This book analyses the rise and decline of the Basque terrorist group Euskadi Ta Askatasuna (ETA, Basque Homeland and Freedom). ETA declared a unilateral ceasefire in November 2011, bringing to a close a campaign of political violence that started in the late 1960s. By the beginning of the twenty-first century, the overwhelming majority of secession supporters agreed that an independent Basque homeland would be realised through ‘ballots’ and not ‘bullets’.
