Agesilaus II was king of Sparta from c. 400 to c. 360 BC. Generally considered the most important king in the history of Sparta, Agesilaus was the main actor during the period of Spartan hegemony that followed the Peloponnesian War. Although brave in combat, Agesilaus lacked the diplomatic skills to preserve Sparta's position, especially against the rising power of Thebes, which reduced Sparta to a secondary power after its victory at Leuctra in 371 BC.
This article concerns the period 399 BC – 390 BC.
Epaminondas 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 Third 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.
The Battle of Leuctra was fought on 6 July 371 BC between the Boeotians led by the Thebans, and the Spartans along with their allies amidst the post–Corinthian War conflict. The battle took place in the vicinity of Leuctra, a village in Boeotia in the territory of Thespiae. The Theban victory shattered Sparta's immense influence over the Greek peninsula, which Sparta had gained with its victory in the Peloponnesian War a generation earlier.
Spartan hegemony refers to the period of dominance by Sparta in Greek affairs from 404 to 371 BC. Even before this period the polis of Sparta was the greatest military land power of classical Greek antiquity and governed, dominated or influenced the entire Peloponnese. The defeat of the Athenians and the Delian League in the Peloponnesian War in 431–404 BC resulted in a short-lived Spartan dominance of the southern Greek world from 404 to 371 BC. 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.
The Sacred Band of Thebes was a troop of select soldiers, consisting of 150 pairs of male lovers which formed the elite force of the Theban army in the 4th century BC, ending Spartan domination. Its predominance began with its crucial role in the Battle of Leuctra in 371 BC. It was annihilated by Philip II of Macedon in the Battle of Chaeronea in 338 BC.
The first Battle of Mantinea was fought in 418 BC during the Peloponnesian War. In this battle, Sparta and its Peloponnesian allies defeated an allied army of Argos, Athens, Mantinea and several others.
Chabrias was an Athenian general active in the first half of the 4th century BC. During his career he was involved in several battles, both on land and sea. The orator Demosthenes described him as one of the most successful commanders Athens ever had:
To sum up the whole: he is the only general who never lost a single city or post or ship or soldier, when he commanded you: none of your enemies has any trophy over you and him, while you have many over many enemies under his command.
The Corinthian War was a conflict in ancient Greece which pitted Sparta against a coalition of city-states comprising Thebes, Athens, Corinth and Argos, backed by the Achaemenid Empire. The war was caused by dissatisfaction with Spartan imperialism in the aftermath of the Peloponnesian War, both from Athens, the defeated side in that conflict, and from Sparta's former allies, Corinth and Thebes, who had not been properly rewarded. Taking advantage of the fact that the Spartan king Agesilaus II was away campaigning in Asia against the Achaemenid Empire, Thebes, Athens, Corinth and Argos forged an alliance in 395 BC with the goal of ending Spartan hegemony over Greece; the allies' war council was located in Corinth, which gave its name to the war. By the end of the conflict, the allies had failed to end Spartan hegemony over Greece, although Sparta was durably weakened by the war.
The Battle of Cnidus was a military operation conducted in 394 BC by the Achaemenid Empire against the Spartan fleet during the Corinthian War. A fleet under the joint command of Pharnabazus and former Athenian admiral, Conon, destroyed the Spartan fleet led by the inexperienced Peisander, ending Sparta's brief bid for naval supremacy.
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, and the Boeotian league against the Spartans, led by King Agesilaus II and supported by the Eleans, Athenians, Euboeans, 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.
Thespiae was an ancient Greek city (polis) in Boeotia. It stood on level ground commanded by the low range of hills which run eastward from the foot of Mount Helicon to Thebes, near modern Thespies.
The Battle of Haliartus was fought in 395 BC between Sparta and Athens. After Athenians' defeat at the Peloponnesian War, Athens tried to recover, but also gained the support of Boeotia. Dissatisfied with this situation, Sparta sent an army against Athens and was defeated by the Athenians and Boeotians. Lysander, one of Sparta's most successful generals, was killed in this battle. Haliartus marked the start of the Corinthian War, which continued until 387 BC.
The Battle of Nemea of 394 BC, also known in ancient Athens as the Battle of Corinth, was a battle in the Corinthian War, between Sparta and the coalition of Argos, Athens, Corinth, and Thebes. The battle was fought in Corinthian territory, at the dry bed of the Nemea River. The battle was a decisive Spartan victory, which, coupled with the Battle of Coronea later in the same year, gave Sparta the advantage in the early fighting on the Greek mainland.
The Battle of Tegyra was an ancient Greek battle between Theban and Spartan hoplite forces. In the battle, a Theban army under Pelopidas was challenged by a substantially larger Spartan force while retreating from an abortive attack on Orchomenus, but successfully attacked and routed the Spartans. The battle marked the first occasion in the historical record in which a Spartan force had been defeated by a numerically inferior enemy in a set battle.
The Arcadian League was a league of city-states in ancient Greece. It combined the various cities of Arcadia, in the Peloponnese, into a single state. The league was founded in 370 BC, taking advantage of the decreased power of Sparta, which had previously dominated and controlled Arcadia. Mantinea, a city that had suffered under Spartan dominance, was particularly prominent in pushing for its founding. The league was responsible for the foundation of Megalopolis.
The Battle of Lechaeum was fought between the Athenians and the Spartans during the Corinthian War; it ended in an Athenian victory. During the battle, the Athenian general Iphicrates took advantage of the situation when a Spartan hoplite regiment operating near Corinth was marching through open terrain without the protection of any missile throwing troops. He decided to ambush it with his force of javelin throwers, or peltasts. By launching repeated hit-and-run attacks against the Spartan formation, Iphicrates and his men were able to wear the Spartans down, eventually routing them and killing just under half. This marked one of the first occasions in Greek military history on which a force of peltasts had defeated a force of hoplite heavy infantry.
The First Peloponnesian War was fought between Sparta as the leaders of the Peloponnesian League and Sparta's other allies, most notably Thebes, and the Delian League led by Athens with support from Argos. This war consisted of a series of conflicts and minor wars, such as the Second Sacred War. There were several causes for the war including the building of the Athenian long walls, Megara's defection and the envy and concern felt by Sparta at the growth of the Athenian Empire.
The Spartan army was the principle ground force of Sparta. It stood at the center of the Spartan state, consisting of citizens trained in the disciplines and honor of a warrior society. Subjected to military drills since early manhood, the Spartans became one of the most feared and formidable military forces in the Greek world, attaining legendary status in their wars against Persia. At the height of Sparta's power – between the 6th and 4th centuries BC – other Greeks commonly accepted that "one Spartan was worth several men of any other state."
The Theban–Spartan War of 378–362 BC was a series of military conflicts fought between Sparta and Thebes for hegemony over Greece. Sparta had emerged victorious from the Peloponnesian War against Athens, and occupied an hegemonic position over Greece. However, the Spartans' violent interventionism upset their former allies, especially Thebes and Corinth. The resulting Corinthian War ended with a difficult Spartan victory, but the Boeotian League headed by Thebes was also disbanded.
