This edited volume provides a solid yet accessible set of contributions for students, specialists and practitioners of federalism. It also reflects a commitment to normalising the connection between federal studies and scholarship on pluralism and diversity management. To shed light on a specific theme through a rigorous and comprehensive approach, most chapters compare at least two federal systems in connection with a given institutional matter or area of public policy.  Acknowledgements The editors of the volume would like to extend their warmest thanks to the Programme d'appui à la recherche of the Secrétariat du Québec aux relations canadiennes, the Groupe de recherche sur les sociétés plurinationales, the Centre d'analyse politique – Constitution et fédéralisme, and the Canada Research Chair in Quebec and Canadian Studies. This project would not have been possible without their most generous support. The editors would also like to thank the entire editorial team at Palgrave Macmillan. In particular, they are grateful to Soeren Keil and Eva Maria Belser, who enthusiastically welcomed the present project into their Federalism and Internal Conflicts series, and to Ambra Finotello, Hemapriya Eswanth and Zeenathul Raeesa Ismail for their editorial support. They would also like to thank the anonymous reviewers who helped to improve the overall quality of this collective work. - Félix, Dave, and Alain
