The "trade" and the slave trade intensified in the 17th century. In Senegal, the French and British competed mainly on two issues, the island of Gorée and St. Louis. On 10 February 1763 the Treaty of Paris ended the Seven Years' War and reconciled, after three years of negotiations, France, Great Britain and Spain. Great Britain returned the island of Gorée to France. Britain then acquired from France, among many other territories, "the river of Senegal, with forts & trading posts St. Louis, Podor, and Galam and all rights & dependencies of the said River of Senegal.".
