As the example of the “Berlin Wall” illustrates, the 20th century can be understood as an age of failed attempts to regulate, steer and control cross-border migration movements with the help of national migration policies. At the end of the 20th century, globalization makes the attempt to shape migrations by means of national migration policies finally seem obsolete. But what can take their place in the face of migratory pressures that many in Europe subjectively perceive as increasingly frightening? This question demands new answers from political decision-makers and a rejection of old dogmas. To this end, the anthology provides numerous suggestions by illuminating the new dimensions of migration in and to Europe in various contributions by recognized migration experts and proposing adequate responses. The results of this volume are just as interesting for economists, lawyers and political scientists who deal with questions of migration in Europe on an interdisciplinary basis as they are for political actors.
