Prior to European contact, there were no unified states in New Caledonia, and no single self-appellation used to refer to its inhabitants. Other words have been coined from "Kanak" in the past few generations: "Kanaky" is an ethno-political name for the island or the entire territory. "Kanéka" is a musical genre associated with the Kanak, stylistically a form of reggae with added flutes, percussion and harmonies. "Kaneka" often has political lyrics and is sung in Drehu, Paici or other Melanesian languages, or in French. The word "kanak" is grammatically invariable. The German racial epithet "Kanake" — which is now applied to all non-whites, even Southern Europeans in some cases, and especially to Turkish immigrants — also derives from the same source, and was originally applied to people from German colonial possessions in Oceania. Melanesian settlement on Grande Terre dates back at least as far as the Lapita culture. However, the origin of Kanak people is unclear. Obsidian transported from New Guinea was found with the earliest New Caledonian Lapita pottery. In addition, some researchers have claimed there is evidence of New Caledonian human habitation dating from 3000 BC (predating Lapita culture by 1500 years), while others claim to have found pre-Lapita pottery. At the Fourth Lapita Conference, held in June 2000, in Canberra, Australia, the question was posed: "Is Lapita Kanak, or is Lapita the oldest and first ancestor of a later culture that is labelled Kanak?" Still another problem in determining the origin and early history of Kanak people is that the archaeological interpretation is in conflict with the views of Kanak people which have become politicized subsequent to colonial rule. The earliest history of Europeans arriving on these islands is when Captain Cook of the United Kingdom landed in these islands in 1775 at a time when there were reportedly 70,000 Kanaks living in the archipelago. Cook gave the name "New Caledonia" to these islands, after Caledonia, his Scottish highlands. Fifty years later, the Protestants of London Missionary Society came to New Caledonia, which was followed by entry of the French Catholics to the island, in 1843. This resulted in a conflict between the two religious factions and eventually the French Catholics' control of the islands prevailed. The island nation was thereafter annexed by France, in 1853.
