History is often told as a straightforward story, with clear beginnings and outcomes that seem inevitable. Yet the past was anything but certain. At countless moments, chance, circumstance, and human decisions determined which path the world would follow.
Small changes could have unraveled empires, delayed discoveries, or shifted cultural revolutions beyond recognition. By exploring the pivotal crossroads of history, we uncover not only how the world we know came to be, but also how easily it might have been different.
These hypothetical scenarios remind us that history is fragile, shaped by fleeting choices and unlikely turns. Asking “what if?” reveals just how the world could have looked utterly unfamiliar.
