Saint Martin was split between the Netherlands and France in 1648. The Dutch part became a single Dutch colony in 1818 as Sint Eustatius and Dependencies when France returned its possessions after the Napoleonic Wars. This colony was merged with the colonies Curaçao and Dependencies (the ABC islands) and Suriname with a capital in Paramaribo. When this merge was partly reversed in 1845, the Dutch part of the SSS islands became part of Curaçao and Dependencies with Willemstad as capital. This colony became the Netherlands Antilles in 1952. The Dutch part of the SSS islands initially formed the single "island area" (Dutch: eilandgebied, the main administrative division of the Netherlands Antilles, governed by an Island council) the Leeward islands (Dutch: de Bovenwindse eilanden) until 1983.
