Catalan Way
Catalonia saw several local referenda for independence take place in hundreds of villages between 13 September 2009 and April 2011, with an overwhelming number of "yes" votes being cast.
The 2012 Catalan independence demonstration, organized by the Catalan National Assembly, argued that Catalonia should become an independent state within the European Union, under the slogan "Catalonia, new state in Europe". The number of participants was estimated at about 1.5 million according to Barcelona's Municipal Police and Catalonia's Department of the Interior, about 2 million according to the organizers, and about 600,000 according to the delegation of the Spanish government in Catalonia.
Self-determination
Almost three years later (1 October 2017), the Catalan government called a referendum for independence under legislation adopted in September 2017 (despite being blocked by the Constitutional Court of Spain), with the question "Do you want Catalonia to become an independent state in the form of a Republic?". On polling day, the Catalan police prevented voting in over 500 polling stations, without incident, while the Spanish police confiscated ballot boxes and closed down 92, with several incidents involving truncheon charges, the closure of some voting centres and the seizure of ballot boxes. The opposition parties had called for non-participation. The turnout (according to the votes that were counted) was 2·3m out of 5·3m (43·03% of the census), and 90·18% of the ballots were in favour of independence. The turnout, ballot count and results were similar to those of the 2014 "consultation".
