The narrative traces early voyages of Arctic and North Atlantic explorers, recounting attempts to find passages and the exploits of figures such as Henry Hudson and Radisson, then follows the creation and evolution of a chartered fur‑trading corporation. It describes company governance, secret oaths, trading practices, clashes with French rivals and raiders, inland expeditions that pushed posts up river systems toward the interior and the Pacific, southern trade brigades reaching California and Hawaii, and episodic drama around forts, rescues, and corporate politics, all assembled from extensive archival journals and minute books.
