No more bullets for ETA: the loss of internal support as a key factor in the end of the Basque group’s campaign

The Basque separatist organisation ETA laid down its arms in 2011 after 40 years of an armed campaign for independence. It was not a consequence of political negotiations. The Basque group did not achieve its goals. Yet, it unilaterally decided to end its armed activity forever. This article analyses why and how ETA ended its armed campaign. It clarifies the events from the collapse of the last peace process in June 2007 to the announcement of the definitive end of ETA’s campaign in October 2011. It identifies the causal factors that led the Basque group towards its end. This article contends that the end of ETA’s campaign is a case of transformation triggered by its constituency’s withdrawal of support for the armed struggle. The leadership and social base of the political movement to which ETA belongs concluded that political violence was not effective anymore and, furthermore, was damaging for the Basque pro-independence movement. After an internal struggle, in which the faction advocating for exclusively political means prevailed, ETA was driven towards a unilateral abandonment of armed struggle.
