was said to have stopped. A French engraving of about 1797 (pictured) shows it still going on, but this may be an anachronism. In April 1801, Gorée was captured by the British again. In January 1804 a small French squadron from Curaçao captured Gorée, but the British recaptured it in March. In March 1815, during his political comeback known as the Hundred Days, Napoleon definitively abolished the slave trade to build relations with Great Britain. This time, abolition continued. As the trade in slaves declined in the late eighteenth century, Gorée converted to legitimate commerce. The tiny city and port were ill-situated for the shipment of industrial quantities of peanuts, which began arriving in bulk from the mainland. Consequently, its merchants established a presence directly on the mainland, first in (1840) and then in Dakar (1857). Many of the established families started to leave the island. Civic franchise for the citizens of Gorée was institutionalized in 1872, when it became a French with an elected mayor and a municipal council. , the first African deputy elected to the French National Assembly (served 1914 to 1934), was born on Gorée. From a peak of about 4,500 in 1845, the population fell to 1,500 in 1904. In 1940 Gorée was annexed to the municipality of Dakar. From 1913 to 1938, Gorée was home to the , a government teachers' college run by the French Colonial Government. Many of the school's graduates would one day lead the struggle for independence from France. In 1925 African-American historian, sociologist, and Pan-Africanist W. E. B. Du Bois wrote of the school "On the picturesque island of Goree whose ancient ramparts face modern and commercial Dakar I saw two or three hundred fine black boys of high school rank gathered in from all Senegal by competitive tests and taught thoroughly by excellent French teachers in accordance with a curriculum which, as far as it went, was equal to that of any European school," while faulting Colonial France for how limited its public education infrastructure was in the country overall and expressing pessimism about further investment. Gorée is connected to the mainland by regular 30-minute ferry service, for pedestrians only; there are no cars on the island. Senegal's premier tourist site, the island was listed as a UNESCO World Heritage Site in 1978. It now serves mostly as a memorial to the slave trade. Many of the historic
