The articles collected in this volume represent the independent and considered thinking of internationally known scholars from a variety of disciplines concerning the relationship between religion and violence, with special reference to the theories of "just war" and "jihad," technical terms that arise in connection with the theology of early medieval Christianity and early Islam, respectively. The contributors include Hector Avalos, Charles K. Bellinger, Bahar Davary, Carol Delaney, J. Harold Ellens, Reuven Firestone, R. Joseph Hoffmann, Judith Lichtenberg, Pauletta Otis, Gabriel Palmer-Fernandez, Laura Purdy, Joyce E. Salisbury, Regina M. Schwartz, and Robert B. Tapp. In the present global and political climate, the significant conversation about why religions provoke conflict and whether any religion is truly "harmless" cannot be ignored.
