Book excerpt: This book addresses the impact of migration on the formation and transformation of identity and its continuous negotiations. Its ground is the understanding of identity as a complex social phenomenon resulting from constant negotiations between personal conditions, social relationships, and institutional frameworks. Migrations, understood as dynamic processes that do not end when landing in the host country, offer the best conditions to analyze the construction and transformation of social identities in the postcolonial and globalized societies. Searching for novel epistemologies and methodologies, the research questions here addressed are how identity is negotiated in migration processes, and how these negotiations work in contemporary multiethnic Europe. This edited volume brings to the field a novel convergence of theoretical and empirical approaches by gathering together scholars from different countries of Europe and the Mediterranean area, from different disciplines and backgrounds, challenging the traditional discipline division.
