Christopher Columbus was the famous explorer known for his voyages to the New World in the late 15th century. Sponsored by Spain, he embarked on his first journey in 1492, aiming to find a westward route to Asia. Instead, Columbus landed in the Bahamas, paving the way for European exploration and colonization of the Americas. His expeditions, although controversial for their impacts on indigenous populations, are credited with connecting the Old World and the New World, leading to extensive cultural exchanges and significant historical ramifications, including the Columbian Exchange and the eventual establishment of European colonies.
