New France, though a proprietary colony, was governed by the company, which appointed governors for Canada and Acadia, and a few dependent officers. The kings of France remained interested in the colony, both because of the vast potential wealth of the area and because the crown might have to resume the powers of government given to the Hundred Associates. Government was, in fact, very much what it would have been if the colony had been directly under the rule of the crown. In 1647 a council was established in New France that included the governor, the chief religious authority, the superior of the Jesuits, and the governor of Montreal. During the brief rule of the Community of Habitants, representatives (syndics) of the people of Quebec, Trois Rivières, and Montreal were consulted on local matters. However, this was the nearest approach to anything resembling representative government; by and large, government in New France was authoritarian and highly paternalistic.

The assumption of direct royal control by Louis XIV in 1663 and the colonial ambitions of his great finance minister, Jean-Baptiste Colbert, led to a recasting of French colonial policy and of the government of New France. Colbert entrusted commercial policy to a new Company of the West Indies. Politically, he made New France a royal province, governed much like a province of France itself. New France was to be controlled by three persons: a governor, an intendant, and a bishop. The governor was the largely titular head of this triumvirate, although he was responsible for matters of defense and relations with the First Nations. He was aided in his decision making by the Superior Council (at first called the Sovereign Council), which was to advise him during the long periods when he had no communication with France. The intendant was responsible for internal matters, and the bishop administered mission work and the church. Both the intendant and the bishop were members of the council. Bitter rivalries were not unknown among these officials, particularly as the governor was an aristocrat and the intendant from the bourgeoisie.

Colbert’s reorganization generally gave New France firm and rational government, which was strongly centralized and efficient for the times. Acadia was an exception; torn by feuds among French rivals, claimed by England, and occupied by New Englanders eager to exploit its fishery, Acadia did not again become an effective part of New France until 1667–70. The strength of the royal government was in inverse proportion to the weakness of a small and scattered population. Great efforts made by the first intendant, Jean Talon, resulted in the influx of thousands of settlers (including hundreds of women) to New France in the 1660s and early ’70s. In 1666 the population reached 3,215, and a decade later it was about 8,500; thereafter, however, the population grew largely by natural increase, though at a prodigious rate. Most of the population lived in the three towns (Montreal, Quebec, and Trois Rivières) and in seigneuries along the banks of the St. Lawrence between Quebec and Montreal. However, scores of the men went inland with trading canoes, and some of these voyageurs remained inland permanently, marrying First Nations women and fathering the Métis, people of mixed French and First Nations ancestry.

The frontier of New France was not a broad front of advance but rather a penetration of the wilderness via the rivers in search of furs and strategic position. It was necessary to continue alliances with First Nations, and those alliances were constantly challenged by the Iroquois, who controlled the region south of Lakes Ontario and Erie in the 1650s. War with the Iroquois continued, as did the push into the interior, and in 1673 the explorers Louis Jolliet and Jacques Marquette, a Jesuit priest, traveled down the Mississippi River as far as its confluence with the Arkansas River.
