While most research on the Tamil diaspora and the conflict in Sri Lanka studies the Tamil diaspora in the United Kingdom and Canada, this article focuses on the role of organized Tamils in Germany. Based on an extensive three years of qualitative field study in Germany and Sri Lanka, and using the theoretical framework of Bercovitch's (2007) conflict cycle, I analyzed the engagement of the Tamil diaspora in Sri Lanka in three phases of the conflict: conflict emergence before the war (until 1983), conflict escalation and the war (1983–2009), and post-conflict reconstruction after the war (from 2009). In each of these phases, they took different positions toward the conflict. Before the war, German Tamil organizations were reluctant to get involved in the conflict. During the war, some Tamil diaspora organizations in Germany were involved in the war to a minor degree by their active membership and political participation in larger umbrella organizations initiated by the Tamil militant organization called Liberation Tigers of Tamil Eelam (LTTE). The larger part of the diaspora focused on self-initiated and independent social development projects in Sri Lanka. After the LTTE lost the war, the second generation of Tamils took over leadership positions in the diaspora in Germany and focused on new social and health projects in Sri Lanka.
