Thiruvenkadam Velupillai Prabhakaran ( listen (Tamil: வேலுப்பிள்ளை பிரபாகரன்; November 26, 1954 – May 18, 2009) was the founder and leader of the Liberation Tigers of Tamil Eelam (the LTTE or the Tamil Tigers), a militant organization that sought to create an independent Tamil state in the north and east of Sri Lanka. For over 25 years, the LTTE waged a violent secessionist campaign in Sri Lanka that led to it being designated a terrorist organization by 32 countries. Founded in 1976, the LTTE rocketed to prominence in 1983 after they ambushed a patrol of the Sri Lanka Army outside Jaffna, resulting in the deaths of 13 soldiers. This ambush, along with the subsequent rioting which resulted in the deaths of hundreds of Tamil civilians, is generally considered the start of the Sri Lankan Civil War. After years of fighting, including the unsuccessful intervention of the Indian Army, the conflict was halted after international mediation in 2001. By then, the Tamil Tigers controlled large swathes of land in the north and east of the country, running virtually a mini-state with Prabhakaran serving as its unquestioned leader. Peace talks eventually broke down, and the Sri Lanka Army launched a military campaign to defeat the Tamil Tigers in 2006. Prabhakaran was killed in fighting with the Army on May 18, 2009. It was alleged that his 12-year-old son was executed a short time later. His death brought an immediate end to the Civil War.
