The document summarizes the early fur trade between French colonists and indigenous peoples in North America, as well as the establishment and growth of New France. Initially, natives traded furs for goods like metal tools and beads. This increased their environmental impact and competition between tribes. The French claimed the St. Lawrence Valley for strategic reasons including its northern location and harbor. Warfare between the Iroquois and other tribes led to cycles of violence and prisoner taking. By 1700, the population of New France grew to 15,000, though it remained much smaller than English colonies.
