Conquerors: How Portugal Forged the First Global Empire

by Roger Crowley

Unfortunately for the Portuguese, these bold extensions had unforeseen consequences. The Malacca strike had been partially undertaken to snuff out Spanish ambitions in the Far East. Instead it provided the personnel, the information, and the maps to advance them. Among those at Malacca was Fernão de Magalhães (Magellan); he returned to Portugal, wealthy from the booty, with a Sumatran slave, baptized as Henrique. When Magalhães quarreled with King Manuel and defected to Spain, he took Henrique with him, as well as Portuguese maps of the spice islands and detailed letters from a friend who had made the voyage. All these he put to use a few years later in the first circumnavigation of the world, under the flag of Spain, during which Henrique was to prove an invaluable interpreter—knowledge that allowed Portugal’s rival to claim the spice islands of the East Indies as its own.
