The St. Lawrence River provided a direct route to the heart of the North American continent, allowing the French to explore and claim vast territories.
The region was rich in fur-bearing animals (beaver, otter, mink). The lucrative fur trade motivated French control of this valuable resource.
Religious zeal drove efforts to convert indigenous peoples to Catholicism.
Settlements exploited natural resources including timber, fish, and minerals.
Competition with England for control of North America made the St. Lawrence a strategic advantage.
