The PR exterior of the EU gives as a shiny veneer of union of nations but underneath lies a history of separatist movements each striving for self-determination and freedom from central governments and decision makers, which minority territories feel that do not represent them. Here's a map of currently active separatist movements in Europe.

Red names indicate regions with movements that only claim greater autonomy within the actual state. Black names indicate regions with important secessionist movements, although both categories include moderate movements. The nations highlighted in colors are the territories claimed by the local nationalist groups, including areas out of the state's borders and cases of annexation to other states.
