Columbus Reaches the Americas
A navigational error triggers the Columbian Exchange — the most consequential ecological and demographic event since the Agricultural Revolution.
Columbus's voyages initiated permanent contact between the Eastern and Western hemispheres. The resulting exchange of plants, animals, diseases, and people transformed every continent.
Perspective
This isn't a "discovery" — it's a collision. The indigenous populations of the Americas lost 90% of their people, primarily to European diseases. The Columbian Exchange was a biological apocalypse for one hemisphere and an economic windfall for the other. We should never romanticize it.
