Thucydides: The First Scientific Historian

Discover Thucydides, the ancient Greek general and historian whose account of the Peloponnesian War established the foundations of modern history.
What is it?
Thucydides (c. 460 – c. 400 BC) was an Athenian historian and general. He is renowned for his work, the History of the Peloponnesian War, which provides a detailed contemporary account of the 27-year conflict between Athens and Sparta. Unlike his predecessor Herodotus, Thucydides sought to explain events through cause and effect, focusing on human actions and motivations without reference to divine intervention. This rigorous approach, based on evidence-gathering and impartiality, has earned him the title of the "father of scientific history". His analysis of political behavior, viewing it as driven by fear and self-interest, also makes him a foundational figure in the school of political realism.
Why is it trending?
Thucydides' work remains profoundly relevant and is still studied at universities and military colleges worldwide. His insights into war, power dynamics, and human nature are seen as timeless. The term "Thucydides Trap," which describes the tendency toward war when a rising power threatens to displace an existing great power, is frequently cited in modern international relations, especially concerning relationships like that between the U.S. and China. His examination of conflict, diplomacy, and the moral decline of societies during protracted wars provides enduring lessons for contemporary strategists and policymakers.
