This dissertation examines the role of military intervention in resolving violent and armed conflicts by exploring the historical record of the 20th Century. It identifies the patterns and traits that connect military intervention and conflict resolution, in order to build theory of military intervention consisting of a general logic and set of conditional generalizations. It examines those recurring conceptual and practical factors and characteristics of interventions associated with particular outcomes and, far more important, looks for linkages between military intervention and conflict resolution. In doing so, the study strives to build a body of knowledge that may assist future policy-makers and practitioners. The purpose is to provide an empirically deduced theory of military intervention that may further the current understanding of how armed force contributes to conflict resolution, bridging the intellectual and often practical chasm between the harsh realities of employing military force and the hopes of the conflict resolution community.
