pre-Columbian era; however, they also do not fit into a cultural subregion of Oceania and the Pacific, as is the case with Easter Island, which historically was Polynesian. Europe and North America : As a constituent part of the Danish Realm, Greenland is a non-sovereign country within the Kingdom of Denmark. Fully located on the North American tectonic plate, and close to the mainland, Greenland is considered to be geographically a part of North America, with the United Nations categorizing them as such. Although it is politically associated with Europe and internationally represented by a European state (including in the Council of Europe), it is autonomous. Historically and ethnically, its native population is of North American tradition, although it also shares cultural links with other native peoples bordering the Arctic Sea in Northern Europe and Asia (today in Norway, Sweden, Finland and Russia), as well as in North America (Alaska in the U.S., Northwest Territories, Nunavut and northern parts of Quebec and Labrador in Canada). Greenland was part of Danish territory and within the territory of the European Union, but voted for more autonomy and is now excluded from the EU. Europe, North America, and South America : Though most of the Kingdom of the Netherlands' landmass is in Europe, it also includes six island territories in the Lesser Antilles archipelago of the Caribbean Sea: the Dutch Caribbean. Within the Lesser Antilles archipelago, three territories are in the Leeward Islands group (considered part of the continent of North America) and three in the Leeward Antilles group (on the South American continental shelf). Since the dissolution of the Dutch Antilles in 2010, the sovereign Kingdom of the Netherlands has been administratively divided into four non-sovereign constituent "countries": Aruba, Curaçao, Sint Maarten and the Netherlands — the last of which includes the islands of Bonaire, Saint Eustatius and Saba (collectively known as the BES islands or the Caribbean Netherlands) as "special municipalities", making it a non-sovereign transcontinental constituent country within the Kingdom. Europe, North America, South America, Oceania, Africa, and Antarctica : Metropolitan France is located in Europe, while the five overseas departments and regions, five overseas collectivities, and one Sui generis collectivity are located in other continental regions. Guadeloupe, Martinique, Saint Barthélemy, Saint Martin, and Saint Pierre and Miquelon are located in North America, French Guiana is located in South America, Mayotte and Réunion are located in Africa, and French Polynesia,
