The Lapita people, named after their distinctive pottery style, were the first people to inhabit Fiji in about 3000 BCE, and evidence of their settlements exist throughout Fiji – particularly around the Sigatoka Sand Dunes. They were followed by the Melanesians in about 500 BCE, and relatively recent trading with the Polynesian Tongans has added to the cultural mix. In the Lau group of islands, aspects of both cultures still intermingle. There was active commerce between Tonga and Fiji, and later in the history of this relationship, the Fijians in the Lau Islands (Eastern Fiji) became vassals to the King of Tonga. One particular reason Tongans and Samoans came to Fiji was to build the Drua (large double-hulled canoes) which they couldn't build on their own islands because of the lack of proper timber.
