Catalan Independence Movement

The Catalan independence movement (independentisme català) is a long-running political and cultural movement in the autonomous community of Catalonia in northeastern Spain. While Catalan nationalism has roots in the 19th-century Renaixença cultural revival and the short-lived Catalan Republic proclaimed in 1931, modern pro-independence sentiment surged sharply after Spain's Constitutional Court in 2010 struck down core provisions of the 2006 Statute of Autonomy of Catalonia, which had been approved by Catalan voters in a referendum.

Mass demonstrations organized annually on La Diada (11 September) by groups such as the Assemblea Nacional Catalana (ANC) and Òmnium Cultural became a fixture from 2012 onward. A non-binding consultation was held in November 2014 under regional president Artur Mas, despite opposition from Madrid. The movement reached its peak crisis on 1 October 2017, when the Generalitat under Carles Puigdemont staged an independence referendum that Spain's Constitutional Court had suspended; the vote was marked by police violence against voters. On 27 October 2017, the Catalan Parliament declared independence, prompting the Spanish government under Mariano Rajoy to invoke Article 155 of the Constitution for the first time, suspending Catalan autonomy and calling new regional elections.

Several Catalan leaders, including Oriol Junqueras, were convicted of sedition and misuse of public funds in 2019 by the Spanish Supreme Court and later pardoned by the Pedro Sánchez government in 2021. Puigdemont fled to Belgium and remained the subject of European Arrest Warrant proceedings. In 2024, the Spanish Congress passed a controversial Amnesty Law covering acts linked to the procés, in exchange for parliamentary support from Junts and ERC.

Key parties include Esquerra Republicana de Catalunya (ERC), Junts per Catalunya, and the far-left CUP. Public support for independence, measured by the Centre d'Estudis d'Opinió, has fluctuated and declined from its 2017 peak.
