Resistance by native Caribs prevented colonization on Saint Vincent until 1719. Disputed between France and the UK for most of the 18th century, the island was ceded to the latter in 1783. Between 1960 and 1962, Saint Vincent and the Grenadines was a separate administrative unit of the Federation of the West Indies. Autonomy was granted in 1969 and independence in 1979.
