The Portuguese Discoveries refer to the period during the 15th and 16th centuries when Portugal explored and mapped new territories across the globe. This era was marked by significant maritime advancements, allowing explorers like Prince Henry the Navigator to lead expeditions along the West African coast and into the Atlantic Ocean. These explorations resulted in the establishment of sea routes to India, Brazil, and various islands in the Atlantic and Indian Oceans. The discoveries not only expanded Portugal's influence but also contributed to the Age of Exploration, shaping global trade and cultural exchanges.
