The aim of this publication is to reflect, conceptually and empirically, on border processes in Europe, paying special attention to the most current border-related developments, with a special focus on the processes of de-bordering and re-bordering. As the authors represent different academic centers and specializations, the volume reflects not only diverse perspectives but also has an interdisciplinary character. The book contains eight contributions and is divided into three thematic parts. The first set of chapters analyzes the borders and borderlands of the European Union, especially in the context of the ongoing changes observed in its direct neighborhood. The next group of articles deals with the regional level of border-related processes within the European Union. Finally, the last group of texts investigates border processes at the local level, analyzing border urban structures.
