In Spain, the 1978 Constitution was the legal outcome of a political transition to a democracy, following the horrors of civil war and dictatorship. Among other things, it established a territorial model – the so-called “Estado de las Autonomías” (State of Autonomous Communities) – which was in principle designed to satisfy the historical demands for recognition and self-government of, above all, the citizens and institutions of two minority nations: Catalonia and the Basque Country. This territorial model occupies an intermediate position between the classic federal and regional models of comparative politics, but has more regional than federal features. Yet thirty-six years later, many Catalan and Basque citizens and political and social actors show a deep disappointment regarding the development of this territorial model – in terms of collective rights, political recognition and self-government.

Those in favour of independence had been in the minority throughout the 20th century. Nowadays, however, demands of a pro-autonomy and pro-federalist nature, which until recently had been dominant, have gradually lost public support in favour of demands for self-determination and secession. The following graph shows this recent trend.
