He ends up dying in 522, but before he dies in 522, he is able to conquer Egypt in 525 BCE, so right around there. And you can imagine that while he's conquering Egypt, and let me keep drawing this family tree, so now we have Cambyses, Cambyses, Cambyses II, he goes off, makes his real goal to conquer Egypt, and that's a big deal. Remember, this is ending thousands of years of the rule by the native pharaohs. They start, these now foreign rulers start calling themselves the pharaohs of Egypt as well, but they get put in to, Egypt becomes part of the Persian Empire because of Cambyses. But you can imagine with the Shah and Shah, with the king of kings often doing conquest in Egypt, it leaves a little power vacuum back in the center of the empire. And this is when things get a little bit sketchy. So Cyrus does have another son.
