And the empire, as we'll see, which lasts thousands of years, every one of these spaces is 100 years, so we're gonna go over a huge time span. But the ancient Egyptian civilization is roughly divided into three kingdoms. You have the Old Kingdom, which went from about 20, right from about the 27th century BCE up to about the 17th century BCE. You have the Middle Kingdom, and you have the New Kingdom. And once again, this is spanning right over here over 1,000 years of history. And in between those, you have these intermediate periods where the kingdom or the empire was a little bit more fragmented. You have, in some of these intermediate periods, you have some foreign rule.
