Thucydides (c. 460 BC – c. 395 BC) (Greek Θουκυδίδης, Thoukydídēs) was a Greek historian and author of the History of the Peloponnesian War, which recounts the 5th century BC war between Sparta and Athens to the year 411 BC. Thucydides has been dubbed the father of "scientific history" because of his strict standards of evidence-gathering and analysis in terms of cause and effect without reference to intervention by the gods, as outlined in his introduction to his work.
He has also been called the father of the school of political realism, which views the relations between nations as based on might rather than right. His classical text is still studied at advanced military colleges worldwide, and the Melian dialogue remains a seminal work of international relations theory.
More generally, Thucydides showed an interest in developing an understanding of human nature to explain behaviour in such crises as plague, massacres, as in that of the Melians, and civil war.
In spite of his stature as a historian, modern historians know relatively little about Thucydides' life. The most reliable information comes from his own History of the Peloponnesian War, which expounds his nationality, paternity and native locality. Thucydides informs us 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.
Evidence from the Classical Period
Thucydides identifies himself as an Athenian, telling us that his father's name was Olorus and that he was from the Athenian deme of Halimous. He survived the Plague of Athens that killed Pericles and many other Athenians. He also records that he owned gold mines at Scapte Hyle (literally: "Dug Woodland"), a coastal area in Thrace, opposite the island of Thasos.
Because of his influence in the Thracian region, Thucydides wrote, he was sent as a strategos (general) to Thasos in 424 BC During the winter of 424-423 BC, the Spartan general Brasidas attacked Amphipolis, a half-day's sail west from Thasos on the Thracian coast. Eucles, the Athenian commander at Amphipolis, sent to Thucydides for help. Brasidas, aware of Thucydides's presence on Thasos and his influence with the people of Amphipolis, and afraid of help arriving by sea, acted quickly to offer moderate terms to the Amphipolitans for their surrender, which they accepted. Thus, when Thucydides arrived, Amphipolis was already under Spartan control. (See Battle of Amphipolis.)
Amphipolis was of considerable strategic importance, and news of its fall caused great consternation in Athens. It was blamed on Thucydides, although he claimed that it was not his fault and that he had simply been unable to reach it in time. Because of his failure to save Amphipolis, he was sent into exile:
" It was also my fate to be an exile from my country for twenty years after my command at Amphipolis; and being present with both parties, and more especially with the Peloponnesians by reason of my exile, I had leisure to observe affairs somewhat particularly. "
Using his status as an exile from Athens to travel freely among the Peloponnesian allies, he was able to view the war from the perspective of both sides. During this time, he conducted important research for his history, having claimed that he pursued the project as he thought it would be one of the greatest wars waged among the Greeks in terms of scale.
This is all that Thucydides wrote about his own life, but a few other facts are available from reliable contemporary sources. Herodotus wrote that Thucydides' father's name, Όloros, was connected with Thrace and Thracian royalty. Thucydides was probably connected through family to the Athenian statesman and general Miltiades, and his son Cimon, leaders of the old aristocracy supplanted by the Radical Democrats. Cimon's maternal grandfather's name was also Olorus, making the connection exceedingly likely. Another Thucydides lived before the historian and was also linked with Thrace, making a family connection between them very likely as well. Finally, Herodotus confirms the connection of Thucydides' family with the mines at Scapté Hýlē.
Combining all the fragmentary evidence available, it seems that his family had owned a large estate in Thrace, one that even contained gold mines, and which allowed the family considerable and lasting affluence. The security and continued prosperity of the wealthy estate must have necessitated formal ties with local kings or chieftains, which explains the adoption of the distinctly Thracian royal name "Όloros" into the family. Once exiled, Thucydides took permanent residence in the estate and, given his ample income from the gold mines, he was able to dedicate himself to full-time history writing and research, including many fact-finding trips. In essence he was by then a retired, well-connected gentleman of considerable resources who, by then retired from the political and military spheres, decided to fund his own scientific project.
The remaining evidence for Thucydides' life comes from rather less reliable later ancient sources. According to Pausanias, someone named Oenobius was able to get a law passed allowing Thucydides to return to Athens, presumably sometime shortly after the city's surrender and the end of the war in 404 BC Pausanias goes on to say that Thucydides was murdered on his way back to Athens. Many doubt this account, seeing evidence to suggest he lived as late as 397 BC. Plutarch claims that his remains were returned to Athens and placed in Cimon's family vault.
