When we think of pirates, we imagine treasure maps, black flags, and the lawless rogues of the Caribbean. But centuries before the age of the Golden Age of Piracy , the seas of Europe and the Mediterranean were already ruled by far more dangerous and far more influential maritime outlaws. In The Forgotten Pirates , the medieval world comes alive as a turbulent arena where raiders, rulers, merchants, and kingdoms collide on the open sea. Far from being mere criminals, pirates were often instruments of power. They toppled rivals, enriched cities, opened new trade routes, and sometimes changed the course of history itself. From the fierce Viking raiders who helped create Normandy , to the powerful pirate emirates of Crete and Dénia , maritime raiding was woven into the political fabric of the Middle Ages. Pirates disrupted kingdoms, strengthened empires, and shaped the conflicts that would define an era, including the long struggle known as the Hundred Years' War . At the center of this hidden history stand unforgettable figures, among them the legendary Jeanne de Clisson , the noblewoman who turned to the sea in a campaign of vengeance that terrified her enemies on both sides of the English Channel. Blending gripping storytelling with groundbreaking historical insight, The Forgotten Pirates reveals a world where piracy was not just an act of rebellion but a powerful force that shaped diplomacy, commerce, and identity across medieval Europe and the Mediterranean. These were not the pirates of myth. They were the pirates who made history.
