The Causes of War

"Provides good summaries of a wide range of debates in conflict theory alongside a diverse array of historical
material and case studies. The book commends itself to the attention of researchers, advanced undergraduates and postgraduates in the field of international relations theory, security studies and peace and conflict studies."
Acta Politica

"A fine overview of the major factors influencing decisions for interstate war – power, democratic peace, and trade – across different levels of analysis. The inclusion of frequent case applications and a discussion of civil war are bonuses."
Paul F. Diehl, University of Illinois