The abrupt end to Thucydides' narrative, which breaks off in the middle of the year 411 BC, has traditionally been interpreted as indicating that he died while writing the book, although other explanations have been put forward.
Inferences about Thucydides' character can only be drawn (with due caution) from his book. His sardonic sense of humor is evident throughout, as when, during his description of the Athenian plague, he remarks that old Athenians seemed to remember a rhyme which said that with the Dorian War would come a "great death". Some claimed that the rhyme was actually about a "great dearth" (limos), and was only remembered as "death" (loimos) due to the current plague. Thucydides then remarks that, should another Dorian War come, this time attended with a great dearth, the rhyme will be remembered as "dearth," and any mention of "death" forgotten.
Thucydides admired Pericles, approving of his power over the people and shows a marked distaste for the demagogues who followed him. He did not approve of the democratic mob nor the radical democracy that Pericles ushered in but considered democracy acceptable when guided by a good leader. Thucydides's presentation of events is generally evenhanded, for example, he does not minimize the negative effect of his own failure at Amphipolis. Occasionally, however, strong passions break through, as in his scathing appraisals of the demagogues Cleon; Thucydides 4.27; Thucydides 5.16.1 and Hyperbolus. Cleon has sometimes been connected with Thucydides' exile.
That Thucydides was clearly moved by the suffering inherent in war and concerned about the excesses to which human nature is prone in such circumstances is evident in his analysis of the atrocities committed during civil conflict on Corcyra, which includes the phrase "War is a violent teacher".
The History of the Peloponnesian War
After his death, Thucydides's history was subdivided into eight books: its modern title is the History of the Peloponnesian War. His great contribution to history and historiography is contained in this one dense history of the 27-year war between Athens, Sparta, and their respective allies. The history breaks off near the end of the 21st year; the last sketchy book suggests that his death was unexpected and may possibly have been sudden or violent. Thucydides believed that the Peloponnesian War represented an event of unmatched magnitude. His intention was to write an account of the events of the late fifth century which would serve as "a possession for all time."
Thucydides is generally regarded as one of the first true historians. Like his predecessor Herodotus, known as "the father of history", Thucydides places a high value on eyewitness testimony and writes about events in which he himself probably took part. He also assiduously consulted written documents and interviewed participants about the events that he recorded. Unlike Herodotus, whose stories often teach that a foolish arrogance hubris invites the wrath of the gods, Thucydides does not acknowledge divine intervention in human affairs.
A noteworthy difference between Thucydides' method of writing history and that of modern historians is Thucydides' inclusion of lengthy formal speeches that, as he himself states, were literary reconstructions rather than actual quotations of what was said - or, perhaps, what he believed ought to have been said. Arguably, had he not done this, the gist of what was said would not otherwise be known at all - whereas today there is a plethora of documentation - written records, archives, and recording technology for historians to consult. Therefore Thucydides method served to rescue his mostly oral sources from oblivion. We do not know how these historical figures actually spoke. Thucydides' recreation uses a heroic stylistic register. A celebrated example is Pericles' funeral oration, which heaps honor on the dead and includes a defense of democracy:
" The whole earth is the sepulcher of famous men; they are honored not only by columns and inscriptions in their own land, but in foreign nations on memorials graven not on stone but in the hearts and minds of men. "
Stylistically, the placement of this passage also serves to heighten the contrast with the description of the plague in Athens immediately following it, which graphically emphasizes the horror of human mortality thereby conveying a powerful sense of verisimilitude:
" Though many lay unburied, birds and beasts would not touch them, or died after tasting them [...]. The bodies of dying men lay one upon another, and half-dead creatures reeled about the streets and gathered round all the fountains in their longing for water. The sacred places also in which they had quartered themselves were full of corpses of persons who had died there, just as they were; for, as the disaster passed all bounds, men, not knowing what was to become of them, became equally contemptuous of the gods' property and the gods' dues. All the burial rites before in use were entirely upset, and they buried the bodies as best they could. Many from want of the proper appliances, through so many of their friends having died already, had recourse to the most shameless sepultures: sometimes getting the start of those who had raised a pile, they threw their own dead body upon the stranger's pyre and ignited it; sometimes they tossed the corpse which they were carrying on the top of another that was burning, and so went off. "
Thucydides omits discussion of the arts, literature, or the social milieu in which the events in his book take place and in which he himself grew up. He saw himself as recording an event, not a period, and went to considerable lengths to exclude what he deemed frivolous and / or extraneous. Some consider this framing in itself as constituting a form of value judgment. Historian and classical scholar Peter Green remarks that:
