Catalonia might be the separatist region making headlines at the moment but Europe has many other separatist movements that are closely watching developments in northeastern Spain.
Separatist movements in Europe can range from small townships to entire regions and the motivations for wanting to go it alone are equally as diverse encompassing linguistic and cultural differences as well as economic and historical justifications. While some separatist movements harbor dreams of gaining just a bit more autonomy from the national government, others like Catalonia are aimed at gaining full independence and nothing less.
Countries like Germany and Italy where states can have very distinct linguistic, cultural and historical differences tend to have numerous and significant separatist movements to contend with. Geographical characteristics can play a part too with islands — such as Sicily or the Faroe Islands (between Norway, Scotland and Iceland) — and peninsulas (such as Cornwall, in southwest England) often seeking more autonomy or independence, feeling "separated" and far from the centers of power.
