evidence: The first Sinhalese arrived in Sri Lanka late in the 6th century B.C., probably from northern India. Buddhism was introduced circa 250 B.C., and the first kingdoms developed at the cities of Anuradhapura (from about 200 B.C. to about A.D. 1000) and Polonnaruwa (from about A.D. 1070 to 1200). In the 14th century, a South Indian dynasty established a Tamil kingdom in northern Sri Lanka. The Portuguese controlled the coastal areas of the island in the 16th century, followed by the Dutch in the 17th century. The island was ceded to the British in 1796, became a crown colony in 1802, and was formally united under British rule by 1815. As Ceylon, it became independent in 1948; the name was changed to Sri Lanka in 1972. Prevailing tensions between the Sinhalese majority and Tamil separatists erupted into war in 1983. Fighting between the government and Liberation Tigers of Tamil Eelam (LTTE) continued for over a quarter-century. Although Norway brokered peace negotiations that led to a cease-fire in 2002, the fighting slowly resumed and was again in full force by 2006. The government defeated the LTTE in 2009.
