This Handbook covers all major aspects of EU Cohesion policy, one of the most significant areas of intervention of the European Union. Over five parts, It discusses this policy's history and governing principles; the theoretical approaches from which it can be assessed; the inter-institutional and multi-level dynamics that it tends to elicit; its practical implementation and impact on EU member states; its interactions with other EU policies and strategies; and the cognitive maps and narratives with which it can be associated. An absolute must for all students of the EU.
