1494 How a Family Feud in Medieval Spain Divided the World in Half [Audiobook]

Just as the world's oceans were about to be opened by Columbus's epochal voyage, the treaty sought to limit the seas to these two favored Catholic nations. The edict was to have a profound influence on world history: it propelled Spain and Portugal to superpower status, steered many other European nations on a collision course, and became the central grievance in two centuries of international espionage, piracy, and warfare. The treaty also began the fight for "the freedom of the seas"—the epic struggle to determine whether the world's oceans, and thus global commerce, would be controlled by the decree of an autocrat or be open to the ships of any nation—a distinctly modern notion, championed in the early seventeenth century by the Dutch legal theorist Hugo Grotius, whose arguments became the foundation of international law.
