Some nation states of Europe which have historically had a strong centralized administration have transferred political power to the regions. Examples of this include the devolution of power in the UK. The European Union created a Committee of the Regions to represent Regions of Europe as the layer of EU government administration directly below the nation-state level in order to strengthening the political and economic situation in those regions.
Some regions in Europe have joined forces and created Euroregions. Example of regional cooperation among member states include: Galicia-North Portugal Euroregion (Spain-Portugal), Helsinki-Tallinn Euroregion (Estonia-Finland), Black Sea Euroregion (Bulgaria-Romania) and Euroregion Baltic (Denmark-Lithuania-Poland-Russia-Sweden).
