After Sri Lanka became independant in 50's the buddhist monks there became prominent in govt policy making. The tamils were the most affluent section of the society and the majority Sinhalese felt alienated. They started reservation for the majority sinhalese in all govt jobs, colleges, schools, army, police, governance etc. They imposed restriction on trades in Jaffna and crippled the economy there. Jaffna and Colombo were two thriving cities in 50's. Tamils were protesting peacefully against the injustice for 30 years from 50's to 80's. After ethnic cleansing of tamils in 1979, the militant outfit of LTTE was formed. Prabhakaran was trained and supported by Indira Gandhi and MGR. There were several tamil outfits in Sri Lanka getting funds from abroad. Prabhakaran murdered all the rival tamil outfits and their leaders to divert all the funds to LTTE alone. Rajiv Gandhi made a tactical error in sending Indian troops to Sri Lanka for peace keeping. They ended up fighting with the LTTE causing major casualities on both sides. Sri lankan govt broke the peace accord days ater the Indian troops landed there. LTTE used this to assasinate Rajiv Gandhi as revenge, this further alienated their force in India. Only a small portion of tamils in TN support LTTE. Majority of tamils sympathize with sri lankan tamils but are against the LTTE. Only the old and the poor tamils still remain in SL, most of them moved away from the country now. Eventually the sinhalese will wipeout tamils.
