France began to establish colonies in North America, the Caribbean and India in the 17th century but lost most of its possessions following its defeat in the Seven Years' War. The North American possessions were lost to Britain and Spain but the latter returned Louisiana (New France) to France in 1800. The territory was then sold to the United States in 1803. France rebuilt a new empire mostly after 1850, concentrating chiefly in Africa as well as Indochina and the South Pacific. As it developed, the new French empire took on roles of trade with the motherland, supplying raw materials and purchasing manufactured items. Rebuilding an empire rebuilt French prestige, especially regarding international power and spreading the French language and the Catholic religion. It also provided manpower in the World Wars.
