The English and French held St. Kitts jointly from 1628 to1713. During the 17th century, intermittent warfare between French and English settlers ravaged the island's economy. Meanwhile Nevis, settled by English settlers in 1628, grew prosperous under English rule. St. Kitts was ceded to Great Britain by the Treaty of Utrecht in 1713. The French seized both St. Kitts and Nevis in 1782.
The Treaty of Paris in 1783 definitively awarded both islands to Britain. They were part of the colony of the Leeward Islands from 1871-1956, and of the West Indies Federation from 1958-62. In 1967, together with Anguilla, they became a self-governing state in association with Great Britain; Anguilla seceded late that year and remains a British dependency. The Federation of St. Kitts and Nevis attained full independence on September 19, 1983.
Background: First settled by the English in 1623, the islands along with Anguilla, became an associated state with full internal autonomy in 1967. Anguilla rebelled and was allowed to secede in 1971. St. Kitts and Nevis achieved independence in 1983. In August 1998, a vote in Nevis on a referendum to separate from St. Kitts fell short of the two-thirds majority needed. In late September 1998, Hurricane Georges caused approximately $445 million in damages and limited GDP growth for the year.
