RT Review T1 Purify and Destroy: The Political Uses of Massacre and Genocide, Jacques Semelin (New York: Columbia University Press, 2007), xvi + 443 pp., cloth 30.50, pbk. 24.50 JF Holocaust and genocide studies VO 23 IS 3 SP 508 OP 510 A1 Melson, Robert LA English PB Oxford University Press YR 2009 UL https://ixtheo.de/Record/181447949X AB With varying acuity, some important instances of mass murder or genocide have been analyzed by scholars expert in the history and in the culture of the people involved. Mass violence has been so widespread in the modern world that other scholars, not necessarily expert in any one area, have been tempted to juxtapose two or more instances in order to discover underlying patterns and explanations. Scholars have come to understand that comparison does not necessarily imply equivalence; the divergences often prove more instructive., The founder and editor of the Online Encyclopedia of Mass Violence, Jacques Semelin, is professor of political science and research director at the Centre d'Etudes et de Recherches Internationale (CERI) in Paris.
