The French were the island's first European settlers. They signed a treaty with the native Island Caribs in 1660. England took control of the island from 1663 to 1667. In ensuing years, it was at war with France fourteen times, and the rule of the island changed frequently (it was ruled seven times each by the French and British). In 1814, the British took definitive control of the island. Because it switched so often between British and French control, Saint Lucia was also known as the "Helen of the West Indies" after the Greek mythological character, Helen of Troy.
Thank you, Camille!
