In May 1606, the first Europeans arrived at the island, led by the Portuguese explorers Pedro Fernandes de Queirós and Luis Vaz de Torres. In the 19th century when the islands were known as the New Hebrides, the British possessed economic control of the zone, though by the end of 1880, the economic balance began to favour the French; this transition can be seen in its nickel mines of New Caledonia and plantations. French citizen Ferdinand Chevillard began buying and clearing land around Port Vila to be converted into the largest French plantation on the island. Instead, it was converted into the municipality of Franceville, which declared independence on 9 August 1889, though this only lasted until June of the following year.
