2014 Catalan self-determination referendum

A non-binding Catalan self-determination referendum, also known as the Citizen Participation Process on the Political Future of Catalonia, was held on Sunday, 9 November 2014, to gauge support on the political future of Catalonia. While also referred to as "Catalan independence referendum", the vote was rebranded as a "participation process" by the Government of Catalonia, after a "non-referendum popular consultation" on the same topic and for the same date had been suspended by the Constitutional Court of Spain.
