London Company of Barbary Merchants

The London Company of Barbary Merchants is a joint-stock trading company whose armed merchantmen run the Spanish blockade and trade along the Barbary Coast. In John Blackthorne’s history, it is both an employer and a proving ground: ten years of service as its pilot and shipmaster give him experience navigating contested routes, while his record helps make him a prized choice for a later Dutch expedition.

Nature and Operations

The company equips fighting merchantmen for commerce conducted under the pressure of blockade and armed opposition. Its business therefore joins trade to maritime force: its ships must carry goods through waters patrolled by rivals, rather than rely on safe passage. The novel identifies the Barbary Coast as a central destination for this work and describes the Mediterranean as dangerous for English and Dutch shipping, with Spanish and Portuguese enemies present alongside Ottoman slave galleys and warships.

Blackthorne’s routes indicate the breadth of the company’s maritime world. He piloted to West and North Africa, as far south as Lagos, and through the treacherous Straits of Gibraltar, which were patrolled by Spain, as far north and east as Salerno in the Kingdom of Naples. These passages place the company’s commerce within a network of exposed coasts, strategic straits, and competing naval powers.

Blackthorne’s Service

Blackthorne served the company for ten years as both pilot and shipmaster. The distinction matters: he was not only responsible for steering through unfamiliar or hostile waters but also held command of a vessel. His work made him a professional mariner accustomed to judging routes where navigational charts could be too vague to use and longitude could not be fixed by any available method.

The novel gives particular weight to the knowledge needed to navigate such conditions. A pilot’s rutter could record compass courses between ports and headlands, water depth and seabed, winds and currents, likely storms, safe places to take on water, and the location of shoals, reefs, tides, havens, friends, and enemies. Yet such a guide could contain copying errors or deliberate falsehoods; a pilot could not be certain of its accuracy without having sailed the route. Blackthorne’s years at sea thus represent not merely accumulated experience but practical judgment in a world where written directions remained imperfect.

Career and Consequences

The company’s voyages were profitable for Blackthorne. He used his earnings to buy a 150-ton brig and trade on his own account, though that personal venture ended when a Turkish galley captured and destroyed his ship. The episode marks a boundary between his employment and independent enterprise: the text connects his savings to the company’s profitable voyages, but presents the brig as his own ship, not as company property.

Three years before the expedition that brought him to Japan, the newly formed Dutch East India Company recruited Blackthorne to pilot its first expedition to the New World. Its merchants had acquired, at great cost, a contraband Portuguese rutter believed to reveal the secrets of the Strait of Magellan. They would have preferred one of their own Dutch pilots, but none matched Blackthorne’s ability. His training under Trinity House, Dutch ancestry, and fluency in Dutch made him a compelling choice; the valuable route information made the risk of hiring him worthwhile. His earlier service with the London Company of Barbary Merchants is part of the career that established his standing, even though the novel does not describe the two companies as connected.

Significance

The company’s significance lies in the maritime career and wider commercial contest it helps frame. Its armed trading model shows that commerce in these waters depended on ships capable of operating amid blockade and naval danger. Blackthorne’s service gives him experience in precisely that environment, while his later recruitment around a secret Portuguese rutter shows how navigational knowledge could become a strategic asset sought by rival trading powers. The company is not depicted through its internal leadership or a detailed corporate history; its place in the story is defined chiefly by the work it equips and the seafaring expertise Blackthorne acquires in its service.
