The Anglo-French hostilities were ended in 1763 by the Treaty of Paris, which involved a complex series of land exchanges, the most important being France's cession to Spain of Louisiana, and to Great Britain the rest of New France except for the islands of St. Pierre and Miquelon. Faced with the choice of retrieving either New France or its Caribbean island colonies of Guadeloupe and Martinique, France chose the latter to retain these lucrative sources of sugar, writing off New France as an unproductive, costly territory. France also returned Minorca to the British. Spain lost control of Florida to Great Britain, but it received from the French the Île d'Orléans and all of the former French holdings west of the Mississippi River. The exchanges suited the British as well, as their own Caribbean islands already supplied ample sugar, and, with the acquisition of New France and Florida, they now controlled all of North America east of the Mississippi.
