Book VIII

Thucydides announces that he is writing the history of the Peloponnesian War because he believes it will be great and worthy of relation, based on the preparations of both combatants and the vast scope of the conflict.

Thucydides argues that ancient Greece was characterized by constant migrations, lack of commerce, absence of wall-building, and scattered populations—all indicators of a weak and disorganized society.

Athens uniquely maintained a stable population due to its poor soil, which discouraged invasion and faction, allowing it to become a refuge and eventually a populous center.

Thucydides traces how the name 'Hellas' and 'Hellenes' gradually spread from the descendants of Hellen in Phthiotis, providing evidence of collective identity only slowly developing.

Thucydides credits Minos with establishing the first known navy, which enabled him to control the sea, colonize islands, and suppress piracy—a crucial development for Greek unity.

Thucydides demonstrates that piracy and brigandage were widespread and even honored in ancient times, practiced by both Greeks and barbarians, with no social disgrace attached.

Thucydides notes that some regions of Greece and barbarian lands still maintain customs of the ancient world, particularly regarding arms-bearing and simple dress, indicating the universality of primitive conditions.

As commerce and capital increased, towns gradually moved from inland defensive positions to fortified coastal settlements, enabling trade and defense against both pirates and rival states.

The purification of Delos revealed Carian burials, providing historical evidence that these peoples colonized the Greek islands before Minos expelled them.

After Minos established his navy and colonized the islands, communication became safer, populations stabilized, wealth accumulated, and the Greeks eventually launched the Trojan expedition.

Thucydides argues that Agamemnon's personal strength and inherited power, rather than oaths alone, enabled him to raise the army against Troy, with his superior navy being the key factor.

Thucydides traces how Pelops brought wealth from Asia, which expanded through his descendants, allowing Agamemnon to accumulate power through inheritance and naval superiority.

Thucydides argues that the famous Trojan expedition, while the greatest of its time, was actually quite small compared to modern forces, based on careful analysis of Homer.

Using Lacedaemon as an example, Thucydides argues that a city's physical appearance is unreliable evidence of its true power, as scattered villages can harbor great strength.

Thucydides calculates the actual size of the Trojan expedition from Homer's account of twelve hundred ships with varying crew sizes, concluding it was surprisingly small.

After Troy, Greece remained unsettled with migrations and factional conflicts, delaying the development of stable states and colonial expansion.

As Greek power grew and wealth accumulated, tyrannies emerged as common forms of government, replacing hereditary monarchies and leading to expansion of naval power.

Thucydides credits the Corinthians with pioneering modern galley construction, which emerged from their position as a commercial hub benefiting from land and sea trade.

The earliest naval battle in history occurred between Corinthians and Corcyraeans about 260 years before, marking the transition to naval warfare.

Corinth's prosperity as a commercial hub for land trade enabled it to build a navy, suppress piracy, and achieve great naval power.

The Ionians, Samians, and others developed naval power in later periods, but even these remained limited until the Persian Wars prompted more extensive naval development.

It was only Themistocles' persuasion of the Athenians, prompted by the threat of Persian invasion, that led to building the first complete fleet used at Salamis.

Although ancient navies were insignificant by later standards, they were the chief means of acquiring power through controlling islands and trade.

Large-scale land wars were absent in ancient Greece; conflicts were local and limited, with no major coalitions forming for distant conquest.

The advancing Ionian power collided with the Persian empire under Cyrus, which stopped further Greek expansion eastward by conquering coastal cities.

Tyrants focused on personal safety and family advantage rather than state power, preventing great collective achievements except in Sicily.

Unlike other Greek states, Lacedaemon maintained stable laws, avoided tyranny for four hundred years, and positioned itself to arrange affairs of other states.

The Persian invasions forced the Greeks to unite, with Sparta initially commanding, but Athens became a naval power and later led an Athenian alliance against the barbarian.

After repelling the Persians, the Greek alliance split into Athenian naval and Lacedaemonian military factions, leading to conflict between the two powers.

Lacedaemon secured subservience through oligarchies without tribute, while Athens gradually stripped allies of ships and imposed monetary contributions.

Thucydides notes that most people accept traditions uncritically, providing examples of false beliefs about Athenian history that persist despite being demonstrably wrong.

Thucydides corrects the misconception that Hipparchus was tyrant when killed; actually Hippias held power, and the assassination was motivated by personal suspicion rather than political principle.

Thucydides cites additional errors in belief, such as Lacedaemonian kings having two votes and the existence of a Pitane company, showing how careless people are with truth.

Thucydides asserts that his conclusions rest on the clearest evidence and will not be disturbed by poetic exaggeration or mythological elaboration.

Thucydides concludes that the Peloponnesian War, though smaller than commonly remembered, was greater and more consequential than any previous war.

Thucydides explains that he preserves the general sense of speeches while making speakers say what the occasions demanded, prioritizing the substance over exact wording.

Thucydides reports that he tested accounts rigorously through multiple sources and firsthand observation, acknowledging the difficulty of reconciling contradictory eyewitness reports.

Thucydides states his history is written as a permanent possession offering exact knowledge for interpreting the future, not to win momentary applause.

The Median War was decided quickly, while the Peloponnesian War was prolonged and caused unprecedented destruction, earthquakes, eclipses, famine, and plague.

Thucydides identifies the true cause as Athenian power growth and Lacedaemonian alarm, though formal grievances are presented separately.
