This reference from the Correlates of War Project (COW) gives data on historical and contemporary civil, regional, and intercommunal wars. The book begins with an overview of war studies, reflections on the need for systematic quantitative studies of war over time, and background on the Correlates of War Project (COW). The book then explains how intra-state wars are defined and categorized in the COW project and explains the political aspects of intra-state wars. Data are then presented in sections on global regions. The book’s audience includes political scientists, sociologists, economists, cultural and religious scholars, and social scientists interested in war and economic, social, political, and cultural evolution.
