Scholars from political science and law examine the latest research on the constitutionalization of politics in comparative perspective. The scope includes both inter- country and intra- country perspectives, institutional and systemic analyses, common and civil law systems, focusing on historical and contemporary case studies. There are chapters limited to a concrete legal and political system, analyzing the tools and processes guarding constitutionalization of politics in such countries as the United States, Germany, France, Italy, Poland, Finland, and Bulgaria, as well as studies offering comparative analysis of various institutions representing different countries and different legal and political systems. Taken together, this book uncovers a wide variety of legal and political cultures, systems of governments, and forms of territorial organization. Once uncovered, this approach makes it easier to determine repetitive patterns which may be observed in constitutional review and constitutional interpretation, or significant differences occurring in the models of constitutionalization of politics around the world. Constitutionalization of Politics in Comparative Perspective tackles important debates among academics interested in the theoretical and practical aspects of constitutions and constitutionalism and will appeal to social scientists, including sociologists, philosophers, security studies and international relations experts but also cultural studies scholars. The publication is a result of a research project "Constitutionalization of Politics as an Element of Checks and Balances System in Comparative Perspective" funded by the Polish National Science Center (NCN, 2018/31/B/HS5/02637).
