Tikopia is a small high island in the southwestern Pacific Ocean. It is part of the Solomon Islands of Melanesia, but is culturally Polynesian. The first Europeans arrived on 22 April 1606 as part of the Spanish expedition of Pedro Fernandes de Queirós.
Covering an area of 5 square kilometres (1.9 square miles), the island is the remnant of an extinct volcano. Its highest point, Mt. Reani, reaches an elevation of 380 metres (1,250 feet) above sea level. Lake Te Roto covers an old volcanic crater which is 80 metres (260 feet) deep.
Tikopia's location is relatively remote. It is sometimes grouped with the Santa Cruz Islands. Administratively, Tikopia belongs to Temotu Province as the southernmost of the Solomon Islands. Some discussions of Tikopian society include its nearest neighbour, the even tinier island of Anuta.
While it is located in Melanesia, the people of Tikopia are culturally Polynesian. Their language, Tikopian, is a member of the Samoic branch of the Polynesian languages. The linguistic analysis indicates that Tikopia was colonized by seafaring Polynesians, mostly from the Ellice Islands (Tuvalu).
The time frame of the migration is not precisely identified but is understood to be some time between the 10th century to the mid-13th century. The arrival of the voyagers in Anuta could have occurred later. The pattern of settlement that is believed to have occurred is that the Polynesians spread out from Tonga and other islands in the central and south eastern Pacific. During pre-European-contact times there was frequent canoe voyaging between the islands as Polynesian navigation skills are recognised to have allowed deliberate journeys on double-hull sailing canoes or outrigger canoes. The voyagers moved into the Tuvaluan atolls as a stepping stone to migration into the Polynesian outlier communities in Melanesia and Micronesia.
