Samuel de Champlain reclaims his role as commander of New France on behalf of Cardinal Richelieu.

New France (French: Nouvelle-France) was the area colonized by France in North America, beginning with the exploration of the Gulf of Saint Lawrence by Jacques Cartier in 1534 and ending with the cession of New France to Great Britain and Spain in 1763 under the Treaty of Paris.

The vast territory of New France consisted of five colonies at its peak in 1712, each with its own administration: Canada, the most developed colony, was divided into the districts of Qubec, Trois-Rivires, and Montral; Hudson Bay; Acadie in the northeast; Plaisance on the island of Newfoundland; and Louisiane. It extended from Newfoundland to the Canadian Prairies and from Hudson Bay to the Gulf of Mexico, including all the Great Lakes of North America.

In the 16th century, the lands were used primarily to draw from the wealth of natural resources such as furs through trade with the various indigenous peoples. In the seventeenth century, successful settlements began in Acadia and in Quebec. In the 1713 Treaty of Utrecht, France ceded to Great Britain its claims over mainland Acadia, Hudson Bay, and Newfoundland. France established the colony of le Royale on Cape Breton Island, where they built the Fortress of Louisbourg.The population rose slowly but steadily. In 1754, New France's population consisted of 10,000 Acadians, 55,000 Canadiens, and about 4,000 settlers in upper and lower Louisiana; 69,000 in total.The British expelled the Acadians in the Great Upheaval from 1755 to 1764, which has been remembered on July 28 each year since 2003. Their descendants are dispersed in the Maritime provinces of Canada and in Maine and Louisiana, with small populations in Chticamp, Nova Scotia and the Magdalen Islands. Some also went to France.

After the Seven Years' War (which included the French and Indian War in America), France ceded the rest of New France to Great Britain and Spain in the Treaty of Paris (1763) (except the islands of Saint Pierre and Miquelon). Britain acquired Canada, Acadia, and French Louisiana east of the Mississippi River, except for the le d'Orlans, which was granted to Spain with the territory to the west. In 1800, Spain returned its portion of Louisiana to France under the secret Treaty of San Ildefonso, and Napoleon Bonaparte sold it to the United States in the Louisiana Purchase of 1803, permanently ending French colonial efforts on the American mainland.

New France eventually became absorbed within the United States and Canada, with the only vestige of French rule being the tiny islands of Saint Pierre and Miquelon. In the United States, the legacy of New France includes numerous place names as well as small pockets of French-speaking communities.

Samuel de Champlain (French: [samɥɛl də ʃɑ̃plɛ̃]; c. 13 August 1567 – 25 December 1635) was a French colonist, navigator, cartographer, draftsman, soldier, explorer, geographer, ethnologist, diplomat, and chronicler. He made between 21 and 29 trips across the Atlantic Ocean, and founded Quebec, and New France, on 3 July 1608. An important figure in Canadian history, Champlain created the first accurate coastal map during his explorations, and founded various colonial settlements.

Born into a family of sailors, Champlain began exploring North America in 1603, under the guidance of his uncle, François Gravé Du Pont. After 1603, Champlain's life and career consolidated into the path he would follow for the rest of his life.From 1604 to 1607, he participated in the exploration and creation of the first permanent European settlement north of Florida, Port Royal, Acadia (1605).

In 1608, he established the French settlement that is now Quebec City.Champlain was the first European to describe the Great Lakes, and published maps of his journeys and accounts of what he learned from the natives and the French living among the Natives.

He formed long time relationships with local Montagnais and Innu, and, later, with others farther west—tribes of the Ottawa River, Lake Nipissing, and Georgian Bay, and with Algonquin and Wendat; he also agreed to provide assistance in the Beaver Wars against the Iroquois.

Late in the year of 1615, Champlain returned to the Wendat and stayed with them over the winter, which permitted him to make the first ethnographic observations of this important nation, the events of which form the bulk of his book Voyages et Decouvertes faites en la Nouvelle France, depuis l’année 1615 published in 1619.In 1620, Louis XIII of France ordered Champlain to cease exploration, return to Quebec, and devote himself to the administration of the country.In every way but formal title, Samuel de Champlain served as Governor of New France, a title that may have been formally unavailable to him owing to his non-noble status.Champlain established trading companies that sent goods, primarily fur, to France, and oversaw the growth of New France in the St. Lawrence River valley until his death, in 1635.

Champlain is memorialized as the "Father of New France", "Father of Acadia", or in French "Père de la Nouvelle-France" with many places, streets, and structures in northeastern North America bearing his name, most notably Lake Champlain.
