Book excerpt: Constitutional politics is exceptionally intense and unpredictable. It involves negotiations over the very nature of the state and the implications of self- determination. Multinational democracies face pressing challenges to the existing order because they are composed of communities with distinct cultures, histories, and aspirations, striving to coexist under mutually agreed-upon terms. Conflict over the recognition of these multiple identities and the distribution of power and resources is inevitable and, indeed, part of what defines democratic life in multinational societies. In Constitutional Politics in Multinational Democracies André Lecours, Nikola Brassard-Dion, and Guy Laforest bring together experts on multinational democracies to analyze the claims of minority nations about their political future and the responses they elicit through constitutional politics. Essays focus on the nature of these states and the actors and political process within them. This framework allows for a multidimensional examination of crucial political periods in these democracies by assessing what constitutional politics is, who is involved in it, and how it happens. Case studies include Catalonia and Spain, Puerto Rico and the United States, Scotland and the United Kingdom, Belgium, Bosnia and Herzegovina, and Quebec and the Métis People in Canada. Theoretically significant and empirically rich, Constitutional Politics in Multinational Democracies is a necessary read for any student of multinationalism.
