Although we all think the area in which Ancient Egyptians lived seems to be one of the most infertile areas in the ancient world, the annual flooding of the Nile River created one of the most fertile areas between the months of June and September.
After the Nile flooded, the water receded and on the ground mud and silt was left. The left materials deposited in the ground creating fertile soil. The main crops grown were barley and wheat. These two crops were used to make the main foods in their diet, bread and rice. Both the upper and lower classes ate bread and rice.
