 There has been a "real decentralisation of power", at the expense of an "enormous and confusing variety of autonomy statutes".Eight of the Autonomous Communities (Andalucia, Aragon, Basque Country, Canary Islands, Catalonia, Galicia, and Valencia) are officially designated as "nationalities", while the rest are defined as regions, historical regions, communities and historical communities.The designation as a "nationality" was originally confined to the "historic nationalities" of Catalonia, the Basque Country, and Galicia, which were selected to receive a greater degree of autonomy sooner, but later amendments have increased the autonomy of most other regions as well.
