David Laitin has explained the occurrence of Basque and Georgian nationalistviolence as the outcome of language revival in a bilingual setting and aspecific locale. Based on game theory, he has suggested that violence, as arational nationalist strategy, will increasingly be used if specific thresholdslevels in language choice for education are met. A critical reappraisal of hisapproach is made in which the conceptual and methodological limits to theempirical testing are highlighted. Subsequently, an extensive dataset of Basquemunicipalities in the Autonomous Community of the Basque Country is used tostatistically verify Laitin’s model by multivariate analysis. In someareas of the Basque Country Laitin’s model seems to fit while inothers not. With the help of both quantitative and qualitative data, alternativeexplanations for Basque ethnic violence are explored.
