Was the Basque conflict a war for independence or a struggle against criminal terrorism?

In short: For over five decades, the Basque Country was the site of modern Western Europe's longest-running violent conflict. While separatist militants sought independence through an armed campaign, the Spanish state viewed the violence as a criminal matter. The legacy of this era remains deeply contested, shaping Spanish and Basque politics today.

The conflict began in 1959 with the formation of ETA, a group initially inspired by anti-colonial liberation movements. Its roots were deeply embedded in the trauma of the Spanish Civil War and the subsequent decades of the Franco dictatorship, which suppressed Basque language and culture. For many, ETA’s early actions were seen as resistance against an authoritarian regime. However, as Spain transitioned to democracy in the late 1970s, the nature of the violence shifted. ETA continued its armed campaign against the new constitutional state, leading to its bloodiest period between 1978 and 1981, when more than 230 people were killed.

The conflict was characterized by a complex cycle of violence. ETA targeted politicians, journalists, and security forces, while the Spanish state responded with counterinsurgency operations. During the 1980s, the state-backed Grupos Antiterroristas de Liberación (GAL) operated as death squads, killing 27 people in a period often called the Spanish Dirty War. Simultaneously, far-right paramilitary groups were active, carrying out attacks against suspected nationalists. This era of state-sponsored violence remains a point of intense debate, with some arguing it undermined the very rule of law the government claimed to defend.

The terminology remains a battleground. Basque nationalists often frame the situation as a political conflict over self-determination, comparing it to the peace processes in Northern Ireland or South Africa. Conversely, many Spanish officials and citizens reject this narrative, viewing ETA’s actions as pure terrorism. This disagreement extends to the present, where the legacy of the conflict influences how the Basque Country’s high level of autonomy is perceived. While ETA announced a definitive end to its armed activity on 20 October 2011, the debate over whether the conflict was a war or a criminal campaign continues to divide public memory and political discourse in Spain.
