Jacques Le Goff (1 January 1924 – 1 April 2014) was a French historian and prolific author specializing in the Middle Ages, particularly the 12th and 13th centuries. Le Goff championed the Annales School movement, which emphasizes long-term trends over the topics of politics, diplomacy, and war that dominated 19th-century historical research. From 1972 to 1977, he was the head of the School for Advanced Studies in the Social Sciences (EHESS) in Paris. He was a leading figure of New History, related to cultural history. Le Goff argued that the Middle Ages formed a civilization of its own, distinct from both Classical Antiquity and the modern world.
