Christopher Columbus led a voyage from Spain in 1492 in search of a new trade route to Asia. After 36 days at sea, he landed in the Americas, specifically the Bahamas, believing he had reached Asia. His discoveries inspired further European exploration and colonization of the Americas. The Americas refer to the two continents of North and South America. The "New World" described lands in the Americas that were previously unknown to Europeans, while the "Old World" comprised Europe, Asia, and Africa. Other notable explorers who followed in Columbus's footsteps included Amerigo Vespucci and Vasco Nunez de Balboa. Ferdinand Magellan later led the first expedition to circumnavigate the globe between 1519-15
