'This deeply researched study offers a refreshing perspective on global constitutionalization, a topic that is garnering increasing attention in the international law and international relations literature. Milewicz's rigorous approach convincingly shows that the international processes of constitutionalization are driven by powerful democratic states and raises important questions about the future direction of global governance.' Alexandru Grigorescu, Loyola University Chicago 'In Constitutionalizing World Politics, Karolina Milewicz skillfully weaves conceptual and empirical insights from political science to create a theoretically grounded and empirically informed model for understanding when and why constitutionalization occurs. In so doing, this impressive volume develops a powerful and innovative approach to understanding whether, and how, states' participation in a dense web of international treaties and law-making processes is contributing to a constitutionalization of the international order.' Jeffrey Dunoff, Laura H. Carnell Professor of Law, Beasley School of Law, Temple University, Philadelphia 'The book will be an excellent addition to collections on international law and politics, as well as those on human rights.'
