Egypt revolts against Persia, starting a six-year war.

An Athenian force sent to attack Cyprus is diverted to support this revolt.

Athens, in a failed attempt to aid the Egyptians, loses a fleet and possibly as many as fifty thousand men.

The Middle East: 465–454 BCE

Intrigue and Rebellion in the Persian Empire

Following the military setbacks in the Greek campaign, Xerxes I retreats to his palatial comforts, immersing himself in lavish architectural projects, notably at Persepolis. His reign, however, ends abruptly in 465 BCE when he is assassinated by Artabanus, his chief minister. This conspiracy also results in the murder of Xerxes’ elder son, Darius, leaving the throne to his younger son, who ascends as Artaxerxes I.

Known to the Greeks as Macrocheir ("Longhand"), Artaxerxes I establishes himself at Susa, the administrative heart of his vast empire. His early reign is fraught with palace intrigue and immediate challenges to his authority. Rebellions flare up in distant provinces, particularly in Bactria and Egypt, regions vital to the empire’s economic and strategic stability.

Suppressing these revolts demands significant military engagement, highlighting ongoing tensions between the Persian center and its peripheral territories. Despite these challenges, Artaxerxes manages to reassert Persian dominance, though at considerable cost, setting the stage for a period of uneasy stability marked by cautious governance and persistent regional discontent.

Xerxes, who had retired to his harem after the debacle in the west and devoted his energies to building palaces at Persepolis, is assassinated in 465 by Artabanus, his chief minister; his younger son succeeds him as Artaxerxes I (his elder brother, Darius, having been also murdered).

Artaxerxes, called by the Greeks Macrocheir (Longhand) spends most of his time at Susa.

Court intrigues at the beginning of Artaxerxes’ reign are followed by revolts in the provinces of Bactria and Egypt, which the Persians suppress after considerable fighting.

Near East (466–454 BCE): Egyptian Revolt, Judahite Resettlement, and Religious Reformation

Between 466 and 453 BCE, the Near East experiences notable political upheaval, strategic setbacks, and significant cultural developments. Central to the period is a major revolt by Egypt against Persian rule, sparking a prolonged six-year conflict. Initially hopeful, Egyptian resistance soon escalates into a broader international struggle when Athens diverts military resources originally intended for an assault on Cyprus to support the Egyptian insurgents. The Athenian decision results in disastrous losses, including a substantial portion of their naval fleet and possibly as many as fifty thousand soldiers, severely weakening their strategic capabilities in the eastern Mediterranean.

Meanwhile, in Palestine, returning Judahites from the Babylonian exile continue their intensive efforts at resettlement and reconstruction. Bethlehem is among the key towns repopulated during this period, symbolizing a broader renewal of Judahite communal and religious identity. Amidst these significant demographic shifts, the Persian court sends the influential scribe Ezra to Jerusalem in 458 BCE (though alternative chronologies place his arrival in either 428 or 397 BCE). Ezra's mission, as recorded in biblical tradition, is to reinforce adherence to religious law and to address controversial intermarriages with non-Judahites, an effort aimed at solidifying community cohesion and religious purity.

These developments collectively highlight a complex regional dynamic characterized by resistance to Persian authority, international entanglements, and a determined cultural and religious revival within Judahite society. The Near East thus continues to be shaped profoundly by the interplay of political power struggles and the assertion of local identities across Egypt, Palestine, and the broader eastern Mediterranean region.

Bethlehem is among the towns repopulated by the Judahites returning from Babylonia to Palestine.

The scribe Ezra, according to the Bible, is sent to Jerusalem from the Persian court in 458 BCE.

The purposes of his mission are (according to one view of the Book of Ezra) apparently to introduce stricter observance of the Law and to dissolve marriages with foreigners.

Other scholars date Ezra’s arrival at 428 BCE or 397 BCE.

Ezra, with the Book of Nehemiah, were originally one work in the Hebrew canon, and scholars disagree on whether the two books were written by the same hand.

Athens and the island of Thasos, a powerful naval state, come into conflict over control of gold deposits on the Thracian mainland, which Thasos has traditionally mined.

Thasos rebels against Athenian control, seeking to renounce its membership in the Delian League.

The rebellion is eventually crushed, after a long and difficult siege, but not before Sparta has secretly promised to invade Attica in support of the Thasians.

The Spartans are prevented from making good on this promise only by an earthquake in Laconia, which triggers a helot rebellion.

The uprising of the helots against their Spartan overlords in the Peloponnese, coincident with the earthquake of 464 BCE, is soundly attested in contemporary or near-contemporary writings, although Greek historians do not agree on the interpretation of this event.

This appears in any case to lead to strained relations between Sparta and Athens, one of the factors that leads to the Peloponnesian War.

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, the First Peloponnesian War consists of a series of conflicts and minor wars, such as the Second Sacred War.

There are several causes for the war, including the building of the Athenian Long Walls, Megara's defection and the envy felt by Sparta at the growth of the Athenian Empire.

Greek mathematicians use the theorem of Pythagoras to make the discovery that in a square with sides of length one, the length of its diagonal d is a number whose square is two (d(2) = 2).

The Greeks initially try to find a rational number whose square is 2, but, about 460 BCE, they finally prove that d = the square root of 2 is not rational.

Mathematicians have, therefore, to expand their concept of a number to include these irrational numbers, or surds.

Theorists of the time are unable to determine as rational or irrational another mysterious number which arose naturally, the Greek letter pi—the ratio of the circumference of a circle to its diameter.

The magnificent Temple of Zeus at Olympia is the very model of the fully developed classical Greek temple of the Doric order.

Built between 472 and 456 BCE, the temple stands in the most famous sanctuary of Greece, which had been dedicated to local and Pan-Hellenic deities and had probably been established towards the end of the Mycenaean period.

The Altis, the enclosure with its sacred grove, open-air altars and the tumulus of Pelops, was first formed during the tenth and ninth centuries BCE, when the cult of Zeus was joined to the already established cult here of Hera.

The temple was constructed by the architect Libon, with carved metopes and triglyph friezes, topped by pediments filled with sculptures in the Severe Style, now attributed to the "Olympia Master" and his studio.

The main structure of the building was of a local limestone that was unattractive and of poor quality, and so it was coated with a thin layer of stucco to give it an appearance of marble.

All the sculptural decoration on the temple was made of Parian marble, and the roof tiles were of the same Pentelic marble used to build the Parthenon at Athens.

The Artemision Bronze (often called the God from the Sea) is an ancient Greek sculpture that was recovered from the sea off Cape Artemision, in northern Euboea.

It represents either Zeus or Poseidon, slightly over lifesize, brandishing a missing thunderbolt (if Zeus) or trident (if Poseidon) with his raised right hand and sighting over his extended left hand.

The empty eye-sockets were originally inset, probably with bone, as well as the eyebrows (with silver), the lips, and the nipples (with copper).

The god is caught at the moment of pause in the full potentiality of his coming movement, described by Carol Mattusch: "the figure has the potential for violence, is concentrating, poised to throw, but the action is just beginning, and we are left to contemplate the coming demonstration of strength.

It is an original work of great strength in the Severe style that preceded the fifth-century classical style, dated to around 460 BCE.

A comparison can be made with the Charioteer of Delphi, a roughly contemporaneous bronze.
