Many times people forget about AE soceity once ther conquest of Alexander the Great wrestles Egypt from the Persians. What people miss out is the history of indigenous Upper Egyptians around the areas of Luxor[Thebes] who fought the Ptolomeys tooth and nail to keep their own independence. Even after many years the southern Upper Egyptian part was hard for the Ptolomeys to govern because of their resistence. During this time Upper Egypt was under independent rule with their own line of pharoahs. People say the last pharoah was dated to the 32 dyansty with Nectanebo II which is not reality. Even prior to his existence and later on there were pharoahs that ruled Upper and Lower Egypt. One during the Persian rule was named Khabbash[sp] that was formely regonized at Men-Nefer[Memphis] and managed to throw off the hgemony of the Persians.

When you study AE history don't just stop at the Ptolomeys or the Late period in Egypt. Study them all the way to the Arab invasion to learn the history of the indigenous Egyptian fellahin. It's truly a history that has been neglected due to great misunderstanding. The historical gap is confined to this area. Personally,I find this time period a hidden jewwel.

Anyway,here are some books I recommend:

Life in Egypt Under Roman Rule: Classics in Papyrology
Naphtali Lewis

Egypt After the Pharaohs: 332 Bc-Ad 642 from Alexander to the Arab Conquest
by Alan K. Bowman

Read the books i presented will tell you all about AE soceity under the hegemony of the Ptolomies.
