Episode Transcript

Two thousand years ago, the world looked very different. Great empires ruled over millions of people. Ancient civilizations were already thousands of years old, and vast regions of the planet remained completely unknown to one another. Some of the world's greatest cities were thriving while others that would eventually dominate history had yet to be founded. Yet almost no one living at that time knew that their era would eventually become a dividing line in history.
