Globalization and European integration have caused nation states to lose power, while the European Union and regions have gained more influence. As the EU has deepened integration, it has become an independent actor on the global stage, while member states have become more dependent. Some regions are more populous than some EU member states, and regions argue they have historic identities. While decentralization and integration decisions are still controlled by nation states, the EU's enlargement and establishment of institutions like the Committee of the Regions have strengthened the role and influence of regions in the EU project.
