What was the structure of the Ancient Egyptian state? Who made up the bulk of its population?

At the head of the united Egypt was a ruler who was called Pharaoh. All power in the country and all land in the state belonged to him. The nobles obeyed the Pharaoh. They administered the court, punished the guilty, supervised the construction of roads and canals, and collected taxes for the treasury. The nobles were helped to govern the country by officials, who in Egypt were called scribes. Most of the population was made up of farmers. The lowest level was occupied by slaves.
