faced the greatest military power the world had
yet known.
The Persians were an Indo-European people from
the Iranian highlands who emerged in the sixth century
B.C. as the dominant power in the vast region between
Mesopotamia and India. By the end of the sixth century
B.C. the ruling elite had adopted Zoroastrianism, a reli-
gion preached by the prophet and reformer Zoroaster0 100 200 Miles0 100 200 300 KilometersWALLSLONGPHALERUM WALLACROPOLISPIRAEUSCephisusSaronicGulf0 1 2 Miles0 1 2 3 Kilometers
