Upper Egypt is the southern region of ancient Egypt, characterized by its narrower valley along the Nile River and its significant historical and cultural importance. This area stretches from the city of Aswan to the area around Cairo, and it was known for its distinct regional identity, major cities like Thebes, and its key role in ancient Egyptian civilization. The term 'Upper' refers to its location upstream on the Nile River, as the river flows from south to north.
