The document summarizes the ethnic conflict between Tamils and Sinhalese in Sri Lanka. It describes how Tamils initially pursued peaceful federalism but formed the militant LTTE after being rejected. Violence escalated between both groups throughout the 1950s-1980s. The 1983 riots caused thousands of deaths and displaced Tamils. Foreign intervention by India in the late 1980s failed to achieve lasting peace. Tensions and hostilities between Tamils and the Sinhalese government continued into the 1990s.
