Abstract
In this article, Spain’s system of autonomous communities as a model of regionalisation in terms of subnational integration is analysed regarding its historical background, legal framework, and political context. Regionalism is examined with special emphasis on Bask nationalism and is also discussed with reference to the recent independence movement taking place in Catalonia. The contribution of the European Union’s encouragement of regional self-government to the development of regional democracy in Spain is stated in the mentioned as well. Regionalisation in Spain is important as the discussion on 2017 independence referendum in Catalonia continues to be relevant. Being within unitary state level the regionalised state model strengthened the integration of the historical nationalities/regions with Spain and soothed the influence of the separatist movements; however, with the recent rally of Catalan nationalism this model became a controversial topic.
