At the beginning of the 1990s, a wave of democratization raised new hopes for peace in Africa, but as the decade progressed, violent politics spread and formed two large arcs of conflict that weakened or even collapsed states could not contain. This review article examines five recent books that address the potential impact of identity politics on civil violence in Africa. Two of the authors—Donald Horowitz and Ted Gurr—address these issues in a global comparison, while the other three—Luis Martinez, Stephen Ellis, and Mahmood Mamdani—examine important African instances of protracted internal warfare, in Algeria, Liberia, and Rwanda, respectively. Is identity politics the primary instigator of disorder? What is die impact of a prolonged period of state crisis upon communal relationships? The volumes under review offer useful insights, but large questions remain.
