The document summarizes the establishment and development of French colonies in North America, particularly in Canada and along the St. Lawrence River valley. It describes how the French discovered the profitable fur trade which allowed for the establishment of more permanent settlements. The fur trade created mutual dependencies between the French traders and native populations. The French went on to establish other colonies including those in Acadia and Louisiana throughout the 1600s-1700s, largely exploiting the fur trade networks and relationships with indigenous peoples.
