12 People Who Accidentally Changed History
History loves to pretend it runs on grand plans, but most turning points begin because someone wasn’t paying attention. A spilled drink, a wrong door, a shrug at the worst possible time. Humanity is powered by the world’s clumsiest form of accident.
Regular people have sparked revolutions by mishearing instructions or pressing buttons they assumed were decorative. Some even reshaped global politics because they tried to do something simple and failed spectacularly. That’s the secret engine behind half our species’ progress.
So this is a tribute to the accidental trailblazers who changed everything while just trying to get through their day.
