There are 7 social classes in Egypt. First was the kings who had their own palace and was treated like gods. The second is the priest, they were the only people that could talk to the gods and told the people what they need to sacrifice. The third one is the nobles (land owners). They were the middle class and had restrictions but had a very easy life. The fourth is the military leaders, they led armies. The fifth is the merchants, artisans, and scribes. They are low on the social class but lived in town. The sixth is farmer, herders, and fishermen. They usually live outside of town in mud houses and usually trade with neighbors. The seventh one is slaves, they were treated with little respect and usually owned by kings, priest, or nobles.
