Answer by ibn Masud
Islam bring back the people of Egypt to the path of the Islamic aqidah (believe). This is the most significant impact. Prior to Islam many of them are pagans (who dwell with all kind of devil worshipping, or associate Allah with something else) or being led astray from the true religion as brought to them by earlier Messenger of Allah.

Expel the Romans from Egypt ..
spread of Islam in southern and northern Egypt..
(Al-Hakim bi-Amr Allah) in 1000 A.D prevent the use of the ancient Egyptian language .. And requested the use of Arabic only .. And threatened to cut off the tongue of any person who speaks the language Egyptian Coptic.
Now the Egyptians speak the language of Egyptian-Arab mixed in both Arabic and Coptic .. and use Arabic characters.
