Source-derived summary

Thucydides ( thew-SID-ih-deez; Ancient Greek: Θουκυδίδης, romanised: Thoukudídēs [tʰuːkydǐdɛːs]; c. 460 – c. 400 BC) was an Athenian historian and general. His History of the Peloponnesian War recounts the 5th century BC war between Sparta and Athens until the year 411 BC. Thucydides has been dubbed the father of "scientific history" by those who accept his claims to have applied strict standards of impartiality and evidence-gathering and analysis of cause and effect, without reference to intervention by the gods, as outlined in his introduction to his work.

Thucydides has been called the father of the school of political realism, which views the political behaviour of individuals and the subsequent outcomes of relations between states as ultimately mediated by, and constructed upon, fear and self-interest. His text is still studied at universities and military colleges worldwide. The Melian dialogue is regarded as a seminal text of international relations theory, while his version of Pericles's Funeral Oration is widely studied by political theorists, historians, and students of the classics. More generally, Thucydides developed an understanding of human nature to explain behaviour in such crises as plagues, massacres, and wars.

Life

In spite of his stature as a historian, modern historians know relatively little about Thucydides's life. The most reliable information comes from his own History of the Peloponnesian War, in which he mentions his nationality, paternity, and birthplace. Thucydides says that he fought in the war, contracted the plague, and was exiled by the democracy. He may have also been involved in quelling the Samian Revolt.

Editorial summary

This brief starts where responsible research should: with the source description of “Thucydides” as 5th-century BC Athenian historian and general. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewStrongest as a route into the people, institutions and dated events that shaped the subject’s public record. The current 254-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date -0460. The account is most persuasive where Thucydides, 5th-century and Athenian can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the people & ideas register because the source frames it as 5th-century BC Athenian historian and general. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Jun 23, 2026. The linked authority identifier is Q41683. VIAF identifies the subject as 95161463. The Library of Congress control number is n79021175. 2 of 20 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.

Critical limits

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
