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. What I have down here is the best information I could find on the lifespans of these people. And when I have these dotted lines at the beginning, that's when it's unclear when these people were born. So there's different accounts that Cyrus the Great might have been born in 575 BCE, he might have been born closer to 600 BCE, and so that's why I have these dotted lines.
