And eventually, we get to 323, 323 BCE, and Alexander is back in Babylon. And it's over there in Babylon that Alexander dies at the ripe old age of 32. It's mind-blowing to think about how much happened in the 12 years that he was emperor of the Macedonians, or even the Shah and Shah of Persia. He was able to defeat an empire over 200 years old. And what's significant about this is that as he conquered, he encouraged his troops to assimilate. In fact, he was criticized for maybe assimilating a little bit too much. But he dies in Babylon, and it's not clear exactly why he dies.
