Portuguese Explorers' Search for New Trade Routes
Portuguese explorers led the way in early exploration, seeking new trade routes to China, India, and West Africa. Through expeditions, such as Vasco da Gama's journey to India, they expanded trade networks and discovered new lands, like the Cape of Good Hope. The exploration efforts also led to unintended consequences such as the buying of slaves in West Africa. Queen Isabella of Spain sponsored Christopher Columbus's voyages, where he thought he had reached Asia but actually landed in the Americas, marking a significant moment in history.
