This is called the Middle Kingdom. The Middle Kingdom around 2080 BCE to about 1640 BCE, for about 500 years they regained control, and they do move on. They build a canal to the Red Sea, which is going to open up new trading routes. They figure out how to drain the swamps of the upper Nile in order to increase their farmland. They begin building dikes to control the water in a more powerful way. They begin new public work projects. So the Middle Kingdom is important, we're just not going to talk about it a lot right now.