The cleverest intellectual move Thucydides made was the severe limiting of what he deemed permissible as elements of historiography, on the grounds that everything else outside this canon was not only irrelevant but unserious. Out went personal anecdotes, most foreign ethnography, and domestic or private motivation: out, above all, went anything to do with women. Religion was women's business, and mostly nonsense anyway, so that could be discarded too. The essence of history was war and politics, as conducted by men in authority. His exclusive privileging of the male political association, in its most public form, became accepted, and historians (being political males themselves) were not inclined to argue. His revisionism not only won out at the time, but established the basic principles of historiography for over two millennia
Scholars traditionally view Thucydides as recognizing and teaching the lesson that democracies need leadership, but that leadership can be dangerous to democracy. Leo Strauss (in The City and Man) locates the problem in the nature of Athenian democracy itself, about which, he argued, Thucydides had a deeply ambivalent view: on one hand, Thucydides' own "wisdom was made possible" by the Periclean democracy, which had the effect of liberating individual daring, enterprise, and questioning spirit, but this same liberation, by permitting the growth of limitless political ambition, led to imperialism and, eventually, civic strife.
For Canadian historian Charles Norris Cochrane (1889–1945), Thucydides' fastidious devotion to observable phenomena, focus on cause and effect, and strict exclusion of other factors anticipates twentieth century scientific positivism. Cochrane, the son of a physician, speculated that Thucydides' generally (and especially in describing the plague in Athens) was influenced by the methods and thinking of early medical writers such as Hippocrates of Kos.
After World War II Classical scholar Jacqueline de Romilly pointed out that the problem of Athenian imperialism was one of Thucydides' central preoccupations and situated his history in the context of Greek thinking about international politics. Since the appearance of her study, other scholars subsequently further examined Thucydides treatment of realpolitik.
More recently, scholars have questioned the perception of Thucydides as simply "the father of realpolitik". Instead foreground the literary qualities of the History, which they see as belonging to narrative tradition of Homer and Hesiod and as concerned with the concepts of justice and suffering found in Plato and Aristotle and problematized in Aeschylus and Sophocles  Richard Ned Lebow believes that the modern habit of erecting a firewall of separation between the social sciences and the ethical preoccupations of the humanities is a mistake, since no such separation was ever obtained in the ancient world. He and other recent scholars affirm that Thucydides was indeed concerned with ethical issues such as prudence and the need for peace: and that even though he did not explicitly engage in moralizing within his text, his work conveys a profound horror of war and violence. Lebow terms Thucydides: "the last of the tragedians:
Viewed as a tragedy, his portrayal of the Peloponnesian War leads us to a very different set of questions, understandings of politics and of knowledge itself. . . Greek tragedy was rooted in the empirical observation that there is no relationship between justice and suffering. Tragedy confronts us with our frailties and limits and the disastrous consequences of trying to exceed them. It advances a counter-intuitive thesis: that efforts to limit suffering through the accumulation of knowledge or power might invite more suffering. . . Thucydides drew heavily on epic poetry and tragedy to construct his history, which not surprisingly is also constructed as a narrative.
In this view, the blind and immoderate behavior of the Athenians (and indeed of all the other actors), though perhaps intrinsic to human nature, ultimately leads to their downfall. Thus his History could serve as a warning to future leaders to be more prudent, by putting them on notice that someone would be scrutinizing their actions with a historian's objectivity rather than a chronicler's flattery.
Thucydides versus Herodotus
Thucydides and his immediate predecessor Herodotus both exerted a significant influence on Western historiography. Thucydides does not mention his counterpart by name, but his famous introductory statement is thought to refer to him.
" To hear this history rehearsed, for that there be inserted in it no fables, shall be perhaps not delightful. But he that desires to look into the truth of things done, and which (according to the condition of humanity) may be done again, or at least their like, shall find enough herein to make him think it profitable. And it is compiled rather for an everlasting possession than to be rehearsed for a prize. "
Herodotus records in his Histories not only the events of the Persian Wars but also geographical and ethnographical information, as well as the fables related to him during his extensive travels. Typically, he passes no definitive judgment on what he has heard, In the case of conflicting or unlikely accounts, he presents both sides, says what he believes and then invites readers to decide for themselves. The work of Herodotus is reported  to have been recited at festivals, where prizes were awarded, as for example, during the games at Olympia.
