From Palos de la Frontera to the Moluccas' spice ports, Columbus and Magellan's expeditions shattered medieval cartography and ignited imperial rivalry. This book traces their voyages-the Nina, Pinta, and Santa Maria's Atlantic leap, then Magellan's Strait and Pacific ordeal-revealing navigational daring, crew mutinies, and first encounters that redrew world maps. Drawing from logbooks, royal capitulations, and Pacific archaeology, New Worlds: Columbus to Magellan's Voyages examines how astrolabes, carracks, and cross-cultural exchanges launched the Columbian Exchange and colonial foundations. It portrays exploration as both scientific triumph and human tragedy.
