The Middle Kingdom
For over four centuries Egypt had enjoyed peace and prosperity. In 2200 B.C., this was all about to change. The peace gave way to a series of civil wars that would last for the next 150 years.
Local leaders rose in rebellion against the powerful king, and eventually crumbled the empire. For the next 150 years Egypt would be ruled by a number of local leaders.
Then, around 2050 B.C., a new king united Egypt once again. This leader moved the capital from Memphis to Thebes where he and his descendents would rule Egypt for the next 1,800 years.
