So Cyrus was able to conquer a lot of what you see here in green, but not all of it. And especially, he was not able to get to Egypt. That would be left to his son Cambyses. So in 530, Cyrus dies and Cambyses takes over. And just so you read how I made this timeline, and I made this timeline really to help myself understand the various Shah and Shahs, or king of kings of Iran. So Cyrus the Great was the Shah and Shah, king of kings, and then Cambyses II was the next one, is that this timeline up here, this shows who is in charge. So you see from 550, 549, all the way to 530, I have it yellow and that's because Cyrus the Great was in charge of what is called the Achaemenid Empire, or I guess you could say this first great Persian Empire.
