Answer: A famine
Explanation:
The Middle Kingdom of ancient Egypt was a period between 2030 to 1650 B.C when Egypt regained stability after the chaos of the First Intermediate period. It saw great pharaohs such as Senusret III and Amenemhat III.
Towards the end of the reign of Pharaoh Amenemhat III, the river Nile saw its flood levels drop which the Egyptians were very reliant on. This created a famine where crop yields were dangerously low leading to the decline of the Middle Kingdom.
