Catalonia's pro-independence parliament passed the Law on the Referendum on Self-determination of Catalonia on 6 September 2017, despite the Spanish government declaring such a vote a breach of the constitution. Spain's Constitutional Court suspended the referendum on 7 September, and courts ordered police to prevent it from taking place.
On 1 October 2017, the Generalitat de Catalunya held the referendum, asking voters whether Catalonia should become an independent republic. Spanish National Police and Civil Guard raided polling stations, clashing with voters, while the regional Mossos d'Esquadra largely stood aside. The 'Yes' side won 90.18% but turnout was only 43.03%, and international observers found the process fell short of minimum election standards.
The Constitutional Court voided the referendum law on 17 October 2017. Spanish authorities subsequently prosecuted senior Catalan independence leaders, and the Spanish government invoked Article 155 of the constitution to impose direct rule over Catalonia, prompting a prolonged constitutional and political standoff between Madrid and the Catalan government.
Political Outcome
The 'Yes' side won 90.18% of votes, but the referendum was declared void and unconstitutional by Spain's Constitutional Court; Catalan independence was not achieved.
Catalonia governed as an autonomous community under the Generalitat de Catalunya
Spanish government imposed direct rule under Article 155 of the constitution following the crisis
