The remote island of St. Helena, a British possession located in the south Atlantic, is perhaps best known as where Napoleon Bonaparte was exiled/imprisoned for the final six years of his life and where he died in 1821. His legacy on the island remains today, despite his body being disinterred and moved back to France in 1840. His home was at Longwood, one area of the island now ceded to the French in respect of its former resident. The island was discovered and named by the Portuguese in 1502. Until the British took over, many other European countries had or wanted possession of the island because of its location along natural trade routes. Jamestown is the island's only port, named after King James. With 4,000 inhabitants, St. Helena is self supporting, growing primarily potatoes and flax. However, its primary economic generator is the sale of the rare St. Helena postage stamp.
