How did Christopher Columbus differ from earlier voyages to the Americas?

Christopher Columbus differed from earlier voyages to the Americas primarily in his intent and sponsorship. While earlier expeditions were often exploratory or driven by trade, Columbus's 1492 voyage was commissioned by Spain to find a westward route to Asia, aiming for broader economic gain and territorial expansion. His successful return with news of the New World ignited widespread interest and subsequent colonization efforts, marking the beginning of sustained European engagement with the Americas, unlike previous, more isolated visits.
