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.
2017 Catalan regional election
After independence was declared by the Parliament of Catalonia on 27 October and Prime Minister Mariano Rajoy announced the Parliament's dissolution and a regional election for 21 December, pro-independence parties debated whether they should contest the election–thus abiding by Spanish law, and acknowledging independence did not take place–or boycott it and thus risk remaining absent from the Parliament in the next legislature.
