Ancient Egypt, or the Egyptian Empire, was a society that began about 3150 BC, and lasted until 20 BC when it was invaded by the Roman Empire.
It grew along the River Nile and was at its most powerful in the second millennium BC. Its land went from the Nile delta to Nubia, a kingdom which today is mostly in the Sudan.
For most of its history, Egypt was prosperous, since the water from the Nile made sure that the Egyptians would have good crops. Crops were grown after the Nile flood water went down.
The Egyptians created a way of writing using hieroglyphs, built huge temples and tombs, traded with other areas, and had a powerful army. Their religion had many gods, and its priests were powerful and rich. Their rulers, called Pharaohs, were thought to be close to the gods.
