Ancient Egypt was centered around the Nile River, which provided fertile land for agriculture. The civilization was divided into Upper and Lower Egypt, which were united under King Menes around 3100 BC. Egyptian society was highly stratified, with powerful pharaohs at the top who were considered divine rulers. Specialized workers such as scribes, artisans, and builders supported the pharaohs and helped construct grand monuments and cities. Religion also played a central role, with polytheistic beliefs influencing how pharaohs governed and the afterlife being an important concept.
