This volume, prepared in conjunction with the academic course European Integration at the Turn of the Twentieth and Twenty-first Century, features a collection of papers delivered during a series of lectures and seminars organized by the Faculty of International Studies and Political Science at the University of Lódz from 2011 to 2014. Some essays in the volume argue that the European Union is the most successful model of supranational governance since the rule of history's largest empires. Other works focus on various aspects of the European Union that have contributed to almost ten years of crisis.
