New France was a colony settled by France in North America. The regions in New France included Quebec, Acadia, and the Louisiana Territory. Quebec City was its capital. The French settled there after finding Quebec and in doing so created New France. The colony was most valuable for its fur trade. France lost the colony during the French and Indian War and it became part of British North America, except the western part of the Louisiana Territory which France had ceded in 1762 to the Spanish Empire. In 1800 Spain returned that territory to Napoleon, who sold it to the United States in 1803.
