The Global Promise of Federalism honours the life and work of Richard Simeon, one of Canada's foremost experts on federalism. It features a group of distinguished scholars of federalism from Canada and abroad who take up some of the fundamental questions at the heart of both Simeon's work and contemporary debates. Does federalism foster democracy? Can it help bring together divided societies? How do federations evolve and adapt to changing circumstances? In the course of answering these questions, the chapters in this collection offer a comparative perspective on the challenges and opportunities facing well-established federations such as Canada and Australia, as well as new federal and quasi-federal systems in Europe, Africa, and Asia. They examine the interplay between federal values, such as trust and mutual recognition, and institutional design; the challenges facing post-conflict federations; and the adaptability of federal systems in the face of changing social, economic, and cultural contexts.
