What place is also known as 'Lacedaemon' in ancient Greece?

Sparta (Doric Greek: Σπάρτα, Spártā; Attic Greek: Σπάρτη, Spártē) was a prominent city-state in Laconia, in ancient Greece. In antiquity, the city-state was known as Lacedaemon (Λακεδαίμων, Lakedaímōn), while the name Sparta referred to its main settlement on the banks of the Eurotas River in Laconia, in south-eastern Peloponnese. Around 650 BCE, it rose to become the dominant military land-power in ancient Greece.

Given its military pre-eminence, Sparta was recognized as the leading force of the unified Greek military during the Greco-Persian Wars, in rivalry with the rising naval power of Athens. Sparta was the principal enemy of Athens during the Peloponnesian War (between 431 and 404 BCE), from which it emerged victorious after the Battle of Aegospotami.

The decisive Battle of Leuctra in 371 BCE ended the Spartan hegemony, although the city-state maintained its political independence until the Roman conquest of Greece in 146 BCE. After the division of the Roman Empire, Sparta underwent a long period of decline, especially in the Middle Ages, when many of its citizens moved to Mystras. Modern Sparta is the capital of the southern Greek region of Laconia and a center for processing citrus and olives.

Sparta was unique in ancient Greece for its social system and constitution, which were supposedly introduced by the semi-mythical legislator Lycurgus. His laws configured the Spartan society to maximize military proficiency.
