Together with politics, economics and religion, war is one of the fundamental factors that can shape a society and group identities. In the prehistoric world, the sources for the study of war are disparate and their interpretation can be inconsistent and problematic. In the case of Crete in the Bronze Age, a systematic analysis of the evidence will be undertaken for the first time in this paper, and this opportunity is used to critically evaluate the most effective ways of employing the widely agreed sets of physical correlates for ancient war in the archaeological record. A further objective in exploring the diachronic roles of war in these societies is to move the discussion from a niche field to a more integrated, and systematic, social analysis. The existence and character of a warrior identity is examined, and it is proposed that it often constituted a conspicuous element of male identity. The varying scales and time spans through which war can influence a society are discussed, and a broad framework for understanding war in social process, practices and events is proposed.
