Pottery excavated from Fijian towns shows that Fiji was settled before or around 3500–1000 BC, although the question of Pacific migration still lingers. It is believed that the Lapita people or the ancestors of the Polynesians settled the islands first but not much is known of what became of them after the Melanesians arrived; they may have had some influence on the new culture, and archaeological evidence shows that they would have then moved on to Tonga, Samoa and Hawai'i. In 1970 Fiji was granted Independence by Great Britain.
