The Second Peloponnesian War (431–404 BC), often called the Peloponnesian War, was fought between Athens and Sparta and their respective allies for the hegemony of the ancient Greek world. The war remained undecided until the later intervention of the Persian Empire in support of Sparta. Led by Lysander, the Spartan fleet (built with Persian subsidies) finally defeated Athens, which began a period of Spartan hegemony over Greece.

Historians have traditionally divided the war into three phases. The first phase (431–421 BC) was named the Ten Years War, or the Archidamian War, after the Spartan king Archidamus II, who invaded Attica several times with the full Hoplite army of the Peloponnesian League, the alliance network dominated by Sparta (then known as Lacedaemon). The Long Walls of Athens rendered this strategy ineffective, while the superior navy of the Delian League (Athens' alliance) raided the Peloponnesian coast to trigger rebellions within Sparta. The precarious Peace of Nicias was signed in 421 BC and lasted until 413 BC. Several proxy battles took place during this period, notably the battle of Mantinea in 418 BC, won by Sparta against an ad-hoc alliance of Elis, Mantinea (both former Spartan allies), Argos, and Athens. The main event was the Sicilian Expedition, between 415 and 413 BC, during which Athens lost almost all its navy in the attempt to capture Syracuse, an ally of Sparta.

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.

The Aetolian (or Aitolian) League (Ancient Greek: Κοινὸν τῶν Αἰτωλῶν) was a confederation of tribal communities and cities in ancient Greece centered in Aetolia in Central Greece. It was probably established during the late Classical or the early Hellenistic era. Two annual meetings were held at Thermon and Panaetolika. The league occupied Delphi and steadily gained territory after its victory there against the Gauls in 279 BC. By the end of the 3rd century BC, it controlled the whole of central Greece with the exception of Attica, Euboea, Boeotia and northwestern Acarnania. At its peak, the league's territory included Locris, Phocis, Doris, Malis, Dolopia, Achaia Phthiotis, Ainis, Oetaea, Ambracia and parts of Acarnania. In the latter part of its power, certain Greek city-states out of central Greece joined the Aetolian League such as the Arcadian cities of Mantineia, Tegea, Phigalia and Kydonia on Crete.

During the classical period the Aetolians were not highly regarded by other Greeks, who considered them to be semi-barbaric and reckless. However, during the Hellenistic period, they emerged as a dominant state in central Greece and expanded by annexing several Greek city-states to the League after their victory against the Gauls in 279 BC. Their League had a complex political and administrative structure. The Aetolian League fought against Macedon and the Achaean League in the Social War (220-217 BC), allied with Rome in the First Macedonian War and Second Macedonian War, but then fought against the Romans in an alliance with the Seleucid empire in the Aetolian War before losing its independence to Rome.

Orchomenus or Orchomenos (Greek: Ὀρχομενός) was an ancient city of Arcadia, Greece, called by Thucydides (v. 61) the Arcadian Orchomenus (Ὀρχομενός ὁ Ἀρκαδικός), to distinguish it from the Boeotian town.

Originating as a prehistoric settlement, Orchomenus became one of the powerful cities in West Arcadia along with Tegea and Mantineia. The heyday of the city was between 7th–6th century BC and it became a rich city which minted its own currency.

Nestani (Greek: Νεστάνη, before 1927: Τσιπιανά Tsipiana) is a village and a community in the municipal unit Mantineia, Arcadia, Greece.

Kapsas (Greek: Κάψας, also Κάψια Kapsia) is a community in the municipal unit of Mantineia in Arcadia on the Peloponnese peninsula in southern Greece. It is situated in a valley east of the Mainalo mountains, at 700 m elevation. It is 9 km southeast of Levidi, 11 km west of Nestani and 12 km north of Tripoli. The Greek National Road 74 (Pyrgos - Tripoli) passes through the village.

Alea (Ancient Greek: Ἀλέα) was an epithet of the Greek goddess Athena, prominent in Arcadian mythology, under which she was worshiped at Alea, Mantineia and Tegea. Alea was initially an independent goddess, but was eventually assimilated with Athena. A statue of Athena Alea existed on the road from Sparta to Therapne. Her most important sanctuary was the famous Temple of Athena Alea at Tegea.

Eurypon, otherwise called Eurytion (Ancient Greek: Εὐρυπῶν, Εὐρυτίων), son of Soos and grandson of Procles, was the third king of that house at Sparta, and thenceforward gave it the name of Eurypontidae.

Plutarch talks of his having relaxed the kingly power, and played the demagogue; and Polyaenus relates a war with the Arcadians of Mantineia under his command. He was succeeded by his son Prytanis, the father of Polydectes, in turn father of Eunomus (father of Charilaus) and Lycurgus.

Hymnia (Ancient Greek: Ὑμνία) was an epithet of the Greek goddess Artemis under which she was worshipped throughout Arcadia. She had a temple someplace between Orchomenus and Mantineia. We know from the geographer Pausanias that Orchomenus at least used to hold festivals in her honor.

The priests and priestesses of Hymnia were at first always virgins who were to remain celibate in the priesthood. They were also subject to high standards of propriety, such as being forbidden to enter into the home of a private individual. This lifetime celibacy was fairly unusual for ancient Greek priesthoods.
