The history of Vanuatu begins obscurely. The commonly held theory of Vanuatu’s prehistory from archaeological evidence supports that peoples speaking Austronesian languages first came to the islands some 3,300 years ago. Pottery fragments have been found dating back to 1300 BC. What little is known of the pre-European contact history of Vanuatu has been gleaned from oral histories and legends. One important early king was Roy Mata, who united several tribes, and was buried in a large mound with several retainers.
European contact
The Vanuatu group of islands first had contact with Europeans in 1606, when the Portuguese explorer Pedro Fernandes de Queirós, sailing for the Spanish Crown, arrived on the largest island and called the group of islands La Austrialia del Espiritu Santo or “The Southern Land of the Holy Spirit”, believing he had arrived in Terra Australis or Australia. The Spanish established a short-lived settlement at Big Bay on the north side of the island. The name Espiritu Santo remains to this day.
Europeans did not return until 1768, when Louis Antoine de Bougainville visited the islands, naming them the Great Cyclades. In 1774, Captain Cook named the islands the New Hebrides, a name that lasted until independence.
In 1825, trader Peter Dillon’s discovery of sandalwood on the island of Erromango began a rush that ended in 1830 after a clash between immigrant Polynesian workers and indigenous Melanesians. During the 1860s, planters in Australia, Fiji, New Caledonia, and the Samoan Islands, in need of labourers, orchestrated a long-term indentured labour trade known as “blackbirding”. At the height of the blackbirding, more than one-half the adult male population of several of the islands worked abroad. Fragmentary evidence indicates that the current population of Vanuatu is greatly reduced compared to pre-contact times.
