The Falkland Islands (Spanish: Islas Malvinas) have a complex history stretching over five hundred years. Active exploration and colonisation began in the 18th century but a self-supporting colony was not established till the latter part of the 19th century. Nonetheless, the islands have been a matter of controversy, as due to their strategic position in the 18th century their sovereignty was claimed by the French, Spaniards, British and Argentines at various points.
