The beliefs and practices of the indigenous peoples of the ethnogeographic group of Pacific Islands known as Polynesia (from Greek poly ‘many’ and nēsoi ‘islands’). Polynesia encompasses a huge triangular area of the east-central Pacific Ocean. The triangle has its apex at the Hawaiian Islands in the north and its base angles at New Zealand (Aotearoa) in the west and Easter Island (Rapa Nui) in the east. It also includes (from northwest to southeast) Tuvalu, Tokelau, Wallis and Futuna, Samoa (formerly Western Samoa), American Samoa, Tonga, Niue, theCook Islands, French Polynesia (Tahiti and the other Society Islands, the Marquesas Islands, the Austral Islands, and the Tuamotu Archipelago, including the Gambier Islands [formerly the Mangareva Islands]), and Pitcairn Island. At the turn of the 21st century, about 70 percent of the total population of Polynesia resided in Hawaii.
The physical environment of the Polynesian islands is not as favourable for human habitation as it might at first seem. It certainly presented difficulties when the ancestors of the Polynesians entered the area some 2,000 to 3,000 years ago, first settling on the western islands—Wallis and Futuna, Samoa, and Tonga—which were devoid of much that was needed for human habitation. As a result, early peoples had to take in a wide variety of subsistence items, including most of the useful plants and all of the domestic animals they required. The physical environment has continued to exert a marked influence on Polynesian culture.
Polynesian cultures have been radically altered by Western colonialism. European explorers navigated much of the area in the latter quarter of the 18th century, and the first missionaries arrived in the late 1700s and early 1800s. Britain annexed New Zealand through the Treaty of Waitangi(1840), but interethnic tension arose between the indigenous Maori. Other colonial powers that laid claim to various parts of Polynesia includedFrance, Germany, New
