French settlement dates from 1604. In the Dutch wars of Louis XIV, Cayenne was captured (1676) by the Dutch but was later retaken. The Portuguese and British occupied it during the Napoleonic Wars, but the Congress of Vienna (1815) restored French authority. French Guiana was used as a penal colony and place of exile during the French Revolution, and under Napoleon III permanent penal camps were established. Devils Island, one of the les du Salut, off the coast, became notorious. The penal colonies were evacuated after World War II
