Vingtième Siècle. Revue d'histoire - Année 1997 - Volume 54 - Numéro 1 - Pages 4-12The expression concentration camp in the 20th century, Annette Wieviorka. One expression, concentration camp, runs through the century since 1901 with the Boers war. But it is too erratic to allow different phenomena to be grasped. Because the meaning of this type of camp can cover a desire to put a population temporarily outside the grasp of the enemy as well as decision of exclusion leading to the establishment of a special world. And there has not been one same concentration system or universe in this century. The historical and comparative study of the camps, this new area opening up to research, can not risk lexical approximation; its intelligence, lucidity and truth are at stake. 9 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
