◊ Soon after the Sumerian civilization began, the Nile valley of Lower and Upper Egypt was unified under the Pharaohs approximately around 3150 BC. Since then, Ancient Egypt experienced 3 high points of civilization, the so-called “Kingdom” periods:
The Old Kingdom (2686–2181),
The Middle Kingdom (2055–1650) and, most notably,
The New Kingdom (1550–1069).
The history of Ancient Egypt is concluded by the Late Period (664–332 BC), immediately followed by the history of Egypt in Classical Antiquity, beginning with Ptolemaic Egypt.
