Pirates of the Medieval World explores the turbulent centuries when piracy became one of the defining forces of medieval maritime history. From the fractured seas that followed the fall of Rome to the rise of Byzantine naval defense, Saracen raiders, Viking fleets, Slavic and Baltic pirates, Italian maritime republics, crusader sea warfare, and the late medieval transition toward privateering, this second book reveals how piracy shaped trade, warfare, empire, religion, and coastal life across Europe and the Mediterranean. More than a story of outlaws and plunder, it is a vivid account of how sea raiders, merchants, kingdoms, and republics fought for control of the waters that connected the medieval world.
