Political tensions in Catalonia have intensified in September 2026. Around the Diada on 11 September, confrontations took place in Barcelona between supporters of the Aliança Catalana and counter-protesters. According to consistent media and official reports, at least three people were arrested; the Mossos d'Esquadra reported that officers had been injured. According to several reports, a photojournalist was attacked during the clashes. The municipal Guardia Urbana put attendance at the large pro-independence rally at tens of thousands.
A week later, the accusation ‘Traidores’ (‘traitors’) came back into focus. The city council of El Prat de Llobregat said on 18 September that graffiti had been found on the façade of the local PSCoffice bearing the words ‘TRAIDORES, CEUTA ES ESPAÑA’. The municipality condemned the vandalism and called for an investigation. Parties associated with the city also described it as an attack on political pluralism.
Facts: The arrests and reports of injuries in Barcelona were reported by public-service and news agency media on 10 and 11 September and were supported by information from the Mossos d'Esquadra. The El Prat de Llobregat city council’s statement about the vandalism is based on a municipal announcement cited in local reporting. Taken independently, the two incidents point to a harsher climate in public debate.
Attributed assessments: In comments by political figures from different camps, the term ‘Traidores’ is used to delegitimise opponents. Representatives of local parties and civil society groups in Catalonia condemned violence and intimidation and called for disavowals of verbal escalation.
Consequences and outlook: In the short term, calls are being made for the police and the courts to investigate acts of vandalism and prosecute offences consistently. Municipal bodies and regional politicians are also demanding clear signals against the coarsening of political language. It remains unclear whether the tensions were merely an accompaniment to the Diada or will intensify the political tone over the long term, and the situation warrants continued monitoring.
The events in Barcelona and El Prat de Llobregat come at a time when heated labels are also gaining currency beyond Catalonia. The widespread use of the word ‘Traidores’ points to a conflict dynamic fuelled by questions of identity politics and territorial references such as the reference to Ceuta. Authorities and municipal bodies urge people to keep debate focused on the issues and protect public spaces from intimidation.
