Biography of Thucydides


Thucydides lived so long ago that history as something that we read and write about was still a new concept. Herodotus, the man considered to be the 'Father of History,' was only in his early 20s when Thucydides was born. Therefore, we do not know much about the life of Thucydides. It is known that he lived in ancient Greece from about 460 B.C. to 400 B.C. He came from a wealthy family that earned its money from the gold mines on its land. When Thucydides commanded a fleet for the Athenian Army during the Peloponnesian War in 422 B.C., he could not reach Amphipolis in time to prevent the Spartans from taking control of the city. Thucydides was blamed for the loss and was exiled from Athens. He took that opportunity to spend the next 20 years traveling around Greece and writing about the war.

His Approach to History

Herodotus and Thucydides are compared because they are the first historians of ancient Greece and they had very different approaches to history. Herodotus liked to tell stories. Not every story that he told was true. In fact, Thucydides accused him of inventing fables just to make history more interesting. Thucydides was a scientific historian. He stressed the importance of facts and getting both sides of a story. Thucydides interviewed men who had actually fought in battles instead of just relying on what he heard from others. The quality of his sources was important. He talked to people who were in command and more likely to have accurate information. Another significant difference from Herodotus was that Thucydides did not place an emphasis on the importance of gods in the outcome of events.

The History of the Peloponnesian War

The product of Thucydides' research is The History of the Peloponnesian War. It is eight books that chronicle the war between Sparta and Athens that began in 431 B.C. and ended in 404 B.C. The fact that Thucydides wrote about events that occurred in his lifetime was unusual, but he did it because he believed the war was more important than any war that came before it. While not the first historical text, it set the standard for historical texts to come because it is factual and concise. Eight volumes may not seem concise but it must be remembered that the war, which Sparta eventually won, lasted 27 years. However, Thucydides only got as far as 410 B.C. before the eighth volume abruptly ends in mid-sentence. Most historians believe that Thucydides died before he could finish it.

The Speeches

The History of the Peloponnesian War includes several speeches that Thucydides said were given over the course of the war. He wanted to include these speeches in his work because he believed they offer important insight into the reasons for the war, as well as the ability of the military and political leaders to use persuasive speaking. Thucydides' speeches are not transcripts and he never claimed that they were. He said he wrote the speeches the way he thought they would have been said. This has led some modern historians to suggest that the speeches are better classified as literature. However, other scholars point out that taking notes during speeches and debates was a common practice. If Thucydides was as thorough about gathering those notes as he was with other sources, it is highly possible that his interpretation of the speeches were based on fact.
