The beginning of the Early Dynastic Period is marked by the unification of Lower and Upper Egypt around 3100 B.C., lasting until about 2686 B.C. The era included the 1st and 2nd Dynasties. It was during this time that many Egyptian mythology, art, and architecture took shape.

3000 BC	Egyptians start to keep track of time based on three natural cycles: the solar year, the lunar month and the solar day
3000 BC	The Egyptians worship the sun. Early solar deities were mostly goddesses: Hathor, Sekhmet, Wadjet, Menhit, Nut, Bat, and Bast. Hathor, then Isis, each gave birth to Horus and Ra
2920 BC	The 1st Dynasty starts with Narmer (Pharaoh Menes). He wins many battles in the north and unites most of Egypt. He centers the capital at Hiku-Ptah (Memphis), where the Ptah cult was located.

2890 BC	The 2nd Dynasty begins with Hotepsekhemwy, the king’s Horus name. “Hotep” means “to be pleased” or “peaceful”, though it can also mean “conciliation,” which might refer to the reconciliation of Upper and Lower Egypt during his time.
