Mass graves in post-independence Sri Lanka were first reported following the 1971 youth uprising led by the Peoples Liberation Front (known locally as JVP) which was brutally terminated by the then government. However the locations of these post 1971 mass graves are hidden from the public knowledge and hence they are not represented in the above map. Numerous mass graves have been clandestinely created by the Sri Lankan government during the second youth uprising led by the same political party in the 1987-1990 period and locations of these gravesites are illustrated in the map. Virtually all mass graves reported in the northern and eastern provinces of the country were resulted from the thirty year long civil war between the LTTE and the ruling governments which ended in 2009 and said to have contained the remains of minority Tamil speaking people died during the war.
