The Eelam Revolutionary Organisation of Students (EROS), also known as the Eelam Revolutionary Organisers, is a former Tamil militant group in Sri Lanka. Most of the EROS membership was absorbed into the Liberation Tigers of Tamil Eelam (LTTE) in 1990. The other half of EROS that did not join forces with the LTTE due was led by PLO trained Shankar Rajee, Senior politburo member and military commander of EROS from 1990 until his demise in 2005. The political wing of 'EROS' is known as the Eelavar Democratic Front. Origins The EROS was formed in London in 1975 by Arul Pragasam, Eliyathamby Ratnasabapathy, V. Balakumaran, Nesadurai Thirunesan (aka Shankar Rajee) and Balanadarajah Iyer (aka Sinna Bala). It started as a think-tank, strongly influenced by Marxism, to analyse Tamil issues. Much of its early membership was drawn from the eastern districts of Batticaloa and Amparai, and also the Jaffna peninsula. EROS was the first political group which recruited Sri Lankan Muslims as well and was more concerned with the question of the Sri Lankan Muslims than any other group had been. They drew up a four phase programme to co-opt the Tamil-speaking Muslims of the eastern province into the Eelam struggle, by working closely with them, and understanding and espousing their grievances. Links with Palestinians In 1976, the EROS established links with the Abu Jihad of the Palestine Liberation Organization (PLO) and began planning the setting up of camps to train Sri Lankan Tamils in military and guerrilla warfare. EROS even opened up their training camp for the LTTE where Velupillai Prabhakaran had his initial training. The Tamil Eelam Liberation Organization (TELO), Eelam People's Revolutionary Liberation Front (EPRLF) and People's Liberation Organisation of Tamil Eelam (PLOTE) sent their own men to the PLO's camps for training under the request of EROS, and EROS also organised for men of other groups to be sent. A number of Tamils, including many who would later form the core of the other Tamil militant groups, started their militant careers in these camps. Splinter groups Despite being the most ideological of all the Tamil groups, and its strong revolutionary nationalism, the EROS never became as militarily active as later groups such as the LTTE or TELO, largely because its leadership continued to be based in London. Their most notable military actions was the bombings in Sri Lanka in 1984 and 1985, and the kidnapping of British journalist
