Battle of Leuctra in the context of "Sparta"

The Theban hegemony lasted from the Theban victory over the Spartans at Leuctra in 371 BC to another victory over the Spartans at Mantinea in 362 BC, which was, however, indecisive and greatly weakened both sides. Still, Thebes sought to maintain its position until finally eclipsed by the rising power of Macedon in 335 BC.

Externally, the way was paved for Theban ascendancy by the collapse of Athenian power in the Peloponnesian War (431–404 BC), through the weakening of the Spartans by their oliganthropia (demographic decline) and by the inconclusive Corinthian War (395–386 BC). Internally, the Thebans enjoyed two temporary military advantages:

Epaminondas (/ɪˌpæmɪˈnɒndəs/; Ancient Greek: Ἐπαμεινώνδας, romanized: Epameinōndas; 419/411–362 BC) was a Greek general and statesman of the 4th century BC who transformed the Ancient Greek city-state of Thebes, leading it out of Spartan subjugation into a pre-eminent position in Greek politics called the Theban Hegemony. In the process, he broke Spartan military power with his victory at Leuctra and liberated the Messenian helots, a group of Peloponnesian Greeks who had been enslaved under Spartan rule for some 230 years following their defeat in the Second Messenian War ending in 600 BC. Epaminondas reshaped the political map of Greece, fragmented old alliances, created new ones, and supervised the construction of entire cities. He was also militarily influential and invented and implemented several important battlefield tactics, such as the oblique order.

Xenophon, the historian and contemporary, is the main source for Epaminondas's military prowess, and Xenophon describes his admiration for him in his major work Hellenica (book VII, chap. 5, 19). Accordingly, in later centuries the Roman orator Cicero called him "the first man of Greece", and in more recent times Michel de Montaigne judged him one of the three "worthiest and most excellent men" who had ever lived. The changes Epaminondas wrought on the Greek political order did not long outlive him, as the cycle of shifting hegemonies and alliances continued unabated. A mere twenty-seven years after his death, a recalcitrant Thebes was obliterated by Alexander the Great. Thus Epaminondas—who had been praised in his time as an idealist and liberator—is today largely remembered for a decade (371 BC to 362 BC) of campaigning that established a decade long Theban hegemony but also sapped the strength of the great city-states and paved the way for Macedonian hegemony.

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.

The history of Sparta describes the history of the ancient Doric Greek city-state known as Sparta from its beginning in the legendary period to its incorporation into the Achaean League under the late Roman Republic, as Allied State, in 146 BC, a period of roughly 1000 years. Since the Dorians were not the first to settle the valley of the Eurotas River in the Peloponnesus of Greece, the preceding Mycenaean and Stone Age periods are described as well. Sparta went on to become a district of modern Greece. Brief mention is made of events in the post-classical periods.

Dorian Sparta rose to dominance in the 6th century BC. At the time of the Persian Wars, it was the recognized leader by assent of the Greek city-states. It subsequently lost that assent through suspicion that the Athenians were plotting to break up the Spartan state after an earthquake destroyed Sparta in 464 BC. When Sparta defeated Athens in the Peloponnesian War, it secured an unrivaled hegemony over southern Greece. Sparta's supremacy was broken following the Battle of Leuctra in 371 BC. It was never able to regain its military superiority and was finally absorbed by the Achaean League in the 2nd century BC.

Leuctra or Leuktra (Ancient Greek: τὰ Λεῦκτρα, romanized: tà Leûktra, Attic Greek pronunciation: [tà lêu̯k.tra] or τὸ Λεῦκτρον, tò Leûktron [tò lêu̯k.tron]) was a village in ancient Boeotia, situated on the road from Thespiae to Plataea, and within the territory of the former city. Leuctra is most notable for the Battle of Leuctra, fought in its neighbourhood between the Spartans and Thebans in 371 BCE, by which the supremacy of Sparta was demolished. In the plain of Leuctra, was the tomb of the two daughters of Scedasus, a Leuctrian. The daughters were violated by Spartans, and had afterwards slain themselves. Before the battle, Epaminondas crowned the tomb with wreaths, fulfilling an oracle's prophecy that the Spartans would be defeated at this spot.

The site of Leuctra is near the modern village of Lefktra, renamed to reflect to connection with the ancient place.

The Theban–Spartan War of 378–362 BC was a series of military conflicts fought between Sparta and Thebes for hegemony over Greece. In 378 BC, led by General Epaminondas, Thebes revolted against its Spartan garrison and successfully repelled Spartan offensives. A clever tactician, Epaminondas crushed the hitherto invincible Spartan army at Leuctra in 371 BC, therefore ending Sparta's hegemony and starting Thebes' own hegemony over Greece. After Leuctra, the war continued in the Peloponnese, where Sparta was fighting for survival. In 362 BC, the Battle of Mantinea was a new victory for Thebes, but Epaminondas was also killed. The conflict ended soon after with a treaty of general peace signed by all the belligerents, except Sparta, which was by now isolated and permanently weakened.
