"The Jardun militants are the most dangerous," confirms a police source who during the last decade has monitored the evolution of the dissidence of the official nationalist left controlled by Arnaldo Otegi and Herri Batasuna leaders such as Sonia Jacinto and Floren Aoiz, now candidates for the Senate on 29N. Without cards, or headquarters, not even with their own symbols that identify them in their protests and street attacks, the police accusation of a crime of terrorism against two members of Jardun represents an enormous qualitative leap for this group of nationalist militants that emerged six years ago and that competes with the Gazte Koordinadora Socialista (GKS) and Ernai (Sortu) for the recruitment of young radical sovereignists.
There are no police reports capable of quantifying how many young people are part of the most violent organization of the three that compete for leadership among nationalist youth. Jardun and GKS were created - in very different ways - as currents critical of the decision adopted by Herri Batasuna to abandon the terrorist strategy in which ETA was the striker of the Basque National Liberation Movement (MLNV) while Ernai is the instrument of Sortu - the legal acronym of the Abertzale left - to maintain its influence among the Basque youth sectors. Since its birth as an organization in August 2020, Jardun attracted the toughest dissident militants and inherited political slogans such as amnesty for all prisoners that had promoted the creation of Amnestia eta Askatasuna (ATA), the first group that visualized a possible break in the nationalist left conglomerate after ETA's declaration to cease terrorist violence in its public statement on October 20, 2011.
The two most important currents of critical dissidence with the political evolution articulated through EH Bildu have followed parallel paths, coinciding in some protests but without exhibiting any public confrontation. A tacit pact very different from the constant pulse and sometimes bordering on the violent confrontation between GKS and Ernai that came to dispute occupied venues used as gaztetxes and that maintain an open battle for festive spaces, especially in Bilbao and Vitoria. A duel that, for the moment, Ernai has won by preventing GKS from placing its txoznas at the festivals of the two Basque capitals, limiting its visibility among the youngest and blocking the income obtained in these festive booths.
Jardun and its upcoming brands Jarki and Aske have stayed out of this duel between GKS and Ernai to focus their implementation among the most violent followers of the Euskadi and Navarra football teams. The Jardun militants share an aggressive aesthetic (black clothing, very short hair, branded sneakers or military boots) and stand out in the mobilizations they have shared with GKS sympathizers. The Ertzaintza confirmed its leadership in the serious incidents that took place on October 12, 2025 in Vitoria and also during the attacks suffered by La Roja fans in Bilbao in the run-up to the final between Spain and Argentina on July 19.
In Vitoria, Jardun militants launched an attack against the supporters of the Spanish Falange concentrated in the Plaza de la Provincia, which became the excuse to subdue the Ertzaintza, surprised by the virulence of the radicals. During the previous night, the young Abertzales placed material with which to attack the Ertzaintza (stones, bottles and glasses), they were distributed in black bloc (autonomous groups under a leadership) and the functions of logistics and attack were distributed to the Ertzainas who had to protect the Falange sympathizers while they were attacked by the Abertzainas. Twenty police officers were injured during the almost three hours that the clashes lasted in the heart of the capital of Euskadi.
