Now in a previous video, we talk about the Xia Dynasty, which we're not sure whether it exists because we don't have a lot of historical documentation. But based on legend, it apparently emerged around 2100, 2200 BCE, so we're talking about over 4,000 years ago, and lasted until the emergence of the Shang Dynasty in 1600 BCE. Now the Shang Dynasty, you could view as the first real historical dynasty because we have artifacts, we have archeological evidence, we even have writing, the famous oracle bones of the Shang Dynasty that were used to make decisions to prognosticate about the future. And what's interesting about this writing on these oracle bones that are over 3,000 years old is that modern Chinese script has actually evolved from this over 3,000 year old writing. Also in that Shang Dynasty, we see major bronze artifacts. And once again, it's the first real historical evidence we see of a reasonably large geographic area being unified around the Yellow and the Yangtze River. Now in that video on the Shang Dynasty, we talk about how it eventually falls in 1046 BCE, and it falls to the Zhou Dynasty.
