First Peloponnesian War in the context of "Myronides"

Classical Greece was a period of around 200 years (the 5th and 4th centuries BC) in Ancient Greece, marked by much of the eastern Aegean and northern regions of Greek culture (such as Ionia and Macedonia) gaining increased autonomy from the Persian Empire; the peak flourishing of democratic Athens; the First and Second Peloponnesian Wars; the Spartan and then Theban hegemonies; and the expansion of Macedonia under Philip II. Much of the early defining mathematics, science, artistic thought (architecture, sculpture), theatre, literature, philosophy, and politics of Western civilization derives from this period of Greek history, which had a powerful influence on the later Roman Empire. Part of the broader era of classical antiquity, the classical Greek era ended after Philip II's unification of most of the Greek world against the common enemy of the Persian Empire, which was conquered within 13 years during the wars of Alexander the Great, Philip's son.

In the context of the art, architecture, and culture of ancient Greece, the Classical period corresponds to most of the 5th and 4th centuries BC (the most common dates being the fall of the last Athenian tyrant in 510 BC to the death of Alexander the Great in 323 BC). The Classical period in this sense follows the Greek Dark Ages and Archaic period and is in turn succeeded by the Hellenistic period.

The Battle of Tanagra was a land battle that took place in Boeotia in 457 BC between Athens and Sparta during the First Peloponnesian War. Tension between Athens and Sparta had built up due the rebuilding of Athens' walls and Spartan rejection of Athenian military assistance. The Athenians were led by Myronides and held a strength of 14,000. The Spartans were led by Nicomedes and had a total of 11,500 soldiers. While both the Athenians and Spartans suffered great losses, Sparta ultimately claimed victory in this battle.

The Battle of Oenophyta took place between Athens and the Boeotian city-states in 457 BC during the First Peloponnesian War.

In this period between the Persian Wars and the Peloponnesian War, alliances and leagues sprang up and collapsed, although there was very little prolonged warfare. In 457 BC Athens, the leader of the Delian League, came into conflict with Corinth and their ally Sparta (leader of the Peloponnesian League) over Megara; 62 days prior to the Battle of Oenophyta, the Athenians were defeated at the Battle of Tanagra by Sparta, but Sparta had lost so many men that they could not take advantage of their victory.

Pleistoanax, also spelled Plistoanax, (Ancient Greek: Πλειστοάναξ) was Agiad king of Sparta from 458 to 409 BC. He was the leader of the peace party in Sparta at a time of violent confrontations against Athens for the hegemony over Greece.

The son of Pausanias, Pleistoanax was still a minor in 458 BC, so his uncle Nicomedes acted as regent. His first recorded action was the invasion of Athens in 446 BC as part of the First Peloponnesian War (460–445 BC), but he chose instead to negotiate with Pericles a settlement that became the Thirty Years' Peace. However, Pleistoanax was sued in Sparta for his failure to take Athens and went into exile in Arcadia to avoid punishment. He lived on the sacred ground of Zeus in Mt. Lykaion for the next 18 years.

The 464 BC Spartan earthquake occurred along the Sparta fault in the year 464 BC destroying much of what was Sparta and many other city-states in ancient Greece. Historical sources suggest that the death toll may have been as high as 20,000, although modern scholars suggest that this figure is likely an exaggeration. The earthquake gave Spartan helots an opportunity to revolt against their aristocratic rulers, and the Spartan Pericleidas was sent to the Athenians to seek their aid. Their immediate dismissal upon arrival is said to have been a key event that led up to the First Peloponnesian War.

The Thirty Years' Peace was a treaty signed between the ancient Greek city-states of Athens and Sparta in 446/445 BC. The treaty brought an end to the conflict commonly known as the First Peloponnesian War, which had been raging since c. 460 BC.

The King's Peace (387 BC) was a peace treaty guaranteed by the Persian King Artaxerxes II that ended the Corinthian War in ancient Greece. The treaty is also known as the Peace of Antalcidas, after Antalcidas, the Spartan diplomat who traveled to Susa to negotiate the terms of the treaty with the king of Achaemenid Persia. The treaty was more commonly known in antiquity, however, as the King's Peace, a name that reflects the depth of Persian influence in the treaty, as Persian gold had driven the preceding war. The treaty was a form of Common Peace, similar to the Thirty Years' Peace which ended the First Peloponnesian War.

Pericleidas (Ancient Greek: Περικλείδας; fl. 5th century BCE) was a man of ancient Sparta -- possibly the proxenos of Athens at Sparta -- who played a role during the Peloponnesian War.

After the 464 BC Sparta earthquake, Pericleidas led a diplomatic mission to Athens to appeal for help putting down the revolt of the Helots against the Spartan aristocracy that the earthquake had unleashed. The Athenian general Cimon agreed to this and sent soldiers, but the Spartans rejected them when they arrived, as the Spartans worried that the Athenians' political leanings might make them too sympathetic to the Helots. This rejection was a precipitating event in the First Peloponnesian War.
