Christopher Columbus famously sailed the ocean blue in 1492. His expedition, sponsored by the Spanish monarchy of Ferdinand and Isabella, aimed to find a westward route to Asia but instead led him to the Caribbean islands. Columbus made four voyages in total, which opened up the Americas to exploration and eventual colonization by European powers. His arrival in the New World marked a significant turning point in history, leading to widespread cultural exchanges, the Columbian Exchange, and profound changes for indigenous populations. Columbus's voyages remain a pivotal moment in global history, symbolizing the age of exploration and the ensuing complexities of European colonialism.
