What did land did Christopher Columbus conquer?

Christopher Columbus did not conquer land in the traditional sense but is credited with the European discovery of the Americas. His first voyage in 1492 led him to the Bahamas, specifically an island he named San Salvador, and later to parts of Hispaniola (present-day Haiti and the Dominican Republic) and Cuba. Columbus's expeditions opened the door for subsequent European exploration and colonization of the Americas, but he did not establish permanent colonies or control over the lands he encountered.
