Thucydides was an Athenian historian and General who wrote about the Peloponnesian War between Athens and Sparta in the 5th century BC. Thucydides, the famous historian, was born around 460 BC in Halimous, Athens, and he had Thracian blood in him since his father was Olorus of the Thracian royal lineage. Thucydides' family was wealthy due to the gold mines in Thrace, which allowed him to indulge in his academic passion. He escaped the fatal Athenian plague that killed many people, including Pericles, and later became a general.

In 424 BC, he was dispatched as a general to Thasos. However, he was exiled due to his inability to protect Amphipolis from the Spartans. Exile helped him collect a lot of information from both sides of the conflict, and thus, he had a somewhat different vision of the events. Thucydides is the father of "scientific history" because he removed divine intervention from historical analysis methods and meticulously collected evidence. His work remains the most influential for historians and political theorists interested in studying human nature in crises.

Still, information concerning Thucydides's life is relatively scarce, though his work is significant. Only after the war do some sources tell us that he may have returned to Athens, but this information is scarce and often confusing. His story was brought to a sudden halt in 411 BC, which has given rise to much discussion over his death. However, his ideas are still remembered through the works he left behind in historical methodology and political philosophy.
