iTaukei, legally known until 2010 as Fijians, are the major indigenous people of the Fiji Islands, and live in an area informally called Melanesia. Indigenous Fijians are believed to have arrived in Fiji from western Melanesia approximately 3,500 years ago, though the exact origins of the Fijian people are unknown. Later they would move onward to other surrounding islands, including Rotuma, as well as blending with other (Polynesian) settlers on Tonga and Samoa.
