The Arab protest movements of 2010-2011 gave momentum and inspiration to unprecedented political mobilisations of migrants of Arab origin, whether first generation, second generation, or more, in Europe, North and South-America. This book analyses the essential yet understudied role of Arab diasporas during the Arab revolutions, dissecting the new forms of diasporic mobilisations that emerged during the ‘Arab Spring’ and that were borrowed as much from the home countries’ repertoire of innovations as from global movements’ tactics from Wall Street to Sao Paulo. This collection is a very timely and much-welcome contribution to our understanding of the nexus between immigration and integration. At a time when the engagement of European youth in faraway violent conflicts is hitting the headlines all over Europe, this book offers balanced and renewed academic perspectives on migrants belonging, analysing how migrants use political engagement to assert their belonging in newly-imagined home countries and, conversely, how they get involved in the politics of their origin countries to bolster their identity in host nations.
