Independence movement

In November 2003, elections to the Parliament of Catalonia gave the government to a left-wing Catalanist coalition formed by the Socialists' Party of Catalonia (PSC-PSOE), Republican Left of Catalonia (ERC) and Initiative for Catalonia Greens (ICV), and the socialist Pasqual Maragall was appointed president. The new government redacted a new version of the Statute of Autonomy, with the aim of consolidate and expand certain aspects of self-government.

The new Statute of Autonomy of Catalonia, approved after a referendum in 2006, was contested by important sectors of the Spanish society, especially by the conservative People's Party, which sent the law to the Constitutional Court of Spain. In 2010, the Court declared non-valid some of the articles that established an autonomous Catalan system of Justice, improved aspects of the financing, a new territorial division, the status of Catalan language or the symbolical declaration of Catalonia as a nation. This decision was severely contested by large sectors of Catalan society, which increased the demands of independence.

A controversial independence referendum was held in Catalonia on 1 October 2017, using a disputed voting process. It was declared illegal and suspended by the Constitutional Court of Spain, because it breached the 1978 Constitution. Subsequent developments saw, on 27 October 2017, a symbolic declaration of independence by the Parliament of Catalonia, the enforcement of direct rule by the Spanish government through the use of Article 155 of the Constitution, the dismissal of the Executive Council and the dissolution of the Parliament, with a snap regional election called for 21 December 2017, which ended with a victory of pro-independence parties. Former President Carles Puigdemont and five former cabinet ministers fled Spain and took refuge in other European countries (such as Belgium, in Puigdemont's case), whereas nine other cabinet members, including vice-president Oriol Junqueras, were sentenced to prison under various charges of rebellion, sedition, and misuse of public funds. Quim Torra became the 131st President of the Government of Catalonia on 17 May 2018, after the Spanish courts blocked three other candidates.

In 2018, the Assemblea Nacional Catalana joined the Unrepresented Nations and Peoples Organization (UNPO) on behalf of Catalonia.

On 14 October 2019, the Spanish Supreme court sentenced several Catalan political leaders, involved in organizing a referendum on Catalonia's independence from Spain, and convicted them on charges ranging from sedition to misuse of public funds, with sentences ranging from 9 to 13 years in prison. This decision sparked demonstrations around Catalonia. They were later pardoned by the Spanish government and left prison in June 2021.

In the early-to-mid 2020s support for independence declined.
