This report analyses the role of global arms trade in civil wars, focusing specifically on Sri Lanka. The war between the Sri Lankan government and the Liberation Tigers of Tamil Eelam (ltte) was one of the world’s most violent and long-lasting armed conflicts. An estimated 84 000 people lost their lives, while hundreds of thousands were displaced. Severe human rights abuses accompanied the armed conflict, which started in 1983 and ended with a government military victory over the ltte in 2009 – a victory that, however, did not end the underlying conflicts that had caused the war.
