Wanderlust World Wanderlust World The question "When did Columbus cross the Atlantic?" contains a typo ("dd" for "did") but refers to history's most consequential maritime crossing. Christopher Columbus's first transatlantic voyage launched from Palos de la Frontera, Spain, on August 3, 1492, and reached the Bahamas (Guanahaní, which he named San Salvador) on October 12, 1492—33 days at sea.
Three ships: Santa María (flagship, 100 tons, 40 crew), Pinta (60 tons, 26 crew), Niña (50 tons, 24 crew). Columbus sailed south to Canary Islands (provisioning, repairs), then west on the Northeast Trade Winds—a route chosen deliberately to exploit known wind patterns.
Columbus sought a western route to Asia (Cipangu/Japan, Cathay/China) for spice trade, bypassing Ottoman-controlled land routes. He underestimated Earth's circumference (using Ptolemy/Strabo vs. Eratosthenes) and overestimated Eurasia's width. He didn't know the Americas existed.
Columbus made four transatlantic voyages total:
The 1492 crossing initiated the Columbian Exchange—biological, cultural, and demographic transformation of hemispheres. Indigenous populations collapsed (disease, violence, enslavement). European colonization accelerated. The voyage's anniversary is celebrated (Columbus Day, Día de la Raza) and contested (Indigenous Peoples' Day).
No ship named "dd" exists in historical records. The crossing was made by Christopher Columbus aboard the Santa María, Pinta, and Niña—a 33-day leap into the unknown that connected worlds.
