The snake and the axe: how a student group became a paramilitary force

History · Published 3 October 2026 Swipe more like this →

In short: Founded in 1959 by students seeking Basque independence, ETA evolved from a nationalist movement into a clandestine paramilitary organization. For decades, it waged a violent campaign of bombings and assassinations in Spain and France, ultimately killing over 800 people before ending its armed operations in 2011 and dissolving in 2018.

ETA, or Euskadi Ta Askatasuna, emerged during the Francoist era as a radical departure from the moderate Basque Nationalist Party. Its ideology was a complex, shifting blend of Marxism-Leninism, liberation theology, and ethnonationalism. The group viewed the Spanish state as a continuation of Francoism and sought to establish an independent socialist Basque state. This vision was deeply influenced by figures like Federico Krutwig, whose 1963 book Vasconia helped pivot the movement toward anti-capitalist and anti-imperialist goals. Interestingly, the group’s survival during its early years was bolstered by support from the Basque clergy, who provided safe havens and even stored weapons in religious buildings.

The organization’s structure was highly compartmentalized to evade law enforcement. It operated through small, mobile cells known as taldes, which were coordinated by a central military committee. These units relied on hidden caches called zulos to store explosives and hostages. Over time, the group’s internal hierarchy became increasingly complex, dividing into eleven distinct substructures—including logistics, political negotiation, and treasury—to mitigate the impact of police arrests and infiltration. Despite its militant focus, ETA maintained a political wing, most notably the party Batasuna, which was eventually banned by the Spanish Supreme Court in 2003 for its deep, proven ties to the armed group.

The conflict left a profound scar on the region, with more than 850 people killed and thousands wounded. By the late 1990s and early 2000s, public support for the group’s violent tactics began to wane significantly, accelerated by events like the 1997 kidnapping and murder of Miguel Ángel Blanco. Following years of police pressure and internal shifts, the group declared a permanent end to its armed campaign in 2011. By May 2018, ETA had officially dismantled all its structures, marking the end of a long, violent chapter in European history that had seen the group classified as a terrorist organization by the European Union, the United States, and several other nations.
