Migration and cosmopolitanism are said to be complementary. Cosmopolitanism means to be a citizen of the world, and migration, without impediments, should be the natural starting point for a cosmopolitan view. However, the intensification of migration, through an increasing number of refugees and economic migrants, has generated anti-cosmopolitan stances. Using the concept of cosmopolitanism as it emerges from migrant protests likea Sans Papiers, No One Is Illegal, and No Borders, an interdisciplinary group of scholars addresses this discrepancy and explores how migrant protest movements elicit a new form of radical cosmopolitanism.The combination of basic theoretical concepts and detailed empirical analysis in this book will advance the theoretical debate on the inherent cosmopolitan aspects of migrant activism. As such, it will be a valuable contribution to students, researchers and scholars of political science, sociology and philosophy.