Herodotus views history as a source of moral lessons, with conflicts and wars as misfortunes flowing from initial acts of injustice perpetuated through cycles of revenge. In contrast, Thucydides claims to confine himself to factual reports of contemporary political and military events, based on unambiguous, first-hand, eye-witness accounts, although – unlike Herodotus – he does not reveal his sources. Thucydides views life exclusively as political life, and history in terms of political history. Conventional moral considerations plays no role in his analysis of political events while geographic and ethnographic aspects are omitted or, at best, of secondary importance. Subsequent Greek historians - such as Ctesias, Diodorus, Strabo, Polybius and Plutarch - held up Thucydides' writings as a model of truthful history. Lucian refers to Thucydides as having given Greek historians their law, requiring them to say what had been done (ὡς ἐπράχθη). Greek historians of the fourth century BC accepted that history was political and that contemporary history was the proper domain of a historian.. Cicero calls Herodotus the "father of history;" yet the Greek writer Plutarch, in his Moralia (Ethics) denigrated Herodotus, as the "father of lies". Unlike Thucydides, however, these historians all continued to view history as a source of moral lessons.
Due to the loss of the ability to read Greek, Thucydides and Herodotus were largely forgotten during the Middle Ages in Western Europe, although their influence continued in the Byzantine world. In Europe, Herodotus become known and highly respected only in the late-sixteenth and early- seventeenth century as an ethnographer, in part due to the discovery of America, where customs and animals were encountered even more surprising than what he had related. During the Reformation, moreover, information about Middle Eastern countries in the Histories provided a basis for establishing Biblical chronology as advocated by Isaac Newton.
The first European translation of Thucydides (into Latin) was made by the humanist Lorenzo Valla between 1448 and 1452, and the first Greek edition was published by Aldo Manunzio in 1502. During the Renaissance, however, Thucydides attracted less interest among Western European historians as a political philosopher than his successor, Polybius, although Poggio Bracciolini claimed to have been influenced by him. There is not much trace of Thucydides' influence in Niccolò Machiavelli's The Prince (1513), which held that the chief aim of a new prince must be to "maintain his state" [i.e., his power] and that in so doing he is often compelled to act against faith, humanity and religion. Later historians, such as J. B. Bury, however, have noted parallels between them:
If, instead of a history, Thucydides had written an analytical treatise on politics, with particular reference to the Athenian empire, it is probable that . . . he could have forestalled Machiavelli. . . .[since] the whole innuendo of the Thucydidean treatment of history agrees with the fundamental postulate of Machiavelli, the supremacy of reason of state. To maintain a state said the Florentine thinker, "a statesman is often compelled to act against faith, humanity, and religion." . . . But . . . the true Machiavelli, not the Machiavelli of fable. . . entertained an ideal: Italy for the Italians, Italy freed from the stranger: and in the service of this ideal he desired to see his speculative science of politics applied. Thucydides has no political aim in view: he was purely a historian. But it was part of the method of both alike to eliminate conventional sentiment and morality.
In the seventeenth century, the English political philosopher Thomas Hobbes, whose Leviathan advocated absolute monarchy, admired Thucydides and in 1628 was the first to translate his writings into English directly from Greek. Thucydides, Hobbes, and Machiavelli are together considered the founding fathers of political realism, according to which state policy must primarily or solely focus on the need to maintain military and economic power rather than on ideals or ethics. Nineteenth-century positivist historians stressed what they saw as Thucydides' seriousness, his scientific objectivity, and his advanced handling of evidence. A virtual cult following developed among such German philosophers as Friedrich Schelling, Friedrich Schlegel, and Friedrich Nietzsche, who claimed that, "[in Thucydides], the portrayer of man, that culture of the most impartial knowledge of the world finds its last glorious flower." For Eduard Meyer, Macaulay, and Leopold von Ranke, who initiated modern source-based history writing  Thucydides was again the model historian..
