Ancient Egyptian civilization developed in northeastern Africa along the Nile River. The river provided water, fertile agricultural land and a natural transportation route through an otherwise arid landscape.
Around 3100 BCE, Upper and Lower Egypt were unified into a single political kingdom. This event is traditionally associated with the ruler known as Menes, often identified with Narmer.
The unification created the foundation for a centralized state ruled by kings who later became known as pharaohs. From this foundation emerged one of the most enduring political and cultural traditions of the ancient world.
