of Saint Lucia were the Arawaks, though there may have been other native peoples prior to them. The Arawaks are believed to have come from northern South America, sometime around AD 200–400, as there are numerous archaeological sites on the island where specimens of their pottery have been found. The Arawaks called the island Iouanalao, meaning 'Land of the Iguanas', due to the island's high number of iguanas. The Caribs arrived around AD 800, and seized control from the Arawaks by killing their men and assimilating the women into their own society. They called the island Hewanarau, then later Hewanorra, which means "there where iguanas are found". Early European period It is possible that Christopher Columbus may have sighted the island during his fourth voyage in 1502, but he does not mention the island in his log. Juan de la Cosa noted the island on his map of 1500, calling it El Falcon, and another island to the south Las Agujas. A Spanish cédula from 1511 mentions the island within the Spanish domain, and a globe in the Vatican made in 1520, shows the island as Sancta Lucia. In the late 1550s, the French pirate François le Clerc (known as Jambe de Bois, due to his wooden leg) set up a camp on Pigeon Island, from where he attacked passing Spanish ships. In 1605, an English vessel called the Oliphe Blossome was blown off-course on its way to Guyana, and the 67 colonists started a settlement on Saint Lucia, after initially being welcomed by the Carib chief Anthonie. By 26 September 1605, only 19 survived following continued attacks by the Carib chief Augraumart, so the settlers fled the island. The English tried to settle the island again in 1638, but the Caribs continued to be hostile. Eventually, the French successfully claimed the island in 1650 and they signed a treaty with the Caribs in 1660. In 1664, Thomas Warner (son of Sir Thomas Warner, the governor of St Kitts) claimed Saint Lucia for England but the English fled again in 1666, with the French gaining full control of the island after the signing of the Treaty of Breda. Saint Lucia was made an official French crown colony in 1674, as a dependency of Martinique. 18th and 19th centuries After the slave-based sugar industry developed, both the British and the French found the island attractive. During the 18th century, the island
