Messenia (ancient region) in the context of "Crypteia"

Sparta was a prominent city-state in Laconia in ancient Greece. In 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. Around 650 BC, it rose to become one of the major military powers in Greece, a status it retained until 371 BC.

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 (431–404 BC), from which it emerged victorious after the Battle of Aegospotami. Thebes' victory over Sparta at the Battle of Leuctra in 371 BC ended Spartan hegemony and freed Messenia from Spartan rule; the loss of the slave labor this region provided sent the city into terminal decline as a military power, though it retained its independence until its forcible integration into the Achaean League in 192 BC. The city recovered some autonomy after the Roman conquest of Greece in 146 BC and became a tourist destination during the Roman era, restoring some measure of prosperity. However, Sparta was sacked in 396 AD by the Visigothic king Alaric, and underwent a long period of decline into the medieval period, when much of its population relocated to Mystras. Modern Sparta is a provincial town and the seat of the Laconia regional administration.

Description of Greece (Ancient Greek: Ἑλλάδος Περιήγησις, romanized: Helládos Periḗgēsis) is the only surviving work by the ancient "geographer" or tourist Pausanias (c. 110 – c. 180).

Pausanias' Description of Greece comprises ten books, each of them dedicated to some part of mainland Greece. He is essentially describing his own travels, and large parts of Greece are not covered, including the islands. His tour begins in Attica (Ἀττικά) and continues with Athens, including its suburbs or demes. Then the work goes with Corinthia (Κορινθιακά), Laconia (Λακωνικά), Messenia (Μεσσηνιακά), Elis (Ἠλιακά), Achaea (Ἀχαϊκά), Arcadia (Ἀρκαδικά), Boeotia (Βοιωτικά), Phocis (Φωκικά), and Ozolian Locris (Λοκρῶν Ὀζόλων).

Doric or Dorian (Ancient Greek: Δωρισμός, romanized: Dōrismós), also known as West Greek, was a group of Ancient Greek dialects; its varieties are divided into the Doric proper and Northwest Doric subgroups. Doric was spoken in a vast area, including northern Greece (Acarnania, Aetolia, Epirus, western and eastern Locris, Phocis, Doris, and possibly Lower Macedonia and Upper Macedonia), most of the Peloponnese (Achaea, Elis, Messenia, Laconia, Argolid, Aegina, Corinthia, and Megara), the Southern Aegean (Kythira, Milos, Thera, Crete, Karpathos, and Rhodes), as well as the colonies of some of those regions in Cyrene, Magna Graecia, the Black Sea, the Ionian Sea and the Adriatic Sea. It was also spoken in the Greek sanctuaries of Dodona, Delphi, and Olympia, as well as at the four Panhellenic festivals; the Isthmian, Nemean, Pythian, and Olympic Games.

By Hellenistic times, under the Achaean League, an Achaean Doric koine appeared, exhibiting many peculiarities common to all Doric dialects, which delayed the spread of the Attic-based Koine Greek to the Peloponnese until the 2nd century BC. The only living descendant of Doric is the Tsakonian language which is still spoken in Greece today; though critically endangered, with only a few hundred – mostly elderly – fluent speakers left.

The Battle of Mantinea was fought on 4 July 362 BC between the Thebans, led by Epaminondas and supported by the Arcadians, Argives, Messenians, Thessalians, Euboeans and the Boeotian league against the Spartans, Eleans, Athenians, and Mantineans. The battle was to determine which of the two alliances would dominate Greece. However, the death of Epaminondas and his intended successors would cost Thebes the military leadership and initiative to maintain Theban supremacy in the region. Similarly, the Spartans were weakened by yet another defeat and loss of troops. Epaminondas' death coupled with the impact on the Spartans of yet another defeat weakened both alliances, and paved the way for Macedonian conquest led by Philip II of Macedon.
