Spartan hegemony

The polis of Sparta was the greatest military land power of classical Greek antiquity. During the classical period, Sparta governed, dominated or influenced the entire Peloponnese. Additionally, the defeat of the Athenians and the Delian League in the Peloponnesian War in 431-404 BCE resulted in a short-lived Spartan dominance of the Greek world from 404 to 371 BCE. Due to their mistrust of others, Spartans discouraged the creation of records about their internal affairs. The only histories of Sparta are from the writings of Xenophon, Thucydides, Herodotus and Plutarch, none of whom were Spartans. Plutarch was writing several centuries after the period of Spartan hegemony had ceased. This creates difficulties in understanding the Spartan political system, which was distinctly different from any other Greek polis.