Generals and statesmen loved him: the world he drew was theirs, an exclusive power-brokers' club. It is no accident that even today Thucydides turns up as a guiding spirit in military academies, neocon think tanks, and the writings of men like Henry Kissinger; whereas Herodotus has been the choice of imaginative novelists (Michael Ondaatje's The English Patient, and the film based on it, boosted the sale of the Histories to a wholly unforeseen degree) and - as food for a starved soul - of an equally imaginative foreign correspondent from Iron Curtain Poland, Ryszard Kapuscinski .
These historians also admired Herodotus, however, as social and ethnographic history increasingly came to be recognized as complementary to political history. In the twentieth century, this trend gave rise to the works of Johan Huizinga, Marc Bloch, and Braudel, who pioneered a the study of long-term cultural and economic developments, and the patterns of everyday life. The Annales School, which exemplifies this direction, has been viewed as extending the tradition of Herodotus.
At the same time, Thucydides' influence was increasingly important in the area of international relations during the Cold War, through the work of Hans Morgenthau, Leo Strauss, and Edward Carr.
The tension between the Thucydidean and Herodotean traditions extends beyond historical research. According to Irving Kristol, self-described founder of American Neoconservatism, Thucydides wrote "the favorite neoconservative text on foreign affairs," and Thucydides is a required text at the Naval War College, an American institution located in Rhode Island. On the other hand, Daniel Mendelsohn, in a review of a recent edition of Herodotus, suggests that at least in his graduate school days during the Cold War, professing admiration of Thucydides served as a form of self-presentation:
To be an admirer of Thucydides' History, with its deep cynicism about political, rhetorical, and ideological hypocrisy, with its all too recognizable protagonists - a liberal yet imperialistic democracy and an authoritarian oligarchy, engaged in a war of attrition fought by proxy at the remote fringes of empire - was to advertise yourself as a hardheaded connoisseur of global Realpolitik.
Another author, Thomas Geoghegan, whose specialty is labor rights, comes down on the side of Herodotus when it comes to drawing lessons relevant to Americans, whom, he notes, tend to be rather isolationist in their habits (if not in their political theorizing): "We should also spend more funds to get our young people out of the library where they're reading Thucydides and get them to start living like Herodotus - going out and seeing the world."
Thucydides in popular culture
In 1991, the BBC broadcast a new version of John Barton's 'The War that Never Ends', which had first been performed on stage in the 1960s. This adapts Thucydides' text, together with short sections from Plato's dialogues. More information about it can be found on the Internet Movie Database.
* "But, the bravest are surely those who have the clearest vision of what is before them, glory and danger alike, and yet notwithstanding, go out to meet it."
* "Right, as the world goes, is only in question between equals in power, while the strong do what they can and the weak suffer what they must."
* "It is a general rule of human nature that people despise those who treat them well, and look up to those who make no concessions."
* "War takes away the easy supply of daily wants, and so proves a rough master, that brings most men's characters to a level with their fortunes."
* "The cause of all these evils was the lust for power arising from greed and ambition; and from these passions proceeded the violence of parties once engaged in contention."
* "So that, though overcome by three of the greatest things, honour, fear, and profit, we have both accepted the dominion delivered us and refuse again to surrender it, we have therein done nothing to be wondered at nor beside the manner of men. "
Quotations about Thucydides
And after [the time of Herodotus], Thucydides, in my opinion, easily vanquished all in the artfulness of his style: he so concentrates his copious material that he almost matches the number of his words with the number of his thoughts. In his words, further, he is so apposite and compressed that you do not know whether his matter is being illuminated by his diction or his words by his thoughts. (Cicero,De Oratore 2.56 (55 B.C.))
In the preface to his 1628 translation of Thucydides, entitled, Eight Bookes of the Peloponesian Warres, political philosopher Thomas Hobbes calls Thucydides
"the most politic historiographer that ever writ."
A hundred years later, philosopher David Hume, wrote that:
[T]he first page of Thucydides is, in my opinion, the commencement of real history. All preceding narrations are so intermixed with fable, that philosophers ought to abandon them to the embellishments of poets and orators. ("Of the Populousness of Ancient Nations", 1742)
W. H. Auden's poem, "September 1, 1939", written at the start of World War II, contains these lines:
Exiled Thucydides knew
All that a speech can say
And what dictators do,
The elderly rubbish they talk
To an apathetic grave;
Analysed all in his book,
The enlightenment driven away,
The habit-forming pain,
Mismanagement and grief:
We must suffer them all again.
