Christopher Columbus never set foot on what is now the continental United States, yet his 1492 voyage across the Atlantic, backed by the Spanish crown and aimed at finding a westward route to Asia, is the conventional marker historians use for the start of sustained European contact with the Americas — and the reason he appears at all on a United States history site. Columbus made landfall in the Bahamas and explored parts of the Caribbean, convinced to his death that he had reached the outer edge of Asia rather than an entirely unknown hemisphere.
Columbus made three more voyages across the Atlantic between 1493 and 1504, establishing Spanish settlements on Hispaniola that quickly turned to forced labor, tribute extraction, and brutal punishment of the Taino people who lived there. Spanish colonization under Columbus's governorship brought violence, enslavement, and epidemic disease that killed a large share of the Caribbean's Indigenous population within a generation — consequences that flowed directly from the contact his voyages initiated, even though Columbus himself never explored any part of what became the United States.
Columbus was celebrated in the United States for centuries as a symbol of discovery and national origin, with a federal holiday established in his name in 1937. That reputation has been increasingly contested since the late 20th century, as historians and Indigenous advocates pushed to reframe 1492 around the violence and displacement that followed rather than treat it as an unambiguous triumph; several states and cities now mark the same date as Indigenous Peoples' Day instead.
