The Oxford Handbook of Historical Institutionalism offers an authoritative and accessible state-of-the-art analysis of the historical institutionalism research tradition in Political Science. Devoted to the study of how temporal processes and events influence the origin and transformation of institutions that govern political and economic relations, historical institutionalism has grown considerably in the last two decades. With its attention to past, present, and potential future contributions to the research tradition, the volume represents an essential reference point for those interested in historical institutionalism. Written in accessible style by leading scholars, thirty-eight chapters detail the contributions of historical institutionalism to an expanding array of topics in the study of comparative, American, European, and international politics.
