The largest ethnic group is Sinhalese (74%), followed by Sri Lankan Tamils (12%), Indian Tamils (5%), Muslims (7%), minorities of Malays and Burghers (persons of Dutch or partly Dutch descent) and a small number of Veddhas, descended from the earliest inhabitants. Sinhalese settlers arrived in the 5th and 6th centuries BC. Sri Lankan Tamils settled mainly from the 10th century onwards. Indian Tamils arrived later, brought in by the British in the 19th century as labour for the plantations. Some Indian Tamils were repatriated from 1964, and since 1988 all remaining Indian Tamils have attained Sri Lankan citizenship. The Muslims are mostly descendants of Arab traders, and the Burghers descendants of European settlers of the 17th century onwards.
