After the American Revolution, several thousand Tories and their slaves emigrated to New Providence and nearby islands, hoping to re-establish plantation agriculture. The shallow soils and sparse rainfall doomed this activity to failure, and by the early 19th century the Bahamas had become a nearly vacant archipelago. Salt raking continued here and there, wreck gleaning was profitable in Grand Bahama, but New Providence was the only island with any prosperity because of the large British military establishment. The fortresses began to crumble and were abandoned by 1850. New Providence had two periods of high economic success during the American Civil War and during Prohibition, when it was a smuggling center.
Since 1960, New Providence has become an American vacation destination with many tourist facilities, including a deepened harbour for short-visit cruise ship visitors and hotels offering gambling. Two-thirds of the 300,000 Bahamians live on New Providence, although this proportion has fallen somewhat with the development of Freeport on Grand Bahama
