Involvement was particularly strong in the Indian state of Tamil Nadu, where ethnic kinship led to strong support for the independence of Sri Lankan Tamils. Throughout the conflict the Indian central and state governments supported both sides in different ways. From August 1983 until May 1987 the Indian government, through its intelligence agency Research and Analysis Wing (RAW), provided arms, training and monetary support to six Sri Lankan Tamil militant groups including LTTE, Tamil Eelam Liberation Organization (TELO), People's Liberation Organisation of Tamil Eelam (PLOTE), Eelam Revolutionary Organisation of Students (EROS) Eelam People's Revolutionary Liberation Front (EPRLF) and Tamil Eelam Liberation Army (TELA). LTTE's rise is widely attributed to the initial backing it received from RAW. It is believed that by supporting different militant groups, the Indian government hoped to keep the Tamil independence movement divided and be able to exert overt control over it.
