Sparta was a prominent ancient Greek polis in Laconia. In classical antiquity, the state was known as Lacedaemon (Λακεδαίμων, Lakedaímōn), while Sparta referred to its capital, a group of villages in the valley of the Evrotas River in Laconia, in southeastern Peloponnese. During the 7th century BC, it rose to become the most prominent land military power in the Greek world, a status it retained until its defeat at Leuctra in 371 BC. In the 6th century BC Sparta founded the Peloponnesian League, establishing its hegemony over most of Peloponnese. During the second Persian invasion of Greece, Sparta was recognised as the leading land force of the Hellenic alliance that also included the rising maritime power of Athens. The Spartan army was crucial in the battles of Thermopylae and Plataea under the leadership of Leonidas and Pausanias respectively. Sparta led the Peloponnesian League against the Athenian Empire during the Peloponnesian War (431–404 BC), from which it emerged victorious after Lysander's victory at the naval Battle of Aegospotami.
