We see a miniature model of a granary dating back to the 12th Dynasty of the Middle Kingdom around 2000 BC. We note in the methods of storing grain in ancient Egypt that there is always a writer who writes everything in records more than four thousand years ago, the model is in the Metropolitan Museum.
The Pharaonic era in the history of Egypt extends to about three thousand from 3200 BC until Alexander the Great entered Egypt in 323 BC.
During the Pharaonic era, Egypt witnessed many stages of renaissance and progress that left a huge legacy of the manifestations and effects of civilization, construction, science and arts.
Historians divide the pharaonic era in the history of Egypt into three successive sections: the old state, the middle state, and the modern state.
Historians also divide this era into thirty ruling dynasties divided into these three phases of Egypt’s history, the Archaic period (dynasties 1 - 2), the Old Kingdom (dynasties 3 to 6), the first middle age (dynasties 7 to 10) and the Middle Kingdom ( Dynasties 11, 12), the second middle age (dynasties 13 to 17), the modern state (dynasties 18 to 20), the late era (dynasties 21 to 30).
