In The Identity of Nations, Montserrat Guibernau engages in the current debates about the extent to which multiculturalism still offers a valid integration model and the challenges of preserving national identities and cohesion while promoting and incorporating ethno-cultural diversity. Her book essentially argues that national identities remain strong and act as a powerful political mobiliser despite being transformed by the impacts of devolution (for example, in Quebec, Catalonia, Scotland and Wales), European integration and migration.
