The French Annales School radically changed the focus of historical research in France during the 20th century by stressing long-term social history, rather than political or diplomatic themes. The school emphasized the use of quantification and the paying of special attention to geography. An eminent member of this school, Georges Duby, described his approach to history as one that relegated the sensational to the sidelines and was reluctant to give a simple accounting of events, but strived on the contrary to pose and solve problems and, neglecting surface disturbances, to observe the long and medium-term evolution of economy, society, and civilisation.
