The Old Kingdom

The Old Kingdom, spanning the Third to Sixth Dynasties of Egypt (2686-2181 BCE), saw the prolific construction of pyramids, but declined due to civil instability, resource shortages, and a drop in precipitation.

The First Intermediate Period, the Seventh to Eleventh dynasties, spanned approximately one hundred years (2181-2055 BCE), and was characterized by political instability and conflict between the Heracleopolitan and Theban Kings.
